XmText(3X) XmText(3X) NAME XmText - The Text widget class SYNOPSIS #include <Xm/Text.h> DESCRIPTION Text provides a single-line and multiline text editor for customizing both user and programmatic interfaces. It can be used for single-line string entry, forms entry with verification procedures, and full-window editing. It provides an application with a consistent editing system for textual data. The screen's textual data adjusts to the application writer's needs. Text provides separate callback lists to verify movement of the insert cursor, modification of the text, and changes in input focus. Each of these callbacks provides the verification function with the widget in- stance, the event that caused the callback, and a data structure spe- cific to the verification type. From this information the function can verify if the application considers this to be a legitimate state change and can signal the widget whether to continue with the action. The user interface tailors a new set of translations. The default translations provide key bindings for insert cursor movement, deletion, insertion, and selection of text. Text allows the user to select regions of text. Selection is based on the model specified in the Inter-Client Communication Conventions Man- ual (ICCCM). Text supports primary and secondary selection. Mouse Selection The Text widget allows text to be edited, inserted, and selected. The user can cut, copy, and paste text using the clipboard, primary trans- fer, or secondary transfer. Text also provides a Drag and Drop facility that enables the user to copy or move data within Text or to a differ- ent widget. When keyboard focus policy is set to EXPLICIT, the widget that receives focus is the destination widget. In POINTER mode, any keyboard or mouse operation (except secondary selection) in an editable widget establishes that widget as the destination. If a destination widget becomes insensitive or uneditable, it forfeits its destination status. In EXPLICIT mode, when a widget becomes insen- sitive, the focus moves to another widget. If that widget is editable, it becomes the destination widget; otherwise, there is no destination widget. The text of any insensitive Text widget is stippled, indicat- ing its state to the user. The insertion cursor, displayed as an I-beam, shows where input is in- serted. Input is inserted just before the insertion cursor. Classes Text inherits behavior and resources from Core and Primitive classes. The class pointer is xmTextWidgetClass. The class name is XmText. New Resources The following table defines a set of widget resources used by the pro- grammer to specify data. The programmer can also set the resource val- ues for the inherited classes to set attributes for this widget. To reference a resource by name or by class in a .Xdefaults file, remove the XmN or XmC prefix and use the remaining letters. To specify one of the defined values for a resource in a .Xdefaults file, remove the Xm prefix and use the remaining letters (in either lowercase or uppercase, but include any underscores between words). The codes in the access column indicate if the given resource can be set at creation time (C), set by using XtSetValues (S), retrieved by using XtGetValues (G), or is not applicable (N/A).

Specifies the list of callbacks that is called when the user invokes an event that calls the Activate() function. The type of the structure whose address is passed to this callback is XmAnyCallbackStruct. The reason sent by the callback is XmCR_ACTIVATE. Ensures that the visible text contains the insert cursor when set to True. If the insert cursor changes, the contents of Text may scroll in order to bring the inser- tion point into the window. Indicates the position in the text where the current insert cursor is to be located. Position is determined by the number of characters from the beginning of the text. The first character position is 0. Indicates that the user can edit the text string when set to True. Prohibits the user from editing the text when set to False. Specifies the set of keyboard bindings used in Text. The default keyboard bindings (XmSINGLE_LINE_EDIT) provides the set of key bindings to be used in editing single-line text. The multiline bind- ings (XmMULTI_LINE_EDIT) provides the set of key bindings to be used in editing multiline text. The results of placing a Text widget inside a ScrolledWindow when the Text's XmNeditMode is XmSINGLE_LINE_EDIT are undefined. Specifies the list of callbacks called when Text accepts input focus. The type of the structure whose address is passed to this callback is XmAnyCallbackStruct. The reason sent by the callback is XmCR_FOCUS. Specifies the list of callbacks called when an event causes the Text widget to gain ownership of the primary selection. The reason sent by the callback is XmCR_GAIN_PRIMARY. Specifies the list of callbacks called when an event causes the Text widget to lose ownership of the primary selection. The reason sent by the callback is XmCR_LOSE_PRIMARY. Specifies the list of callbacks called before Text loses input focus. The type of the structure whose address is passed to this callback is XmTextVerifyCallbackStruct. The reason sent by the callback is XmCR_LOSING_FOCUS. Specifies the distance between the top edge of the widget window and the text, and between the bottom edge of the widget window and the text. Specifies the distance between the left edge of the widget window and the text, and between the right edge of the widget window and the text. Specifies the maximum length of the text string that can be entered into text from the keyboard. This value must be non- negative. Strings that are entered using the XmNvalue resource or the XmTextSetString function ignore this resource. Specifies the list of callbacks called before text is deleted from or in- serted into Text. The type of the structure whose address is passed to this callback is XmTextVerifyCallbackStruct. The rea- son sent by the callback is XmCR_MODIFYING_TEXT_VALUE. When mul- tiple Text widgets share the same source, only the widget that initiates the source change will generate the XmNmodifyVerify- Callback. If both XmNmodifyVerifyCallback and XmNmodifyVerifyCallbackWcs are registered callback lists, the procedure(s) in the XmNmodi- fyVerifyCallback list are always executed first; and the result- ing data, which may have been modified, is passed to the XmNmod- ifyVerifyCallbackWcs callback routines. Specifies the list of callbacks called before text is deleted from or inserted into Text. The type of the structure whose address is passed to this callback is XmTextVerifyCallbackStructWcs. The reason sent by the callback is XmCR_MODIFYING_TEXT_VALUE. When multiple Text widgets share the same source, only the widget that initiates the source change will generate the XmNmodifyVerifyCallbackWcs. If both XmNmodifyVerifyCallback and XmNmodifyVerifyCallbackWcs are registered callback lists, the procedure(s) in the XmNmodi- fyVerifyCallback list are always executed first; and the result- ing data, which may have been modified, is passed to the XmNmod- ifyVerifyCallbackWcs callback routines. Specifies the list of callbacks called before the insert cursor is moved to a new po- sition. The type of the structure whose address is passed to this callback is XmTextVerifyCallbackStruct. The reason sent by the callback is XmCR_MOVING_INSERT_CURSOR. It is possible for more than one XmNmotionVerifyCallbacks to be generated from a single action. Specifies the source with which the widget dis- plays text. If no source is specified, the widget creates a de- fault string source. This resource can be used to share text sources between Text widgets. Displays the position of text at the top of the window. Position is determined by the number of characters from the beginning of the text. The first character position is 0. If the XmNeditMode is XmMULTI_LINE_EDIT, the line of text that contains the top character is displayed at the top of the widget without shifting the text left or right. XtGetValues for XmN- topCharacter returns the position of the first character in the line that is displayed at the top of the widget. Specifies the string value of the Text widget as a char* data value. XmNvalue and XmNvalueWcs are both defined, the value of XmNvalueWcs su- persedes that of XmNvalue. XtGetValues returns a copy of the value of the internal buffer and XtSetValues copies the string values into the internal buffer. Specifies the list of call- backs called after text is deleted from or inserted into Text. The type of the structure whose address is passed to this call- back is XmAnyCallbackStruct. The reason sent by the callback is XmCR_VALUE_CHANGED. When multiple Text widgets share the same source, only the widget that initiates the source change will generate the XmNvalueChangedCallback. This callback represents a change in the source in the Text, not in the Text widget. The XmNvalueChangedCallback should occur only in pairs with a XmN- modifyVerifyCallback, assuming that the doit flag in the call- back structure of the XmNmodifyVerifyCallback is not set to False. Specifies the string value of the Text widget as a wchar_t* data value. This resource cannot be specified in a re- source file. If XmNvalue and XmNvalueWcs are both defined, the value of XmN- valueWcs supersedes that of XmNvalue. XtGetValues returns a copy of the value of the internal buffer encoded as a wide character string. XtSetValues copies the value of the wide character string into the internal buffer. Specifies whether the bell should sound when the verification returns without continuing the action. The default depends on the value of the ancestor VendorShell's XmNaudibleWarning resource. XmText Input Resource Set Class: XmCPendingDelete Default: True Type: Boolean Access: CSG Class: XmCSelectionArray Default: default array Type: XtPointer Access: CSG Class: XmCSelectionArrayCount Default: 4 Type: int Access: CSG Class: XmCSelectThreshold Default: 5 Type: int Access: CSG Indicates that pending delete mode is on when the Boolean value is True. Pending deletion is defined as deletion of the selected text when an insertion is made. Defines the actions for multi- ple mouse clicks. The value of the resource is an array of Xm- TextScanType elements. XmTextScanType is an enumeration indicat- ing possible actions. Each mouse click performed within half a second of the previous mouse click increments the index into this array and performs the defined action for that index. The possible actions in the order they occur in the default array are: XmSELECT_POSITION--resets the insert cursor position XmSE- LECT_WORD--selects a word XmSELECT_LINE--selects a line of text XmSELECT_ALL--selects all of the text Indicates the number of elements in the XmNselectionArray resource. The value must not be negative. Specifies the number of pixels of motion that is required to select the next character when selection is per- formed using the click-drag mode of selection. The value must not be negative. XmText Output Resource Set Class: XmCBlinkRate Default: 500 Type: int Access: CSG Class: XmC- Columns Default: dynamic Type: short Access: CSG Class: XmCCursorPosi- tionVisible Default: True Type: Boolean Access: CSG Class: XmCFontList Default: dynamic Type: XmFontList Access: CSG Class: XmCResizeHeight Default: False Type: Boolean Access: CSG Class: XmCResizeWidth De- fault: False Type: Boolean Access: CSG Class: XmCRows Default: dynamic Type: short Access: CSG Class: XmCWordWrap Default: False Type: Boolean Access: CSG Specifies the blink rate of the text cursor in milliseconds. The time indicated in the blink rate relates to the time the cursor is visible and the time the cursor is invisible (that is, the time it takes to blink the insertion cursor on and off is twice the blink rate). The cursor does not blink when the blink rate is set to zero. The value must not be negative. Specifies the initial width of the text window as an integer number of characters. The width equals the number of characters specified by this resource multiplied by the maximum character width of the associated font. For proportionate fonts, the actual number of characters that fit on a given line may be greater than the value specified. The value must be greater than 0. The default value depends on the value of the XmNwidth resource. If no width is specified the default is 20. Indicates that the insert cur- sor position is marked by a blinking text cursor when the Boolean value is True. Specifies the font list to be used for Text. If this value is NULL at initialization, the font list is initialized by looking up the parent hierarchy of the widget for an ancestor that is a subclass of the XmBulletinBoard or Vendor- Shell widget class. If such an ancestor is found, the font list is initialized to the XmNtextFontList of the ancestor widget. If no such ancestor is found, the default is implementation depen- dent. Text searches the font list for the first occurrence of a font set that has a XmFONTLIST_DEFAULT_TAG. If a default element is not found, the first font set in the font list is used. If the list contains no font sets, the first font in the font list will be used. Refer to XmFontList(3X) for more information on a font list structure. Indicates that Text attempts to resize its height to accommodate all the text contained in the widget when the Boolean value is True. If the Boolean value is set to True, the text is always displayed starting from the first position in the source, even if instructed otherwise. This attribute is ig- nored when the application uses a ScrolledText widget and when XmNscrollVertical is True. Indicates that Text attempts to re- size its width to accommodate all the text contained in the wid- get when the Boolean value is True. This attribute is ignored if XmNwordWrap is True. Specifies the initial height of the text window measured in character heights. This attribute is ignored if the text widget resource XmNeditMode is XmSINGLE_LINE_EDIT. The value must be greater than 0. The default value depends on the value of the XmNheight resource. If no height is specified the default is 1. Indicates that lines are to be broken at word breaks (that is, the text does not go off the right edge of the window) when the Boolean value is True. Words are defined as a sequence of characters separated by white space. White space is defined as a space, tab, or newline. This attribute is ignored if the text widget resource XmNeditMode is XmSINGLE_LINE_EDIT. The following resources are used only when text is created in a ScrolledWindow. See the man page for XmCreateScrolledText. XmText ScrolledText Resource Set Class: XmCScroll Default: True Type: Boolean Access: CG Class: XmC- ScrollSide Default: dynamic Type: Boolean Access: CG Class: XmCScroll- Side Default: False Type: Boolean Access: CG Class: XmCScroll Default: True Type: Boolean Access: CG Adds a ScrollBar that allows the user to scroll horizontally through text when the Boolean value is True. This resource is forced to False when the Text widget is placed in a ScrolledWin- dow with XmNscrollingPolicy set to XmAUTOMATIC. Indicates that the vertical ScrollBar should be placed on the left side of the scrolled text window when the Boolean value is True. This at- tribute is ignored if XmNscrollVertical is False or the Text re- source XmNeditMode is XmSINGLE_LINE_EDIT. The default value may depend on the value of the XmNstringDirection resource. Indi- cates that the horizontal ScrollBar should be placed on the top side of the scrolled text window when the Boolean value is True. Adds a ScrollBar that allows the user to scroll vertically through text when the Boolean value is True. This attribute is ignored if the Text resource XmNeditMode is XmSINGLE_LINE_EDIT. This resource is forced to False when the Text widget is placed in a ScrolledWindow with XmNscrollingPolicy set to XmAUTOMATIC. Inherited Resources Text inherits behavior and resources from the following superclasses. For a complete description of each resource, refer to the man page for that superclass. XmPrimitive Resource Set Class: XmCBottomShadowColor Default: dynamic Type: Pixel Access: CSG Class: XmCBottomShadowPixmap Default: XmUNSPECIFIED_PIXMAP Type: Pixmap Access: CSG Class: XmCForeground Default: dynamic Type: Pixel Access: CSG Class: XmCCallback Default: NULL Type: XtCallbackList Ac- cess: C Class: XmCHighlightColor Default: dynamic Type: Pixel Access: CSG Class: XmCHighlightOnEnter Default: False Type: Boolean Access: CSG Class: XmCHighlightPixmap Default: dynamic Type: Pixmap Access: CSG Class: XmCHighlightThickness Default: 2 Type: Dimension Access: CSG Class: XmCNavigationType Default: XmTAB_GROUP Type: XmNavigation- Type Access: CSG Class: XmCShadowThickness Default: 2 Type: Dimension Access: CSG Class: XmCTopShadowColor Default: dynamic Type: Pixel Ac- cess: CSG Class: XmCTopShadowPixmap Default: dynamic Type: Pixmap Ac- cess: CSG Class: XmCTraversalOn Default: True Type: Boolean Access: CSG Class: XmCUnitType Default: dynamic Type: unsigned char Access: CSG Class: XmCUserData Default: NULL Type: XtPointer Access: CSG Core Resource Set Class: XmCAccelerators Default: dynamic Type: XtAccelerators Access: CSG Class: XmCSensitive Default: dynamic Type: Boolean Access: G Class: XmCBackground Default: dynamic Type: Pixel Access: CSG Class: XmCPixmap Default: XmUNSPECIFIED_PIXMAP Type: Pixmap Access: CSG Class: XmCBorderColor Default: XtDefaultForeground Type: Pixel Access: CSG Class: XmCPixmap Default: XmUNSPECIFIED_PIXMAP Type: Pixmap Ac- cess: CSG Class: XmCBorderWidth Default: 0 Type: Dimension Access: CSG Class: XmCColormap Default: dynamic Type: Colormap Access: CG Class: XmCDepth Default: dynamic Type: int Access: CG Class: XmCCallback De- fault: NULL Type: XtCallbackList Access: C Class: XmCHeight Default: dynamic Type: Dimension Access: CSG Class: XmCInitialResourcesPersis- tent Default: True Type: Boolean Access: C Class: XmCMappedWhenManaged Default: True Type: Boolean Access: CSG Class: XmCScreen Default: dy- namic Type: Screen * Access: CG Class: XmCSensitive Default: True Type: Boolean Access: CSG Class: XmCTranslations Default: dynamic Type: XtTranslations Access: CSG Class: XmCWidth Default: dynamic Type: Dimension Access: CSG Class: XmCPosition Default: 0 Type: Posi- tion Access: CSG Class: XmCPosition Default: 0 Type: Position Access: CSG Callback Information A pointer to the following structure is passed to each callback: type- def struct { int reason; XEvent * event; } XmAnyCallbackStruct; Indicates why the callback was invoked Points to the XEvent that trig- gered the callback The Text widget defines a new callback structure for use with verifica- tion callbacks. Note that not all fields are relevant for every call- back reason. The application must first look at the reason field and use only the structure members that are valid for the particular rea- son. The values startPos, endPos, and text in the callback structure XmTextVerifyCallbackStruct may be modified upon receiving the callback, and these changes will be reflected as the change made to the source of the Text widget. (For example, all keystrokes can be converted to spaces or NULL characters when a password is entered into a Text wid- get.) The application programmer should not overwrite the text field, but should attach data to that pointer. A pointer to the following structure is passed to callbacks for XmNlos- ingFocusCallback, XmNmodifyVerifyCallback, and XmNmotionVerifyCallback. typedef struct { int reason; XEvent * event; Boolean doit; XmTextPosition currInsert, newInsert; XmTextPosition startPos, endPos; XmTextBlock text; } XmTextVerifyCallbackStruct, *XmTextVerifyPtr; Indicates why the callback was invoked. Points to the XEvent that triggered the callback. It can be NULL. For example, changes made to the Text widget programmatically do not have an event that can be passed to the associated callback. Indicates whether the action that invoked the callback is performed. Setting doit to False negates the action. Indicates the current position of the insert cursor. Indi- cates the position at which the user attempts to position the insert cursor. Indicates the starting position of the text to modify. If the callback is not a modify verification callback, this value is the same as currInsert. Indicates the ending position of the text to modify. If no text is replaced or deleted, the value is the same as startPos. If the callback is not a modify verification callback, this value is the same as currInsert. Points to a structure of type XmTextBlockRec. This structure holds the textual information to be inserted. typedef struct { char *ptr; int length; XmTextFormat format; } XmTextBlockRec, *XmTextBlock; Points to the text to be inserted. Specifies the length of the text to be inserted. Specifies the format of the text, either XmFMT_8_BIT or XmFMT_16_BIT. A pointer to the following structure is passed to callbacks for XmNmod- ifyVerifyCallbackWcs. typedef struct { int reason; XEvent *event; Boolean doit; XmTextPosition currInsert, newInsert; XmTextPosition startPos, endPos; XmTextBlockWcs text; } XmTextVerifyCallbackStructWcs, *XmTextVerifyP- trWcs; Indicates why the callback was invoked. Points to the XEvent that triggered the callback. It can be NULL. For example, changes made to the Text widget programmatically do not have an event that can be passed to the associated callback. Indicates whether the action that invoked the callback is performed. Setting doit to False negates the action. Indicates the current position of the insert cursor. Indi- cates the position at which the user attempts to position the insert cursor. Indicates the starting position of the text to modify. If the callback is not a modify verification callback, this value is the same as currInsert. Indicates the ending position of the text to modify. If no text is replaced or deleted, the value is the same as startPos. If the callback is not a modify verification callback, this value is the same as currInsert. Points to a structure of type XmTextBlock- RecWcs. This structure holds the textual information to be inserted. typedef struct { wchar_t *wcsptr; int length; } XmTextBlockRecWcs, *XmTextBlockWcs; Points to the wide character text to be inserted. Specifies the number of characters to be inserted. The following table describes the reasons why the individual verifica- tion callback structure fields are valid: l lw(3.7i). _ Reason Valid Fields _ XmCR_LOSING_FOCUS T{ reason, event, doit, currInsert, newInsert, startPos, endPos T} XmCR_MODIFY- ING_TEXT_VALUE T{ reason, event, doit, currInsert, newInsert, startPos, endPos, text T} XmCR_MOVING_INSERT_CURSOR T{ reason, event, doit, currInsert, newInsert T} _ Translations XmText includes translations from XmPrimitive. The XmText translations are listed below. These translations may not directly correspond to a translation table.

If the parent is a manager, passes the event to the parent. Moves the insertion cursor one character to the left. For other effects, see the description of navigation operations in the "Keyboard Selection" section. This action may have different behavior in a right-to-left language environment. If XmNeditMode is Xm- MULTI_LINE_EDIT and this action is called with no argument, moves the insertion cursor to the first non-whitespace character following the first previous blank line or beginning of the text. If the insertion cursor is already at the beginning of a paragraph, moves the insertion cursor to the beginning of the previous paragraph. For other effects, see the description of navigation operations in the "Keyboard Selec- tion" section. If XmNeditMode is XmMULTI_LINE_EDIT and this action is called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation operations in the "Keyboard Selection" section. If this action is called with no argument, moves the insertion cursor to the first non-white- space character after the first whitespace character to the left or after the beginning of the line. If the insertion cursor is already at the beginning of a word, moves the insertion cursor to the beginning of the previous word. For other effects, see the description of navigation operations in the "Keyboard Selec- tion" section. This action may have different behavior in a lo- cale other than the C locale. If called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation op- erations in the "Keyboard Selection" section. Causes the termi- nal to beep. If this action is called with no argument, moves the insertion cursor to the beginning of the text. For other ef- fects, see the description of navigation operations in the "Key- board Selection" section. If called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation op- erations in the "Keyboard Selection" section. If this action is called with no argument, moves the insertion cursor to the be- ginning of the line. For other effects, see the description of navigation operations in the "Keyboard Selection" section. If called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation op- erations in the "Keyboard Selection" section. Clears the cur- rent selection by replacing each character except <Return> with a <space> character. Copies the current selection to the clip- board. Copies the primary selection to just before the inser- tion cursor. If a secondary selection exists, copies the sec- ondary selection to just before the insertion cursor. If no sec- ondary selection exists, copies the primary selection to the pointer location. Cuts the current selection to the clipboard. Cuts the primary selection to just before the insertion cursor. In normal mode if there is a non-null selection, deletes the se- lection, otherwise deletes the character following the insertion cursor. In add mode if there is a non-null selection, the cur- sor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise deletes the char- acter following the insertion cursor. This may impact the selec- tion. In normal mode if there is a non-null selection, deletes the selection, otherwise deletes the characters following the insertion cursor to the next space, tab or end of line charac- ter. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise deletes the characters following the insertion cursor to the next space, tab or end of line character. This may impact the selection. This action may have different behavior in a locale other than the C locale. In normal mode if there is a non-null selection, deletes the selec- tion, otherwise deletes the character of text immediately pre- ceding the insertion cursor. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and Xm- NpendingDelete is set to True, deletes the selection, otherwise deletes the character of text immediately preceding the inser- tion cursor. This may impact the selection. In normal mode if there is a non-null selection, deletes the selection, otherwise deletes the characters preceding the insertion cursor to the next space, tab or beginning of the line character. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise deletes the characters preceding the insertion cursor to the next space, tab or beginning of line character. This may impact the selection. This action may have different behavior in a locale other than the C locale. Deletes the current selection. In normal mode if there is a non-null selection, deletes the selection, otherwise deletes the charac- ters following the insertion cursor to the next end of line character. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise deletes the characters following the insertion cursor to the next end of line character. This may impact the selection. In normal mode if there is a non-null selection, deletes the selection, other- wise deletes the characters preceding the insertion cursor to the previous beginning of line character. In add mode if there is a non-null selection, the cursor is not disjoint from the se- lection and XmNpendingDelete is set to True, deletes the selec- tion, otherwise deletes the characters preceding the insertion cursor to the previous beginning of line character. This may im- pact the selection. Deselects the current selection. If this action is called with no argument, moves the insertion cursor to the end of the text. For other effects, see the description of navigation operations in the "Keyboard Selection" section. If called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation op- erations in the "Keyboard Selection" section. If this action is called with no argument, moves the insertion cursor to the end of the line. For other effects, see the description of naviga- tion operations in the "Keyboard Selection" section. If called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation op- erations in the "Keyboard Selection" section. Selects text from the anchor to the pointer position and deselects text outside that range. Moving the pointer over several lines selects text from the anchor to the end of each line the pointer moves over and up to the pointer position on the current line. Moves the insertion cursor to the position of the pointer. Adjusts the anchor using the balance-beam method. Selects text from the an- chor to the pointer position and deselects text outside that range. Moves the insertion cursor one character to the right. For other effects, see the description of navigation operations in the "Keyboard Selection" section. This action may have dif- ferent behavior in a right-to-left language environment. If XmNeditMode is XmMULTI_LINE_EDIT, and this action is called with no argument, moves the insertion cursor to the first non-white- space character following the next blank line. If the insertion cursor is already at the beginning of a paragraph, moves the in- sertion cursor to the beginning of the next paragraph. For other effects, see the description of navigation operations in the "Keyboard Selection" section. If XmNeditMode is XmMULTI_LINE_EDIT and this action is called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation operations in the "Keyboard Selection" section. If this action is called with no argument, moves the insertion cursor to the first whitespace character or end of line following the next non-whitespace char- acter. If the insertion cursor is already at the end of a word, moves the insertion cursor to the end of the next word. For other effects, see the description of navigation operations in the "Keyboard Selection" section. This action may have different behavior in a locale other than the C locale. If called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation op- erations in the "Keyboard Selection" section. This key binding performs the action defined in the XmNselectionArray, depending on the number of multiple mouse clicks. The default selection array ordering is one click to move the insertion cursor to the pointer position, two clicks to select a word, three clicks to select a line of text, and four clicks to select all text. A single click also deselects any selected text and sets the an- chor at the pointer position. This action may have different be- havior in a locale other than the C locale. Calls the callbacks for XmNhelpCallback if any exist. If there are no help callbacks for this widget, this action calls the help callbacks for the nearest ancestor that has them. If XmNpendingDelete is True and the cursor is not disjoint from the current selection, deletes the entire selection. Inserts string before the insertion cur- sor. If called with an argument of right, moves the insertion cursor one character to the right and extends the current selec- tion. If called with an argument of left, moves the insertion cursor one character to the left and extends the current selec- tion. If called with no argument, extends the current selection. For other effects, see the description of shifted navigation op- erations and KExtend in the "Keyboard Selection" section. In normal mode if there is a non-null selection, deletes the selec- tion, otherwise kills the character following the insertion cur- sor and stores the character in the cut buffer. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise kills the character following the insertion cursor and stores the character in the cut buffer. This may im- pact the selection. In normal mode if there is a non-null se- lection, deletes the selection, otherwise kills the characters following the insertion cursor to the next space, tab or end of line character, and stores the characters in the cut buffer. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise kills the characters following the insertion cursor to the next space, tab or end of line char- acter, and stores the characters in the cut buffer. This may im- pact the selection. This action may have different behavior in a locale other than the C locale. In normal mode if there is a non-null selection, deletes the selection, otherwise kills the character immediately preceding the insertion cursor and stores the character in the cut buffer. In add mode if there is a non- null selection, the cursor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, oth- erwise kills the character immediately preceding the insertion cursor and stores the character in the cut buffer. This may im- pact the selection. In normal mode if there is a non-null se- lection, deletes the selection, otherwise kills the characters preceding the insertion cursor up to the next space, tab or be- ginning of line character, and stores the characters in the cut buffer. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise kills the characters preceding the insertion cursor up to the next space, tab or be- ginning of line character, and stores the characters in the cut buffer. This may impact the selection. This action may have dif- ferent behavior in a locale other than the C locale. Kills the currently selected text and stores the text in the cut buffer. In normal mode if there is a non-null selection, deletes the se- lection, otherwise kills the characters following the insertion cursor to the next end of line character and stores the charac- ters in the cut buffer. In add mode if there is a non-null se- lection, the cursor is not disjoint from the selection and XmN- pendingDelete is set to True, deletes the selection, otherwise kills the characters following the insertion cursor to the next end of line character and stores the characters in the cut buffer. This may impact the selection. In normal mode if there is a non-null selection, deletes the selection, otherwise kills the characters preceding the insertion cursor to the next begin- ning of line character and stores the characters in the cut buffer. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise kills the characters preceding the insertion cursor to the next beginning of line character and stores the characters in the cut buffer. This may impact the selection. Moves the insertion cursor to the pointer position without changing any existing current selection. If there is no current selection, sets the widget as the destina- tion widget. If a secondary selection exists, cuts the sec- ondary selection to the insertion cursor. If no secondary selec- tion exists, cuts the primary selection to the pointer location. If XmNpendingDelete is True and the cursor is not disjoint from the current selection, deletes the entire selection. Inserts a newline before the insertion cursor. If XmNpendingDelete is True and the cursor is not disjoint from the current selection, deletes the entire selection. Inserts a newline just before the insertion cursor and repositions the insertion cursor to the end of the line before the newline. If XmNpendingDelete is True and the cursor is not disjoint from the current selection, deletes the entire selection. Inserts a newline and then the same number of whitespace characters as at the beginning of the previous line. Moves the insertion cursor to the next line. For other effects, see the description of navigation operations in the "Keyboard Selection" section. If this action is called with no argument, moves the insertion cursor forward one page. For other effects, see the description of navigation operations in the "Keyboard Selection" section. If called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation op- erations in the "Keyboard Selection" section. Traverses to the next tab group. Scrolls the viewing window left one page of text. Scrolls the viewing window right one page of text. Pastes the contents of the clipboard before the insertion cur- sor. Traverses to the previous tab group. Moves the insertion cursor to the previous line. For other effects, see the descrip- tion of navigation operations in the "Keyboard Selection" sec- tion. If this action is called with no argument, moves the in- sertion cursor back one page. For other effects, see the de- scription of navigation operations in the "Keyboard Selection" section. If called with an argument of extend, moves the insertion cursor as in the case of no argument and extends the current selection. For other effects, see the description of shifted navigation op- erations in the "Keyboard Selection" section. The result of this action is determined by several factors: position of the location cursor, movement of the location cursor, and the inter- val between a BDrag press and release. This action copies the current selection to the insertion cursor if text is selected, the location cursor is disjoint from the current selection, and no motion is detected within a given time interval. It performs a secondary selection and copies the selection to the position where the text was last edited if the cursor is disjoint from a current selection (if one exists), the time in- terval is exceeded, and movement of the location cursor is de- tected. The action drags the current selection if the location cursor is positioned on the selection, the time interval is exceeded, and movement of the location cursor is detected. This action cre- ates a DragContext object whose XmNexportTargets resource value includes target types of COMPOUND_TEXT, STRING, and TEXT. Can- cels the current extend-adjust(), secondary-adjust() or process- bdrag() operation and leaves the selection state as it was be- fore the operation, otherwise, and if the parent is a manager, passes the event to the parent. If XmNeditMode is XmSIN- GLE_LINE_EDIT and XmNnavigationType is XmNONE, traverses to the widget below the current one in the tab group. If XmNeditMode is XmMULTI_LINE_EDIT, moves the insertion cursor down one line. For other effects, see the description of naviga- tion operations in the "Keyboard Selection" section. Moves the insertion cursor to the beginning of the line. For other ef- fects, see the description of navigation operations in the "Key- board Selection" section. If XmNeditMode is XmSINGLE_LINE_EDIT, calls the callbacks for XmNactivateCallback, and if the parent is a manager, passes the event to the parent. If XmNeditMode is XmMULTI_LINE_EDIT, inserts a newline. If XmNeditMode is Xm- MULTI_LINE_EDIT, moves the insertion cursor down one line. For other effects, see the description of navigation operations in the "Keyboard Selection" section. If XmNeditMode is Xm- MULTI_LINE_EDIT, moves the insertion cursor up one line. For other effects, see the description of navigation operations in the "Keyboard Selection" section. If XmNeditMode is XmSIN- GLE_LINE_EDIT, traverses to the next tab group. If XmNeditMode is XmMULTI_LINE_EDIT, inserts a tab. If XmNeditMode is XmSIN- GLE_LINE_EDIT and XmNnavigationType is XmNONE, traverses to the widget above the current one in the tab group. If XmNeditMode is XmMULTI_LINE_EDIT, moves the insertion cursor up one line. For other effects, see the description of naviga- tion operations in the "Keyboard Selection" section. Redraws the contents of the text window. Scrolls the line containing the insertion cursor vertically to an intermediate position in the visible window based on an input percentage. A value of 0 indicates the top of the window; a value of 100, the bottom of the window. If this action is called with no argument, the line containing the insertion cursor is scrolled vertically to a new position designated by the y position of the event passed to the routine. Scrolls the text area down one line. Scrolls the text area up one line. Extends the secondary selection to the pointer position. Copies the secondary selection to the inser- tion cursor of the destination widget. Marks the beginning of a secondary selection. Extends the current selection. The amount of text selected depends on the number of mouse clicks, as spec- ified by the XmNselectionArray resource. Selects all text. Ex- tends the current selection. The amount of text selected depends on the number of mouse clicks, as specified by the XmNselec- tionArray resource. Marks the beginning of a new selection re- gion. If XmNpendingDelete is True and the cursor is not dis- joint from the current selection, deletes the entire selection. Inserts the character associated with the key pressed at the in- sertion cursor. Resets the anchor point for extended selec- tions. Resets the destination of secondary selection actions. Sets the insertion position. Sets the text source and location of the current selection. Toggles the state of Add Mode. Tog- gles the state of the text insertion mode. By default, charac- ters typed into the Text widget are inserted at the position of the insertion cursor. In overstrike mode, characters entered into the Text widget replace the characters that directly follow the insertion cursor. In overstrike mode, when the end of a line is reached, characters are appended to the end of the line. Traverses to the first widget in the tab group. Traverses to the next widget in the tab group. Traverses to the previous widget in the tab group. Restores last killed text to the posi- tion of the insertion cursor. Additional Behavior This widget has the additional behavior described below: Draws the in- sertion cursor as solid and starts blinking the cursor. Displays the insertion cursor as a stippled I-beam unless it is the destination wid- get. Virtual Bindings The bindings for virtual keys are vendor specific.
