还有一个：用鼠标移动怎样移动无标题栏的窗口啊？

Question

基于对话框的无标题栏的窗口……

Answer 1

void CDemoDlg::OnLButtonDown(UINT nFlags, CPoint point) 
{
    SendMessage(WM_SYSCOMMAND,0xF012,0);
    CDialog::OnLButtonDown(nFlags, point);
} 一句话……

Answer 2

void CXXXDlg::OnLButtonDown(UINT nFlags, CPoint point) 
{
SendMessage(WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM(point.x, point.y));
PostMessage(WM_LBUTTONUP, NULL, MAKELPARAM(point.x, point.y)); CDialog::OnLButtonDown(nFlags, point);
}

Answer 3

不加WM_LBUTTONUP，会扰乱正常的鼠标down、up时间顺序。

Answer 4

CDialog::OnLButtonDown(nFlags, point)里加上:PostMessage(WM_NCLBUTTONDOWN,HTCAPTION,MAKELPARAM(point.x, point.y));
