Mouseposition innerhalb des Forms bestimmen

[bitsetter]

Wenn du das Handle des fremden Fensters kennst, müsste folgendes funktionieren.

Delphi-Quellcode:

function GetPos(Handle: HWND): TPoint;
var
   WinInfo: TWindowInfo;
   CurPos: TPoint;
begin
   Result.X:= -1;
   Result.Y:= -1;
   FillChar(WinInfo, Sizeof(WinInfo), 0);
   WinInfo.cbSize := Sizeof(WinInfo);
   GetWindowInfo(Handle, WinInfo);
   GetCursorPos(CurPos);
   //if windows.PtInRect(WinInfo.rcWindow, CurPos) then
   if windows.PtInRect(WinInfo.rcClient, CurPos) then
     begin
       Result.X:= CurPos.X- WinInfo.rcClient.Left;
       Result.Y:= CurPos.Y- WinInfo.rcClient.Top;
     end;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  CurPos: TPoint;
begin
  CurPos:= GetPos(Form1.Handle);
  Caption:= 'X: '+inttostr(CurPos.X)+ '  Y: '+inttostr(CurPos.Y);
end;

procedure SetPos(Handle: HWND; CurPos: TPoint);
var
   WinInfo: TWindowInfo;
begin
   FillChar(WinInfo, Sizeof(WinInfo), 0);
   WinInfo.cbSize := Sizeof(WinInfo);
   GetWindowInfo(Handle, WinInfo);
   inc(CurPos.X, WinInfo.rcClient.Left);//WinInfo.rcWindow.Left
   inc(CurPos.Y, WinInfo.rcClient.Top);//WinInfo.rcWindow.Top
   if windows.PtInRect(WinInfo.rcClient, CurPos) then
   setCursorPos(CurPos.X, CurPos.Y);
end;

procedure TForm1.Button2Click(Sender: TObject);
var
  CurPos: TPoint;
begin
  CurPos.X:= 5;
  CurPos.Y:= 15;
  SetPos(Form1.Handle, CurPos);
end;

Ich hoffe mal, du meintest es auch so.
