I've created an application that brings up a dialog box upon selection
of one of the popup menu buttons. The dialog box consists of three staticText
widgets, two textEdit widgets, and two buttons. When one of the buttons is
selected, a callback routine is invoked. This callback tries to modify the
text displayed in one of the staticText widgets. All of the widgets described
above are declared as global veriables.
The problem I'm having is that when I call XtSetValues() to change
the string displayed in the staticText widget, the widget dies. Is there
any reason why I shouldn't be able to change the attributes of a widget which
is the child of a transientShell (my popup shell) from a menu button
callback?
Here's some of the code:
/**********************************/
/**** Callback Functions **********/
/**********************************/
void start_testing (w, client_data, call_data)
Widget w;
caddr_t client_data, call_data;
{
int k, try = 0;
char string[80];
enum boolean unit_found;
Arg sargs[15];
printf ("start testing\n");
if ( valid_wo_flag == true ) {
set_selects (rdpy, &unit_found);
if (unit_found == false)
printf ("unit_found is false\n");
else if (unit_found == true)
printf ("unit_found is true\n");
else
printf ("unit_found is unknown: %d\n", unit_found);
while ( unit_found == false) {
/** pop up error box **/
printf ("try: %d\n", try);
set_selects (rdpy, &unit_found);
sleep (10);
try++;
k = 0;
XtSetArg (sargs[k], XtNstring, "Hell"); k++;
XtSetValues (gwoSt2, (ArgList)sargs, k);
XFlush (ldpy);
} /* while */
XtCallCallbacks (gwoNO, XtNrelease, NULL);
} /* if */
}
