editres(1X) editres(1X) NAME editres - a dynamic resource editor for X Toolkit applications SYNOPSIS editres [-toolkitoption...] OPTIONS The editres command accepts all of the standard X Toolkit command line options (see X(1X)). The order of the command line options is not im- portant. DESCRIPTION editres is a tool that allows users and application developers to view the full widget hierarchy of any X Toolkit application that speaks the editres protocol. In addition editres will help the user construct re- source specifications, allow the user to apply the resource to the ap- plication and view the results dynamically. Once the user is happy with a resource specification editres will append the resource string to the user's X Resources file. USING EDITRES Editres provides a window consisting of the following four areas: A set of popup menus that allow you full access to editres's features. The panner allows a more intuitive way to scroll the application tree dis- play. Displays information to the user about the action that editres expects of her. This area will be used to display the selected appli- cation's widget tree. To begin an editres session select the Get Widget Tree menu item from the command menu. This will change the pointer cursor to cross hair. You should now select the application you wish look at by clicking on any of its windows. If this application understands the editres proto- col then editres will display the application's widget tree in its tree window. If the application does not understand the editres protocol editres will inform you of this fact in the message area after a few seconds delay. Once you have a widget tree you may now select any of the other menu options. The effect of each of these is described below. COMMANDS Allows the user to click on any application that speaks the editres protocol and receive its widget tree. Editres only knows about the widgets that exist at the present time. Many applications create and destroy widgets on the fly. Selecting this menu item will cause ed- itres to ask the application to resend its widget tree, thus updating its information to the new state of the application. For example, xman only creates the widgets for its topbox when it starts up. None of the widgets for the manual page window are created until the user actually clicks on the Manual Page button. If you retrieved xman's widget tree before the manual page is active, you may wish to refresh the widget tree after the manual page has been displayed. This will allow you to also edit the manual page's resources. For documenting applications it is often useful to be able to dump the entire application widget tree to an ASCII file. This file can then be included in the manual page. When this menu item is selected a popup dialog is activated. Type the name of the file in this dialog, and ei- ther select okay, or type a carriage-return. Editres will now dump the widget tree to this file. To cancel the file dialog, select the cancel button. This command will popup a resource box for the current application. This resource box (described in detail below) will allow the user to see exactly which re- sources can be set for the widget that is currently selected in the widget tree display. Only one widget may be currently se- lected; if greater or fewer are selected editres will refuse to pop up the resource box and put an error message in the Message Area. This command will popup a simple dialog box for setting an arbitrary resource on all selected widgets. You must type in the resource name, as well as the value. You can use the Tab key to switch between the resource name field the resource value field. Exits editres. TREE COMMANDS The Tree menu contains several commands that allow operations to be performed on the widget tree. This menu item allows you to select any widget in the application; editres will then highlight the correspond- ing element the widget tree display. Once this menu item is selected the pointer cursor will again turn to a crosshair, and you must click any pointer button in the widget you wish to have displayed. Since some widgets are fully obscured by their children, it is not possible to get to every widget this way, but this mechanism does give very use- ful feedback between the elements in the widget tree and those in the actual application. These functions allow the user to select, unse- lect, or invert all widgets in the widget tree. These functions select the immediate parent or children of each of the currently selected wid- gets. These functions select all parents or children of each of the currently selected widgets. This is a recursive search. When the tree widget is initially displayed the labels of each widget in the tree correspond to the widget names. These functions will cause the label of all widgets in the tree to be changed to show the class name, IDs, or window associated with each widget in the application. The widget IDs, and windows are shown as hex numbers. In the case of 64 bit ad- dressing these hex numbers will only be the lower 32 bits of the wid- get's ID. In addition there are keyboard accelerators for each of the Tree operations. If the input focus is over an individual widget in the tree, then that operation will only effect that widget. If the input focus is in the Tree background it will have exactly the same effect as the corresponding menu item. The translation entries shown may be applied to any widget in the application. If that widget is a child of the Tree widget, then it will only affect that widget, otherwise it will have the same effect as the commands in the tree menu. This command is the inverse of the Select Widget in Client command, it will show the user each widget that is currently selected in the widget tree, by flashing the corresponding widget in the application numFlashes (three by default) times in the flashColor. l l l. _ Key Option Translation Entry _ space Unse- lect Select(nothing) w Select Select(widget) s Select i Invert Select(invert) c Select Children Se- lect(children) d Select Descendants Select(descendants) p Select Parent Select(parent) a Select Ancestors Se- lect(ancestors) N Show Widget Names Relabel(name) C Show Class Names Relabel(class) I Show Widget IDs Rela- bel(id) W Show Widget Windows Relabel(window) T Toggle Widget/Class name Relabel(toggle) _ Clicking button 1 on a widget adds it to the set of selected widgets. Clicking button 2 on a widget deselects all other wid- gets and then selects just that widget. Clicking button 3 on a widget toggles its label between the widget's instance name the widget's class name. USING THE RESOURCE BOX The resource box contains five different areas. Each of the areas, as they appear on the screen, from top to bottom will be discussed. This area at the top of the resource box shows the current resource name ex- actly as it would appear if you were to save it to a file or apply it. This area allows you to select exactly which widgets this resource will apply to. The area contains four lines, the first contains the name of the selected widget and all its ancestors, and the more restrictive dot (.) separator. The second line contains less specific the Class names of each widget, and well as the less restrictive star (*) separator. The third line contains a set of special buttons called Any Widget which will generalize this level to match any widget. The last line contains a set of special buttons called Any Widget Chain which will turn the single level into something that matches zero or more levels. The initial state of this area is the most restrictive, using the resource names and the dot separator. By selecting the other buttons in this area you can ease the restrictions to al- low more and more widgets to match the specification. The ex- treme case is to select all the Any Widget Chain buttons, which will match every widget in the application. As you select dif- ferent buttons the tree display will update to show you exactly which widgets will be effected by the current resource specifi- cation. The next area allows you to select the name of the nor- mal or constraint resources you wish to set. Some widgets may not have constraint resources, so that area will not appear. This next area allows you to enter the resource value. This value should be entered exactly as you would type a line into your resource file. Thus it should contain no unescaped new- lines. There are a few special character sequences for this file: \n -- This will be replaced with a newline. \### -- Where # is any octal digit. This will be replaced with a single byte that contains this sequence interpreted as an oc- tal number. For example, a value containing a NULL byte can be stored by specifying \000. \<new-line> -- This will compress to nothing. \\ -- This will compress to a single backslash. If the client application uses a version of the editres protocol that can provide the current values of the widget's resources to the editres editor, the initial value of the text in the Re- source Value area will be set to a representation of the current value of the resource. Being able to display a meaningful text representation of the value depends on the existence of a converter that can convert from the data type of the resource to a text string. For any resource value that cannot be converted to a text string, the value string will be a decimal integer representation of the value followed by the string (integer fallback conversion). If you enter a new value for this resource, be sure to delete the (integer fallback conversion) string and enter a string value in the appropriate format for conversion to the resource's data type. This area contains several command buttons, described in this section. This button allows the user to modify file that the resources will be saved to. This button will bring up a di- alog box that will ask you for a filename; once the filename has been entered, either hit carriage-return or click on the okay button. To pop down the dialog box without changing the save file, click the cancel button. This button will append the re- source line described above to the end of the current save file. If no save file has been set the Set Save File dialog box will be popped up to prompt the user for a filename. This button at- tempts to perform a XtSetValues call on all widgets that match the resource line described above. The value specified is ap- plied directly to all matching widgets. This behavior is an at- tempt to give a dynamic feel to the resource editor. Since this feature allows users to put an application in states it may not be willing to handle, a hook has been provided to allow specific applications to block these SetValues requests (see Blocking Ed- itres Requests below). Unfortunately due to design constraints imposed on the widgets by the X Toolkit and the Resource Manager, trying to coerce an inherently static system into dynamic behavior can cause strange results. There is no guarantee that the results of an apply will be the same as what will happen when you save the value and restart the application. This functionality is provided to try to give you a rough feel for what your changes will accomplish, and the results obtained should be considered suspect at best. Having said that, this is one of the neatest features of ed- itres, and I strongly suggest that you play with it, and see what it can do. This button combines the Save and Apply actions described above into one button. This button will remove the resource box from the display. BLOCKING EDITRES REQUESTS The editres protocol has been built into the Athena Widget set. This allows all applications that are linked against Xaw to be able to speak to the resource editor. While this provides great flexibility, and is a useful tool, it can quite easily be abused. It is therefore possible for any Xaw application to specify a value for the editresBlock re- source described below, to keep editres from divulging information about its internals, or to disable the SetValues part of the protocol. Specifies which type of blocking this application wishes to impose on the editres protocol. The accepted values are: Block all requests. Block all SetValues re- quests. As this is the only editres request that actually modifies the application, this is in effect stating that the application is read- only. Allow all editres requests. Remember that these resources are set on any Xaw application, not ed- itres. They allow individual applications to keep all or some of the requests editres makes from ever succeeding. Of course, editres is also an Xaw application, so it may also be viewed and modified by ed- itres (rather recursive, I know), these commands can be blocked by set- ting the editresBlock resource on editres itself. RESOURCES For editres the available application resources are: Specifies the num- ber of times the widgets in the application will be flashed when the Show Active Widgets command is invoked. Amount of time between the flashes described above. Specifies the color used to flash application widgets. A bright color should be used that will immediately draw your attention to the area being flashed, such as red or yellow. This is the file the resource line will be append to when the Save button acti- vated in the resource box. WIDGETS In order to specify resources, it is useful to know the hierarchy of the widgets which compose editres. In the notation below, indentation indicates hierarchical structure. The widget class name is given first, followed by the widget instance name.

RESTRICTIONS This is a prototype, there are lots of nifty features I would love to add, but I hope this will give you some ideas about what a resource ed- itor can do.
