Emulation of the Forms "free" widget.
|
|
|
|
This emulation allows the free demo to run, and appears to be useful for
|
|
porting programs written in Forms which use the free widget or make
|
|
subclasses of the Forms widgets.
|
|
|
|
There are five types of free, which determine when the handle function
|
|
is called:
|
|
|
|
\li \c FL_NORMAL_FREE normal event handling.
|
|
\li \c FL_SLEEPING_FREE deactivates event handling (widget is inactive).
|
|
\li \c FL_INPUT_FREE accepts FL_FOCUS events.
|
|
\li \c FL_CONTINUOUS_FREE sets a timeout callback 100 times a second and
|
|
provides an FL_STEP event. This has obvious
|
|
detrimental effects on machine performance.
|
|
\li \c FL_ALL_FREE same as FL_INPUT_FREE and FL_CONTINUOUS_FREE.
