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

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. Printed May 12, 2024, 6:29 am This article has been viewed/printed 35122 times. |
