Minimizing and restoring a maximized window

[Attila Kovacs 629]

I have a form, designed size let's say 640x680. Everything dynamic, every control is inside a TGridPanel, aligned.

Designed formstate wsMaximized, one button can minimize the app with Application.Minimize or ShowWindow(Handle, SW_MINIMIZE).

Everything fine. For the fist sight. But:

On startup, the form will be rendered in 640x680 then resized to fullscreen and re-rendered.

On minimize, form will silently resized to 640x680, rendered while it's became invisible, and on restore resized again to fullscreen and re-rendered again.

How should I skip the unnecessary resizings/renderings/align calculations?

Hm, looks like the solution is easier than I thought.

Instead of setting the formstate to wsMaximized, if I'm setting the form's width and height to the Screen's width and height in the OnCreate event,

the problems are gone.
