Window transition event

[Natter]

Hi,

Is it possible to intercept the window transition event to the background/foreground ?

Dear Yuri,

Use the WM_ACTIVATE message in the application's main window procedure. This message indicates window activation changes (activating/deactivating).
Combine with the LOWORD of wParam to check the activation state (e.g., WA_INACTIVE for background).

You may need to inherit a Class TMyWindow from TWindow and implement support for WM_ACTIVATE

There are some examples in these forums showing how to inherit and modify Method HandleEvent()

Thank you, Antonio! I'll try.
