如何限制用户调整窗口大小 [英] How to restrict window resizing by user

问题描述

如何阻止用户将窗口调整为最大大小?我确实希望允许用户将窗口的大小调整到某个特定限制.如果用户尝试将窗口的大小调整为超出该限制，则程序不得允许他这样做.

How can i stop user from resizing window upto certain limit? I do want to allow user for resizing a window upto some certain limit. If User try to resize window beyond that limit, program must not allow him to do so.

推荐答案

重写CWnd :: OnGetMinMaxInfo.请参见此处 [

Override CWnd::OnGetMinMaxInfo. See here[^] for a whole discussion about it.

完成！非常感谢.

但是我有更改限制.

Done !! Thanks a lot.

But i have change limit.

lpMMI->ptMinTrackSize.x = 1000; 
lpMMI->ptMinTrackSize.y = 700;

代替

in place of

lpMMI->ptMaxTrackSize.x = 1000; 
lpMMI->ptMaxTrackSize.y = 700;

我做了此更改是因为我确实想阻止用户将大小从最大调整为最小.不是从最小到最大.

I have done this change because i do want to stop user from resizing from maximum to minimum. not from minimum to maximum.

对不起:)

Sorry :)

BEGIN_MESSAGE_MAP(CYourWnd, CBaseOfYouWnd)
  //{{AFX_MSG_MAP(CYourWnd)
...
  ON_WM_GETMINMAXINFO()
  //}}AFX_MSG_MAP
END_MESSAGE_MAP()
    
void CYourWnd::OnGetMinMaxInfo(MINMAXINFO* lpMMI)
{
  lpMMI->ptMaxTrackSize.x = 400;
  lpMMI->ptMaxTrackSize.y = 200;
}
