## Detailed Description

The Fl_Repeat_Button is a subclass of Fl_Button that generates a callback when it is pressed and then repeatedly generates callbacks as long as it is held down.

The speed of the repeat is fixed and depends on the implementation.

## Constructor & Destructor Documentation

Fl_Repeat_Button::Fl_Repeat_Button | ( | int | X,
|  | int | Y,
|  | int | W,
|  | int | H,
|  | const char * | l = `0`
| ) |  |

Creates a new Fl_Repeat_Button widget using the given position, size, and label string.

The default boxtype is FL_UP_BOX. Deletes the button.

## Member Function Documentation

int Fl_Repeat_Button::handle | ( | int | event | ) |
| virtual

Handles the specified event.

You normally don't call this method directly, but instead let FLTK do it when the user interacts with the widget.

When implemented in a widget, this function must return 0 if the widget does not use the event or 1 otherwise.

Most of the time, you want to call the inherited handle() method in your overridden method so that you don't short-circuit events that you don't handle. In this last case you should return the callee retval.

Parameters

  [in] | event | the kind of event received

Return values

  0 | if the event was not used or understood
  1 | if the event was used and can be deleted
