Keep in mind thatthe SimpleMenu widget will force all menu items to be the width of thewidest entry. Thus, setting the width is generally not very important.The width of the horizontal line that is to be displayed.If a bitmap is specified for this resource, the line will be stippledthrough it. This allows the menu separator to be rendered as somethingmore exciting than just a line. For instance, if you define a stipplethat is a chain link, then your menu separators will look like chains.63
Chapter 5. Text WidgetsThe Text widget provides a window that will allow an application to display and editone or more lines of text. Options are provided to allow the user to add Scrollbarsto its window, search for a specific string, and modify the text in the buffer.The Text widget is made up of a number of pieces; it was modularized to ease customization.The AsciiText widget class (actually not limited to ASCII but so namedfor compatibility) is be general enough to most needs. If more flexibility, specialfeatures, or extra functionality is needed, they can be added by implementing a newTextSource or TextSink, or by subclassing the Text Widget (See Section 5.8 for customizationdetails.)The words insertion point are used in this chapter to refer to the text caret. This isthe symbol that is displayed between two characters in the file. The insertion pointmarks the location where any new characters will be added to the file. To avoidconfusion the pointer cursor will always be referred to as the pointer.The text widget supports three edit modes, controlling the types of modificationsa user is allowed to make:• Append-only• Editable• Read-onlyRead-only mode does not allow the user or the programmer to modify the text in thewidget. While the entire string may be reset in read-only mode with XtSetValues,it cannot be modified via with XawTextReplace. Append-only and editable modesallow the text at the insertion point to be modified. The only difference is that textmay only be added to or removed from the end of a buffer in append-only mode.Text Widget for UsersThe Text widget provides many of the common keyboard editing commands. Thesecommands allow users to move around and edit the buffer. If an illegal operationis attempted, (such as deleting characters in a read-only text widget), the X serverwill beep.Default Key BindingsThe default key bindings are patterned after those in the EMACS text editor:Ctrl-a Beginning Of Line Meta-b Backward WordCtrl-b Backward Character Meta-f Forward WordCtrl-d Delete Next Character Meta-i Insert FileCtrl-e End Of Line Meta-k Kill To End Of ParagraphCtrl-f Forward Character Meta-q Form ParagraphCtrl-g Multiply Reset Meta-v Previous Page64
