Repeater Widget Application header file <X11/Xaw/Repeater.h> Class header file <X11/Xaw/RepeaterP.h> Class repeaterWidgetClass Class Name Repeater Superclass Command The Repeater widget is a subclass of the Command widget; see the Command documentation for details. The difference is that the Repeater can call its registered callbacks repeatedly, at an increasing rate. The default translation does so for the duration the user holds down pointer button 1 while the pointer is on the Repeater. Resources When creating a Repeater widget instance, the following resources are retrieved from the argument list or from the resource database: Name Class Type Notes Default Value accelerators Accelerators AcceleratorTable NULL ancestorSensitive AncestorSensitive Boolean D True background Background Pixel XtDefaultBackground backgroundPixmap Pixmap Pixmap XtUnspecifiedPixmap bitmap Bitmap Pixmap None borderColor BorderColor Pixel XtDefaultForeground borderPixmap Pixmap Pixmap XtUnspecifiedPixmap borderWidth BorderWidth Dimension 1 callback Callback XtCallbackList NULL colormap Colormap Colormap Parent's Colormap cornerRoundPercent CornerRoundPercent Dimension 25 cursor Cursor Cursor None cursorName Cursor String NULL decay Decay Int 5 depth Depth int C Parent's Depth destroyCallback Callback XtCallbackList NULL encoding Encoding UnsignedChar XawTextEncoding8bit flash Boolean Boolean False font Font XFontStruct XtDefaultFont fontSet FontSet XFontSet XtDefaultFontSet foreground Foreground Pixel XtDefaultForeground height Height Dimension A graphic height + 2 * internalHeight highlightThickness Thickness Dimension A 2 (0 if Shaped) initialDelay Delay Int 200 insensitiveBorder Insensitive Pixmap GreyPixmap internalHeight Height Dimension 2 internalWidth Width Dimension 4 international International Boolean C False justify Justify Justify XtJustifyCenter (center) label Label String name of widget leftBitmap LeftBitmap Bitmap None mappedWhenManaged MappedWhenManaged Boolean True minimumDelay MinimumDelay Int 10 pointerColor Foreground Pixel XtDefaultForeground pointerColorBackground Background Pixel XtDefaultBackground repeatDelay Delay Int 50 resize Resize Boolean True screen Screen Pointer R Parent's Screen sensitive Sensitive Boolean True shapeStyle ShapeStyle ShapeStyle Rectangle startCallback StartCallback Callback NULL stopCallback StopCallback Callback NULL translations Translations TranslationTable See below width Width Dimension A graphic width + 2 * internalWidth x Position Position 0 y Position Position 0 \" Resource Descriptions decay The number of milliseconds that should be subtracted from each succeeding interval while the Repeater button is being held down until the interval has reached minimumDelay milliseconds. flash Whether or not to flash the Repeater button whenever the timer goes off. initialDelay The number of milliseconds between the beginning of the Repeater button being held down and the first invocation of the callback function. minimumDelay The minimum time between callbacks in milliseconds. repeatDelay The number of milliseconds between each callback after the first (minus an increasing number of decays). startCallback The list of functions to invoke by the start action (typically when the Repeater button is first pressed). The callback data parameter is set to NULL. stopCallback The list of functions to invoke by the stop action (typically when the Repeater button is released). The callback data parameter is set to NULL. Repeater Actions The Repeater widget supports the following actions beyond those of the Command button: start() This invokes the functions on the startCallback and callback lists and sets a timer to go off in initialDelay milliseconds. The timer will cause the callback functions to be invoked with increasing frequency until the stop action occurs. stop() This invokes the functions on the stopCallback list and prevents any further timers from occuring until the next start action. The following are the default translation bindings used by the Repeater widget: <EnterWindow>: highlight(\|) <LeaveWindow>: unhighlight(\|) <Btn1Down>: set(\|) start(\|) <Btn1Up>: stop(\|) unset(\|)
