320) Why is XtWindow(widget) == 0?

[Last modified: Oct 95]

Answer:  The window is not created until the widget is realized.  In general,
using XtWindow() is a bad idea.  In most cases, you can create more robust
code by subclassing the widget and putting your window code in new wiget class
methods.
