GOAL:
How to manage which windows are enabled/disabled in a multi-window application ?
GOAL:
How to prevent input in one window while other windows are opened ?
FIX:
There are many ways to achieve this, and which one works best depends on how the application is architectured.
Two relatively easy approaches to handle this are:
1. Giving each window one or more internal procedures that manage which
widgets should be active and/or inactive. These procedures can then be
used from anywhere in your application to change the state of the window
as required.
2. Replacing windows with dialog boxes. As long as a Dialog box is open,
it is the only window that can have focus, effectively blocking all
other windows active at the time.
