Hi, you can create your own TPanel descendant to do this easily:
type
TDragMovePanel = class(TPanel)
protected
procedure MouseDown(Button: TMouseButton; Shift: TShiftState; X,
Y: Integer); override;
end;
procedure TDragMovePanel.MouseDown(Button: TMouseButton; Shift:
TShiftState; X, Y: Integer);
begin
if (Button = mbLeft) then begin
ReleaseCapture;
Perform(WM_SYSCOMMAND, SC_DRAGMOVE, 0);
end else begin
inherited MouseDown(Button, Shift, X, Y);
end;
end;
Maybe this also works inside a TPanel's OnMouseDown event, but I
haven't tested that.
HTH,
Markus
