I am trying to create a file_selection widget. I am making it
the child of an attached dialog box which is the child of the main
window. Then I define the file_selection widget, taking all the
defaults. Then later on a list_box widget is trying to attach
to the file_selection widget. I am defining this in a uil file
and managing the whole thing once in the 'c' file. When I run the
executable, I get an error :
'X Toolkit Warning: Not all Children have same parent in
XtManageChildren.'
In addition, the file_selection widget and the attached list_box
widget do not appear on my screen.
However, if I go through my code and redefine the file_selection
widget to be a label widget, it works fine. There is no warning
and the label appears on the screen, with the attached list_box
widget.
does anyone have any clues about what the problem is? I suspected
that it had to do with the file_selection dir_mask, but I tried
defining that with no results. I have also tried setting the style
to DwtWorkarea, but that didn't work either.

They do have different parents. The toolkit inserts a HiddenShell widget between the widget you declare as the file selection widget's parent and the file selection widget. Just manage the two with separate calls to XtManageChild. Leo | |||||

Thank you, that worked! Two questions:
1. Did you just know that information or did you look it up in the
documentation? (I looked and found nothing.)
2. So what is the name of the file selection box's parent? My
file selection widget's parent is an attached dialog box. It's parent
is the main window widget. So, is the file selection widget's ultimate
parent the same as the main window's? I apologize if I am unclear.

Just knew it... (I'm responsible for that "feature"...)

The HiddenShell widget's name is "Popup". When you create a
fileselection widget as the child of an attached dialog box, what
you really get is a HiddenShell widget which is a "popup" child
of the attached dialog box, and the fileselecton widget, which is
the "normal" child of the HiddenShell. You could look in the
DECwindows Guide to Application Programming (I think it's called)
or an Intrinsics book for information on the difference between
"popup" and "normal" widget children.
