如何使WS_THICKFRAME不可见,但仍在MFC中运行？

Question

所以,我创建了一个具有样式的对话框:WS_THICKFRAME.这个WS_THICKFRAME为对话框提供了调整窗口大小的功能,但我的问题是我不会在窗口周围看到边框.如何使边框不可见,但仍具有重新尺寸功能？

一个例子是最有帮助的!谢谢!

下面是我创建的对话框的模板样式:

IDD_GADGETTRANSLUCENTDIALOG DIALOGEX 0, 0, 320, 200
STYLE DS_ABSALIGN | DS_SETFONT | DS_MODALFRAME | DS_3DLOOK | DS_FIXEDSYS | WS_SYSMENU | WS_THICKFRAME

Answer 1

删除WS_THICKFRAME

处理WM_NCHITTEST大致如下:

UINT CMyClass::OnNcHitTest(CPoint point) 
{
   CRect rWindow;
   GetWindowRect(rWindow);

   CRect rInner(rWindow);
   rInner.DeflateRect(GetSystemMetrics(SM_CXBORDER), GetSystemMetrics(SM_CYBORDER));

   if (rWindow.PtInRect(point) && !rInner.PtInRect(point))
   {
      // figure out which of the following codes to return: //
      // HTBOTTOM, HTTOP, HTLEFT, HTRIGHT                   //
      // HTBOTTOMLEFT, HTBOTTOMRIGHT, HTTOPLEFT, HTTOPRIGHT // 
   }
   else
   {
      return CMyBaseClass::OnNcHitTest(point);
   }
}
