# Tk::FireButton(3pm)

Button that keeps invoking callback when pressed

## NAME

Tk::FireButton - Button that keeps invoking callback when pressed

## SYNOPSIS

```
    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, ...);
```

## DESCRIPTION

**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.

## SUPER-CLASS

The **FireButton** widget-class is derived from the **Button** widget-class and inherits all the methods and options its super-class (see Tk::Button).

## STANDARD OPTIONS

**FireButton** supports all the standard options of a **Button** widget. See Tk::options for details on the standard options.

## WIDGET-SPECIFIC OPTIONS

- Name: **repeatDelay**

  - Class: **RepeatDelay**

  - Switch: **-repeatdelay**

  - Fallback: **300** (milliseconds)

  Specifies the amount of time before the callback is first invoked after the Button-1 is pressed over the widget.

- Name: **repeatInterval**

  - Class: **RepeatInterval**

  - Switch: **-repeatinterval**

  - Fallback: **100** (milliseconds)

  Specifies the amount of time between invocations of the callback bound to the widget with the `"command"` option.

## CHANDED OPTION FALLBACK VALUES

The fallback values of the following options as different from the **Button** widget:

```
        -padx               => 0,
        -pady               => 0,
```

## METHODS

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.

## ADVERTISED WIDGETS

None.
