How to make a form non-moveable

Answer:

It is easy to make a form non-moveable.
Choose a borderstyle like bsDialog so that the window can not be resized.

Then add an handler for the WM_WINDOWPOSCHANGING message and override the change.


1   type
2     TMyForm = class(TForm)
3     protected
4       procedure OnPosChange(var Msg: TWmWindowPosChanging); message
5         WM_WINDOWPOSCHANGING;
6     end;
7   
8   procedure TForm1.OnPosChange(var Msg: TWmWindowPosChanging);
9   begin
10    Msg.WindowPos.x := Left;
11    Msg.WindowPos.y := Top;
12    Msg.Result := 0;
13  end;
