没有标题栏的窗体怎么移动啊~

嘴角上扬

网上找了很多代码都木有用啊~那个改消息的代码其他按键响应都没用了，有木有人知道的哇~

procedure TFRM_Date.Label1MouseMove(Sender: TObject; Shift: TShiftState; X,
  Y: Integer);
begin
  ReleaseCapture;
  Perform(WM_SYSCOMMAND, $F012, 0); //此行为无标题移动框体
end;
XP/win7下通过

就是在窗口的MouseMove事件中加入

鼠标拖动控件时用的panel1.Perform(WM_SYSCOMMAND, $F012, 0);这个$F012这个命令在定义里没有，其实它是SC_MOVE or 2的结果，微软的文档中提到WM_SYSCOMMAND命令中wParam的值的低4位值是保留的。

举例说明：
在Form的MouseDown事件里写如下代码
ReleaseCapture;
Perform(WM_SYSCOMMAND, SC_SIZE OR 1, 0); // Left
Perform(WM_SYSCOMMAND, SC_SIZE OR 2, 0); // Right
Perform(WM_SYSCOMMAND, SC_SIZE OR 3, 0); // Top
Perform(WM_SYSCOMMAND, SC_SIZE OR 4, 0); // left-top
Perform(WM_SYSCOMMAND, SC_SIZE OR 5, 0); // Right-top
Perform(WM_SYSCOMMAND, SC_SIZE OR 6, 0); // bottom
Perform(WM_SYSCOMMAND, SC_SIZE OR 7, 0); // left-bottom
Perform(WM_SYSCOMMAND, SC_SIZE OR 8, 0); // right-bottom
