Tk::FireButton - Button that keeps invoking callback when pressed
use Tk::FireButton; $fire = $parent->FireButton( ... ); # May/should change: $w->Whatever(... -bitmap => $Tk::FireButton::INCBITMAP, ...); $w->Whatever(... -bitmap => $Tk::FireButton::DECBITMAP, ...); $w->Whatever(... -bitmap => $Tk::FireButton::HORIZINCBITMAP, ...); $w->Whatever(... -bitmap => $Tk::FireButton::HORIZDECBITMAP, ...);
FireButton is-a Button widget (see Tk::Button) that keeps invoking the callback bound to it as long as the <FireButton> is pressed.
Four suitable bitmaps are predefined in this package: $INCBITMAP and $DECBITMAP for vertical increment and decrement buttons, and $HORIZINCBITMAP and $HORIZDECBITMAP for horizontal increment and decrement buttons. See below for methods accessing these bitmaps.
The FireButton widget-class is derived from the Button widget-class and inherits all the methods and options its super-class (see Tk::Button).
FireButton supports all the standard options of a Button widget. See Tk::options for details on the standard options.
Specifies the amount of time before the callback is first invoked after the Button-1 is pressed over the widget.
Specifies the amount of time between invokations of the callback bound to the widget with the
The fallback values of the following options as different from the Button widget:
-padx => 0, -pady => 0,
Same as for Button widget.
Additionally, there are four methods returning the names of the standard increment and decrement bitmaps: INCBITMAP, HORIZINCBITMAP, DECBITMAP, and HORIZDECBITMAP.
Subclasses of FireButton may override these methods to supply different increment and decrement bitmaps.
