Text <strong>Widget</strong>sextend-start()extend-adjust()extend-end(name[,name,...])This action finds the nearest end of the current selection,and moves it to the current pointer location (iftriggered by a button event) or text cursor location(if triggered by a key event).This action allows a selection started with an extend-startaction to be modified.This action ends a text selection that began with theextend-start action, and asserts ownership of the selectionor selections specified. A name can be a selection(e.g. PRIMARY) or a cut buffer (e.g CUT_BUFFER0).Note that case is important. If no names are given,PRIMARY is asserted.insert-selection(name[,name,...])named selection that exists or the cut buffer that isThis action retrieves the value of the first (left-most)not empty and inserts it into the Text widget at thecurrent insert point location. A name can be a selection(e.g. PRIMARY) or a cut buffer (e.g CUT_BUFFER0).Note that case is important.The New Line Actionsnewline-and-indent()newline-and-backup()newline()Kill and ActionsThis action inserts a newline into the text and addsspaces to that line to indent it to match the previousline.This action inserts a newline into the text after theinsert point.This action inserts a newline into the text before theinsert point.kill-word()backward-kill-word()kill-selection()kill-to-end-of-line()kill-paragraph()These actions act exactly like the delete-nextwordand delete-previous-word actions, but theystuff the word that was killed into the kill buffer(CUT_BUFFER_1).This action deletes the current selection and stuffsthe deleted text into the kill buffer (CUT_BUFFER_1).This action deletes the entire line to the right of theinsert point position, and stuffs the deleted text intothe kill buffer (CUT_BUFFER_1).This action deletes the current paragraph, if betweenparagraphs it deletes the paragraph above the insertpoint, and stuffs the deleted text into the kill buffer(CUT_BUFFER_1).71
Text <strong>Widget</strong>skill-to-end-of-paragraph()Miscellaneous Actionsredraw-display()insert-file([filename])insert-char()insert-string(string[,string,...])display-caret(state,when)This action deletes everything between the currentinsert point location and the next paragraph boundary,and stuffs the deleted text into the kill buffer(CUT_BUFFER_1).This action recomputes the location of all the textlines on the display, scrolls the text to vertically centerthe line containing the insert point on the screen,clears the entire screen, and redisplays it.This action activates the insert file popup. The filenameoption specifies the default filename to put inthe filename buffer of the popup. If no filename isspecified the buffer is empty at startup.This action may only be attached to a key event.When the international resource is false, this actioncalls XLookupString to translate the event intoa (rebindable) Latin-1 character (sequence) and insertsit into the text at the insert point. When the internationalresource is true, characters are passedto the input method via XwcLookupString, and anycommitted string returned is inserted into the text atthe insert point.This action inserts each string into the text at theinsert point location. Any string beginning with thecharacters "0x" followed by an even number of hexadecimaldigits is interpreted as a hexadecimal constantand the corresponding string is inserted instead.This hexadecimal string may represent upto 50 8-bit characters. When theinternational resourceis true, a hexadecimal string is intrepeted asbeing in a multi-byte encoding, and a hexadecimal orregular string will result in an error message if it isnot legal in the current locale.This action allows the insert point to be turned on andoff. The state argument specifies the desired state ofthe insert point. This value may be any of the stringvalues accepted for Boolean resources (e.g. on, True,off, False, etc.). If no arguments are specified, thedefault value is True. The when argument specifies,for EnterNotify or LeaveNotify events whether ornot the focus field in the event is to be examined.If the second argument is not specified, or specifiedas something other than always then if the action isbound to an EnterNotify or LeaveNotify event, theaction will be taken only if the focus field is True. Anaugmented binding that might be useful is:72
