Closing parent window causes Error

Submitted by Anonymous on Wed, 08/13/2003 - 21:16.

I have created a child window with the following
code
hp->hpw.top = XtVaCreatePopupShell ("radio_hardware_parameters_setup",
topLevelShellWidgetClass,
parent,
wargs,
n);

parent is the parent shell. When I close
the parent I get an error message
Error XtPopdown requires a subclass
of shellWidgetClass.
This error seems to be random, so what
do I need to do create this child window
correctly?

"Close" the window, how?

The code looks OK.

Unusual Xt messages are often indicators that the
underlying data structures have been corrupted. You can use a tool
that looks for out-of-bounds memory-writes (such as Purify).
