Text Widgets*Text.Translations: #override \\: display-caret(on) \\n\\: display-caret(off)focus-in()focus-out()search(direction,[string])multiply(value)form-paragraph()transpose-characters()no-op([action])These actions do not currently do anything.This action activates the search popup. The directionmust be specified as either forward or backward. Thestring is optional and is used as an initial value forthe Search for: string. For further explanation of thesearch widget see the section on Text Searches.The multiply action allows the user to multiply theeffects of many of the text actions. Thus the followingaction sequence multiply(10) delete-next-word()will delete 10 words. It does not matter whetherthese actions take place in one event or many events.Using the default translations the key sequence\fIControl-u, Control-d\fP will delete 4 characters.Multiply actions can be chained, thus \fImultiply(5)multiply(5)\fP is the same as multiply(25). If thestring reset is passed to the multiply action the effectsof all previous multiplies are removed and abeep is sent to the display.This action removes all the Carriage Returns fromthe current paragraph and reinserts them so thateach line is as long as possible, while still fitting onthe current screen. Lines are broken at word boundariesif at all possible. This action currently worksonly on Text widgets that use ASCII text.This action will swap the position of the character tothe left of the insert point with the character to theright of the insert point. The insert point will then beadvanced one character.The no-op action makes no change to the text widget,and is mainly used to override translations. This actiontakes one optional argument. If this argument isRingBell then a beep is sent to the display.XawWMProtocols([wm_protocol_name]) This action is written specifically for the file insertionand the search and replace dialog boxes. Thisaction is attached to those shells by the Text widget,in order to handle ClientMessage events withthe WM_PROTOCOLS atom in the detail field. Thisaction supports WM_DELETE_WINDOW on the Textwidget popups, and may support other window managerprotocols if necessary in the future. The popupwill be dismissed if the window manager sendsa WM_DELETE_WINDOW request and there are noparameters in the action call, which is the default.73
Text Widgetsreconnect-im()The popup will also be dismissed if the parameters includethe string ``wm_delete_window,'' and the eventis a ClientMessage event requesting dismissal or isnot a ClientMessage event. This action is not sensitiveto the case of the strings passed as parameters.When the international resource is true, inputis usually passed to an input method, a separateprocess, for composing. Sometimes the connectionto this process gets severed; this action will attemptto reconnect it. Causes for severage include networktrouble, and the user explicitly killing one inputmethod and starting a new one. This action may alsoestablish first connection when the application isstarted before the input method.Text Selections for Application ProgrammersThe default behavior of the text selection array is described in the section calledText Selections for Users. To modify the selections a programmer must constructa XawTextSelectType array (called the selection array), containing the selectionsdesired, and pass this as the new value for the selectionTypes resource.The selection array may also be modified using the XawTextSetSelectionArrayfunction. All selection arrays must end with the value XawselectNull. The selectionTypesresource has no converter registered and cannot be modified throughthe resource manager.The array contains a list of entries that will be called when the user attempts to selecttext in rapid succession with the select-start action (usually by clicking a pointerbutton). The first entry in the selection array will be used when the select-startaction is initially called. The next entry will be used when select-start is called again,and so on. If a timeout value (1/10 of a second) is exceeded, the the next select-startaction will begin at the top of the selection array. When XawselectNull is reachedthe array is recycled beginning with the first element.XawselectAllXawselectCharXawselectLineXawselectNullXawselectParagraphXawselectPositionXawselectWordSelects the contents of the entire buffer.Selects text characters asthe pointer moves over them.Selects the entire line.Indicates the end of the selection array.Selects the entire paragraph.Selects the current pointer position.Selects whole words as thepointer moves onto them.The default selectType array is:{XawselectPosition, XawselectWord, XawselectLine, XawselectParagraph, XawselectAll,The selection array is not copied by the text widgets. The application must allocatespace for the array and cannot deallocate or change it until the text widget is destroyedor until a new selection array is set.74
