CDlg 窗口的分割 收缩和扩张

                      CDlg 窗口的分割 收缩和扩张

 

1 增加一个分割符

          采用图像控件

2 确定收缩后对话框的Rect的那些要素要发生变化

3 保存原来的对话框的大小 为了恢复

4 确定收缩后的对话框的大小

一下是源代码

 

void CDialogDlg::OnButton2()

{

       // TODO: Add your control notification handler code here

       CString str;

       if(GetDlgItemText(IDC_BUTTON2, str),str == "收缩<<")

       {

              SetDlgItemText(IDC_BUTTON2, "扩展>>");

       }else

       {

              SetDlgItemText(IDC_BUTTON2, "收缩<<");

       }

       static CRect rectLarge;

       static CRect rectSmall;

      

       if(rectLarge.IsRectNull())

       {

              CRect rectSeparator;

              GetWindowRect(rectLarge);

              GetDlgItem(IDC_SEPARATOR)->GetWindowRect(rectSeparator);

              rectSmall.left = rectLarge.left;

              rectSmall.bottom = rectSeparator.bottom;

              rectSmall.top = rectLarge.top;

              rectSmall.right = rectLarge.right;

       }

       if(str == "收缩<<")

       {

             

              SetWindowPos(NULL,0,0,rectSmall.Width(),rectSmall.Height(),SWP_NOMOVE | SWP_NOZORDER);

       }

       else

       {

              SetWindowPos(NULL,0,0,rectLarge.Width(),rectLarge.Height(),SWP_NOMOVE | SWP_NOZORDER);

       }

}
