Here is a simple question on SUN4/260, color monitor. However, it makes
me like a crazy man.
I create a composite widget on the toplevel(shell widget). After that, I
put a text widget and a viewport widget on that composite widget just created.
Although the XtNbackground property is set before I create the specific widget,
the backgrounds of the result widgets are still the same as the one of their
parent widget. Did I miss something important? Or, I misuse the
XtCreateManagedWidget? I have tried to change the attribute of background by
using XSetWindowAttributes after the widgets are realized. But the result is
the same as before. Any advice is appreciated. Thanks in advance.
By the way, how can I create a widget with a specific visual class?

There was a bug in the AsciiText widgets corrected by fix #28 which
should have solved this problem for Text. The Viewport widget is
supposed to be completely obscured by its children, so it ignores it's
background resource. This bug will be fixed in the next release.
