Delphi Form State and State Size

This is not visible within the VCL. Instead, you need to dive into the Win32 API. You need a function GetWindowPlacement

.

var
  WindowPlacement: TWindowPlacement;
....
WindowPlacement.length := SizeOf(WindowPlacement);
Win32Check(GetWindowPlacement(Form.Handle, WindowPlacement));

      

        
        
        
      

    

The required information can be found in the structure WindowPlacement

. Beware that coordinates are reported relative to the stage, not the screen.

You usually need this information so you can recover it later. Use SetWindowPlacement

for this.
