Overloading onSize

Hi

I wanna overload onsize, but not realy sure how to do it. Problem: My application is resizeable... but the application should not be smaler then 400 * 400.

OnSize(..)
{
//When new size is smaler then 500 * 500 pixels.. don't resize
}

But, how is that done ?

Hi win32,

to avoid flickering it's better to restrict window-sizes by handling the WM_GETMINMAXINFO
message. Override CWnd::OnGetMinMaxInfo() for your window's class and in there simply
set the ptMinTrackSize member of the passed MINMAXINFO to 500, 500.

hope that helps,

I have doen like this:

void CChildView::OnGetMinMaxInfo( MINMAXINFO FAR* lpMMI )
{
POINT pMin;
pMin.x = 100;
pMin.y = 100;
lpMMI->ptMinTrackSize = pMin;
CWnd::OnGetMinMaxInfo(lpMMI);
}

But it does not work ???

Thought you wanted it to be 400 * 400 or 500 * 500???

Also, looks like you want to make sure a child frame in an MDI app is what you want to restrict, correct??

Zoppo

And, maybe you should modify the values after you called CWnd::OnGetMinMaxInfo()
coz maybe there the values are modified again...

Hmm I made a mistake, I was modifying a child wnd to the main wnd.. now it works :-)

I'm not happy about this because you simply accepted captainkirk's comment as answer
without telling a reason what's wrong with my comment.
