XmTextField(3X) XmTextField(3X) NAME XmTextField - The TextField class SYNOPSIS #include <Xm/TextF.h> DESCRIPTION TextField widget provides a single line text editor for customizing both user and programmatic interfaces. It is used for single-line string entry, and forms entry with verification procedures. It provides an application with a consistent editing system for textual data. TextField widget provides separate callback lists to verify movement of the insert cursor, modification of the text, and changes in input fo- cus. Each of these callbacks provides the verification function with the widget instance, the event that caused the callback, and a data structure specific to the verification type. From this information the function can verify if the application considers this to be a legiti- mate state change and can signal the widget whether to continue with the action. The user interface tailors a new set of actions. The key bindings have been added for insert cursor movement, deletion, insertion, and selec- tion of text. TextField allows the user to select regions of text. Selection is based on the model specified in the Inter-Client Communication Conventions Manual (ICCCM). TextField supports primary and secondary selection. Classes TextField widget inherits behavior and resources from Core and Primi- tive classes. The class pointer is xmTextFieldWidgetClass. The class name is XmTextField. 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 lower case or upper case, but include any underscores between words). The codes in the ac- cess 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. Specifies the blink rate of the text cursor in milliseconds. The time indicated in the blink rate relates to the length of time the cursor is visible and the time the cursor is invisible (i.e., the time it will take to blink the insertion cursor on and off will be 2 times the blink rate). The cursor will 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 associ- ated 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. In- dicates 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. Indicates that the insert cursor position is marked by a blinking text cursor when the Boolean is True. Indi- cates that the user can edit the text string when set to True. A false value will prohibit the user from editing the text. Specifies the list of callbacks called when TextField accepts input focus. The type of the structure whose address is passed to this callback is XmAnyCall- backStruct. The reason sent by the callback is XmCR_FOCUS. Specifies the font list to be used for TextField. If this value is NULL at ini- tialization, it is initialized by looking up the parent hierarchy of the widget for an ancestor that is a subclass of the XmBulletinBoard or VendorShell 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 dependent. Refer to XmFontList(3X) for more information on a font list structure. TextField searches the font list for the first occurrence of a font set that has a XmFONTLIST_DEFAULT_TAG. If a default ele- ment 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 is used. Specifies the list of callbacks that are called when the user invokes an event that cause the text widget to gain ownership of the primary selection. The callback reason for this callback is XmCR_GAIN_PRIMARY. Specifies the list of call- backs that are called when the user invokes an event that cause the text widget to lose ownership of the primary selection. The callback reason for this callback is XmCR_LOSE_PRIMARY. Speci- fies the list of callbacks that is called before TextField wid- get 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 the bottom edge of the widget window and the text. Speci- fies the distance between the left edge of the widget window and the text, and the right edge of the widget window and the text. Specifies the maximum length of the text string that can be en- tered into text from the keyboard. This value must be non-nega- tive. Strings that are entered using the XmNvalue resource or the XmTextFieldSetString() function ignore this resource. Spec- ifies the list of callbacks that is called before text is deleted from or inserted into TextField. The type of the struc- ture whose address is passed to this callback is XmTextVerify- CallbackStruct. The reason sent by the callback is XmCR_MODIFY- ING_TEXT_VALUE. When multiple TextField widgets share the same source, only the widget that initiates the source change will generate the XmNmodifyVerifyCallback. 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 TextField widgets share the same source, only the widget that initiates the source change will generate the XmNmodifyVerify- CallbackWcs. 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 that is called before the insert cursor is moved to a new position. 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 more than one XmNmotionVerifyCallbacks to be generated from a single action. Indicates that pending delete mode is on when the Boolean is True. Pending deletion is defined as deletion of the selected text when an insertion is made. Indicates that TextField widget will attempt to resize its width to accommodate all the text contained in the widget when Boolean is True. De- fines the actions for multiple-mouse clicks. Each mouse click performed within a half of a second of the previous mouse click will increment the index into this array and perform the defined action for that index. The possible actions are: XmSELECT_POSI- TION--resets the insert cursor position. XmSELECT_WORD--selects a word. XmSELECT_LINE--selects a line of text. Specifies the number of actions that are defined in the XmNselectionArray re- source. The value must not be negative. Specifies the number of pixels of motion that is required to select the next character when selection is performed using the click-drag mode of selec- tion. The value must not be negative. Specifies the string value of the TextField widget as a char* data value. If 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 that is called after text is deleted from or inserted into TextField. The type of the structure whose address is passed to this callback is XmAnyCallbackStruct. The reason sent by the callback is XmCR_VALUE_CHANGED. When multiple TextField 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 TextField, not in the TextField widget. The XmNvalueChangedCallback should occur only in pairs with a XmNmodifyVerifyCallback, assuming that the doit flag in the callback structure of the XmNmodifyVerifyCallback is not set to False. Specifies the string value of the TextField widget as a wchar_t* data value. This resource cannot be speci- fied in a resource 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 a bell will sound when an action is reversed during a verification callback. The default depends on the value of the ancestor VendorShell's XmNaudibleWarning resource. Inherited Resources TextField widget inherits behavior and resources from the following su- perclasses. For a complete description of these resources, refer to the man page for that superclass.

Points to the XEvent that triggered the callback. The TextField widget defines a new callback structure for use with ver- ification callbacks. Note that not all of the fields are relevant for every callback reason. The application must first look at the reason field and use only the structure members that are valid for the partic- ular reason. 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 TextField widget. (For example, all keystrokes can be converted to spaces or NULL characters when a password is entered into a TextField widget.) 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 the callbacks for XmNlosingFocusCallback, XmNmodifyVerifyCallback, and XmNmotionVerify- Callback. 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 that action that invoked the callback will be performed. Setting doit to False negates the action. Indicates the current position of the insert cursor. In- dicates 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, then the value is the same as start- Pos. If the callback is not a modify verification callback, this value is the same as currInsert. Points to a structure of type XmTextBlock- Rec. This structure holds the textual information to be inserted. typedef struct { char *ptr; int length; XmTextFormat format } XmTextBlockRec, *XmTextBlock; Is the text to be inserted. ptr points to a temporary storage space that is reused after the callback is finished. Therefore, if an appli- cation needs to save the text to be inserted, it should copy the text into its own data space. Specifies the length of the text to be in- serted. 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; XmWcsTextBlock 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 for which the individual ver- ification callback structure fields are valid: l lw(3.7i). _ Reason Valid Fields _ XmCR_LOSING_FOCUS reason, event, doit XmCR_MODIFYING_TEXT_VALUE T{ reason, event, doit, cur- rInsert, newInsert, startPos, endPos, text T} XmCR_MOVING_INSERT_CUR- SOR T{ reason, event, doit, currInsert, newInsert T} _ Translations XmTextField includes translations from XmPrimitive.

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 in XmText(3X). This action may have dif- ferent behavior in a right-to-left language environment. If this ac- tion is called with no argument, moves the insertion cursor to the first non-whitespace 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 Selection" section in Xm- Text(3X). 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 in XmText(3X). If this action is called with no argument, moves the insertion cur- sor to the beginning of the line. For other effects, see the de- scription of navigation operations in the "Keyboard Selection" section in XmText(3X). 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 in XmText(3X). Clears the current selection by replacing each character except <Return> with a <space> character. Copies the current selection to the clipboard. Copies the primary selection to just before the insertion cursor. If a secondary selection exists, copies the secondary selection to just before the insertion cursor. If no secondary selection exists, copies the primary selection to the pointer location. Cuts the current selection to the clip- board. Cuts the primary selection to just before the insertion cursor. In normal mode if there is a non-null selection, deletes the selection, otherwise deletes the character following the insertion cursor. In add mode if there is a non-null selec- tion, the cursor is not disjoint from the selection and XmNpend- ingDelete is set to True, deletes the selection, otherwise deletes the character following the insertion cursor. This may impact the selection. In normal mode if there is a non-null se- lection, deletes the selection, otherwise deletes the characters following the insertion cursor to the next space, tab or end of line character. In add mode if there is a non-null selection, the cursor is not disjoint from the selection and XmNpend- ingDelete 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 selection, otherwise deletes the charac- ter of text immediately preceding the insertion cursor. In add mode if there is a non-null selection, the cursor is not dis- joint from the selection and XmNpendingDelete is set to True, deletes the selection, otherwise deletes the character of text immediately preceding the insertion cursor. This may impact the selection. In normal mode if there is a non-null selection, deletes the selection, otherwise deletes the characters preced- ing the insertion cursor to the next space, tab or beginning of the line character. In add mode if there is a non-null selec- tion, the cursor is not disjoint from the selection and XmNpend- ingDelete 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 lo- cale other than the C locale. Deletes the current selection. In normal mode if there is a non-null selection, deletes the se- lection, otherwise deletes the characters following the inser- tion 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 inser- tion 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, otherwise deletes the characters preced- ing the insertion cursor to the previous beginning of line char- acter. 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 previous beginning of line character. This may impact the selection. Deselects the current selection. 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 navigation operations in the "Keyboard Selec- tion" section in XmText(3X). If called with an argument of ex- tend, 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 in XmText(3X). Selects text from the anchor to the pointer position and deselects text outside that range. Moves the insertion cursor to the position of the pointer. Ad- justs the anchor using the balance-beam method. Selects text from the anchor to the pointer position and deselects text out- side 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 in XmText(3X). This action may have different behavior in a right-to-left lan- guage environment. 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 character. If the insertion cursor is already at the end of a word, moves the in- sertion cursor to the end of the next word. For other effects, see the description of navigation operations in the "Keyboard Selection" section in XmText(3X). 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 ef- fects, see the description of shifted navigation operations in the "Keyboard Selection" section in XmText(3X). This key bind- ing performs the action defined in the XmNselectionArray, de- pending on the number of multiple mouse clicks. The default se- lection 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 anchor at the pointer position. This action may have differ- ent behavior 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 called with an argu- ment of right, moves the insertion cursor one character to the right and extends the current selection. If called with an ar- gument of left, moves the insertion cursor one character to the left and extends the current selection. If called with no argu- ment, extends the current selection. For other effects, see the description of shifted navigation operations and KExtend in the "Keyboard Selection" section in XmText(3X). 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 destination widget. If a secondary selection ex- ists, cuts the secondary selection to just before the insertion cursor. If no secondary selection exists, cuts the primary se- lection to the pointer location. 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 cursor. Tra- verses to the previous tab group. The result of this action is determined by several factors: position of the location cursor, movement of the location cursor, and the interval 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 selection, and no motion is detected within a given time inter- val. 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 before the operation, otherwise, and the parent is a manager, it passes the event to the parent. Extends the secondary selection to the pointer position. Marks the beginning of a secondary selection. Selects all text. If XmNpendingDelete is True and the cursor is not disjoint from the current selection, deletes the entire se- lection. Inserts the character associated with the key pressed before the insertion cursor. Resets the anchor point for ex- tended selections. Resets the destination of secondary selec- tion actions. Toggles the state of Add Mode. Toggles the state of the text insertion mode. By default, characters typed into the TextField widget are inserted before the position of the in- sertion cursor. In overstrike mode, characters entered into the TextField 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. Tra- verses 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. 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. The following table lists the TextField-specific bindings of virtual keys to actual key event descriptions in 1/Motif: l s l l. _ Virtual Key Bindings Valid Fields Virtual Key Actual Key Events _ KExtend Ctrl Shift<Key>space Shift<Key>osfSelect KSelect Ctrl<Key>space <Key>osfSelect _ For information about bindings for virtual buttons and keys, see Virtu- alBindings(3X).
