1604.0. "Is VisibilityUnobscured possible?" by LITE::B_WACKER () Thu Oct 19 1989 14:01

Using the program in 1414.2 it seems impossible to get a 
VisibilityUnobscured event.  Completely exposing the windows always 
gives:

visibility event window = parent VisibilityPartiallyObscured
visibility event window = w1 VisibilityPartiallyObscured

A customer says it works on an RT and wants to know why it doesn't on ours.

1604.1Window manager interaction?DECWIN::KLEINFri Oct 20 1989 10:559
I suspect that the visibility criteria includes the window borders.  If you're
running a window manager, the window manager supplies a window frame around
each application window.  That window frame obscures the application window's
borders, therefore the application window is never really completely visible.

Have you tried running without a window manager?

1604.2What's the WM supposed to do?LITE::B_WACKERFri Oct 20 1989 11:2510
>Have you tried running without a window manager?

No, I haven't because that wasn't the customer's situation.  

I thought the border was added around the outside of the window,
though. Also, in the sample code there's a window within the main
window which also never gets unobscured.
