Tweeeeeeeet! Five code line penalty for misleading information! :-)
This is a different problem than the one you originally described.
You need to clear the drawing area -- it is *not* automagically
cleared for you. Here's what I do in a Free Object handler I use:
int freeobj_hduml_free_handle( FL_OBJECT *ob, int event,
FL_Coord mx, FL_Coord my,
int key, void *xev )
{
FL_EVENTS event_enum = ( FL_EVENTS ) event;
switch ( event_enum ) {
case FL_NOEVENT: {
break;
}
case FL_DRAW: {
/*
* Clear the drawing area.
*/
fl_drw_box( ob->boxtype,
ob->x, ob->y, ob->w, ob->h,
ob->col1, abs( ob->bw ) );
/* Do other drawing here */
break;
}
[...]
Two things of note:
First, I do not redraw the Free Object on the arrival any other event
than an FL_DRAW -- the manual specifically discusses this, I believe.
Second, note the fl_drw_box() function call. It clears the drawing
area in the Free Object to the appropriate background color and draws
the border.
