Par2: Changing MDI/SDI behavior at runtime 2008-05-21 -- Lee White > Can I change the way a window performs at execution time. I have an MDI

The MDI attribute of a window is defined when the window is created at
the OS level. To the best of my knowledge that cannot be changed once
the window has been created.
There is a way around this in Clarion but it involves some work to
accomplish. If your window is in a hand coded procedure it's a lot
easier to do. You can create a copy of the window without the MDI
attribute and use a reference within you code, such as...
Window1 WINDOW('Whatever'),AT(,,400,202),MDI
END
Window2 WINDOW('Whatever'),AT(,,400,202)
END
Window &WINDOW
CODE
IF MakeItMDI
Window &= Window1
ELSE
Window &= Window2
END
OPEN(Window)
The real work begins if you want to avoid the warnings about duplicate
controls. You have to use the 3rd parameter of USE() to prevent
duplication.
