It's me again...
I'm still working on implementing a widget of my own design under athena.
My Widget has a bunch of stuff that needs to be released/freed before it dies,
including the removal of a tmp file.
In my widget's .c file is as follows:
.
.
.
static void Destroy();
.
.
.
MyWidgetClassRec myWidgetClassRec = {
.
.
.
/* visible_interest */ FALSE,
/* destroy */ Destroy,
.
.
.
}
static void Destroy(w, call, client)
{
printf(I'm in Destroy...\n);
fflush(stdout);
/*
* free my widget stuff
* remove temp file
*/
}
My Application Exit function looks like this:
void Exit(status)
int status;
{
XtUnmapWidget(top);
XtDestroyApplicationContext(XtWidgetToApplicationContext(top));
exit(status);
}
However,
My widget's destroy function is never getting called. Am I missing something
here? I've tried explicitly calling XtDestroyWidget(myWidget), before
the XtDestroyAppl call in Exit, and I've also tried not defining the
Destroy callback in the WidgetRec, but using XtAddCallback in the
Initializes routine of my widget. None of these work? What am I doing
wrong?
Considering all the discussion about memeory leaks, this seems pretty
important.
