The following are called just before the show_form call in the main
program.
fl_addto_selected_xevent(FL_ObjWin(gpGlunk->button1, ExposureMask);
fl_register_raw_callback(gpGlunk->form, Expose,
(FL_RAW_CALLBACK)do_expose);
This is my callback function. Should it have been defined as returning
type FL_RAW_CALLBACK? I had to cast it to get rid of the warning from the
fl_register_raw_callback call.
int do_expose(XEvent *ppXEvent, void **ppParm2)
{
char Str0[150];
sprintf(Str0, "Event type: %d, expose type: %d",
ppXEvent->type, ppXEvent->xexpose.type);
fl_show_messages(Str0);
return 0;
}
The problem I am having is twofold.
First, no matter what I do or click on, both event and expose type always
come up as 50304.
Second, no matter what I do, the function do_expose is the only callback
called. All button, slider, etc callbacks are seemingly masked, even
though the function returns 0 instead of FL_PREEMPT.
Can anybody tell me what I'm misunderstanding or doing wrong?
Just for reference, the definitions out of Xlib.h are:
typedef union _XEvent {
int type;
XExposeEvent xexpose;
...
} XEvent;
typedef struct {
int type;
...
} XExposeEvent;
