# To subscribers of the xforms list from myaconis@nlxcorp.com :
I appreciate this question because I am currently modifying an application that will suffer from the same problem. The following seems to work effectively.
When creating the transient form I registered a raw callback
fl_register_raw_callback( form,
FL_ALL_EVENT,
raw_routine_cb );
The routine is
int raw_routine_cb( FL_FORM *form, void *xev )
{
int type = ((XEvent *)xev)->type;
printf("Got an %d event!\n", type);
if (type == ClientMessage)
{
printf("Got an %d event! ClientMessage\n", type);
//do whatever you need to do to close the
//the transient window
return FL_PREEMPT;
}
return 0;
}

On my Redhat Linux 7.2 machine (using KDE) I noticed minimizing the form generated the UnmapNotify event but closing the form from the exit button on the border generated a ClientMessage event. By capturing this event and preempting further handling of it, the "main" application remains open.
Perhaps the FL_ALL_EVENT is overkill but I wasn't sure if just the ButtonPress and ButtonRelease Masks would do the trick... perhaps I'll fool around with that some.
(Sorry about the HTML encoded email...my Lotus Notes Mail web client can be a pain!)

By "signal" I assume you mean XEvent. They're different critters.
The server generates an UnmapNotify event when a window changes state
from mapped to unmapped.
