Member Function Documentation

int Fl_Clock::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
