How to know if this window is on the top.
Posted: 24 Nov 2023 2:48
I spent several days try find out solution but fail. so I put it here ask for help.
I have made a normal MDI application, which can open multiple instances (Form Windows) for editing pictures, etc. I have "Redo", "Undo" menu in the TaskWindow menubar. But how can I know which window is at the top, that those function can work only on this window? I tried use listener "Activate listener", "GetFocus listeners", "StateChange Listeners" but all no helpful.
Thank you
