Form ohne Rahmen bewegen

[DeddyH]

Ganz unspektakuläre Möglichkeit:

Delphi-Quellcode:

type
  TForm1 = class(TForm)
    Image1: TImage;
    procedure Image1MouseDown(Sender: TObject; Button: TMouseButton;
      Shift: TShiftState; X, Y: Integer);
    procedure Image1MouseMove(Sender: TObject; Shift: TShiftState; X,
      Y: Integer);
  private
    { Private-Deklarationen }
    FInitialPos: TPoint;
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Image1MouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
begin
  FInitialPos := Point(X, Y);
end;

procedure TForm1.Image1MouseMove(Sender: TObject; Shift: TShiftState; X,
  Y: Integer);
begin
  if ssLeft in Shift then
    begin
      Left := Left + X - FInitialPos.X;
      Top := Top + Y - FInitialPos.Y;
    end;
end;
