I have an application that uses a pop-up message box. It was working fine until I decided to make it modeless (it was obscuring part of the error it was reporting). When I changed style = DwtModeless, the application went into an infinite loop inside XtManageChild on that widget. Any ideas on how I can find out what's happening? Thanks, Barry

How do you know that it is looping? Could you post an example? Bill | |||||
| 2832.2 | Here is the UIL description of the message box and the code it gets stuck in. | AIAG::LATHAM | Flags do not wave in a vacuum | Tue Jun 05 1990 16:36 | 45 |
I know its looping because I run it with the debugger on and step through it
and look at the pc and the pc loops somewhere inside XtManageChild.
object
MBOX : message_box {
arguments {
default_position = true;
resize = DwtResizeShrinkWrap;
! style = DwtModeless; Commented out to work
title = "DECtree Messages";
};
callbacks {
create = procedure create_proc (k_mbox);
};
};
MakeMessageBox1(str)
char *str;
{
char *s;
DwtCompString cs;
for (s=str;*s;s++) {
if (*s==9) *s=' ';
}
if (toplevel==NULL) { fprintf(stderr,str); return; }; /* no DECwindows */
cs = DwtLatin1String(str);
if (widget_array[k_mbox] == NULL)
/* First time fetch */
if (DwtFetchWidget(dt_DRMHierarchy,"MBOX",
toplevel,
&widget_array[k_mbox],
&class) != DRMSuccess)
dt_error("Can't fetch MBOX");
set_something(widget_array[k_mbox],DwtNlabel,cs);
XtFree(cs);
XtManageChild(widget_array[k_mbox]);
}

| 2832.3 | It works now, I'm not sure why | AIAG::LATHAM | Flags do not wave in a vacuum | Thu Jun 21 1990 15:00 | 1 |
could have been fixed when I fixed a malloc problem I had elsewhere. | |||||
