Volume 6A: Motif Programming Manual

TemplateDialog, which is basically an empty MessageDialog that can be modified by the programmer. By default, the

dialog only contains a Separator child. By setting various resources on a TemplateDialog when it is created, you can

button is created. If you set the XmNmessageString resource, the message is displayed in the standard location. If

particular resource, then that child is not created, which means that you cannot modify the resource later with

XtSetValues(), set a callback for the child with XtAddCallback(), or retrieve the child with

XmMessageBoxGetChild().

that is added is taken as the work area, regardless of whether it is a PushButton or a MenuBar. The fact that the first

child is always considered the work area is a bug. As a result of the bug, you need to be careful about the order in
