I’am writing some terminal program of sorts. The thing is i want window to be resisizable only by Y direction. So I went ahead and did:  
SDL\_SetWindowMinimumSize(wnd, 100, 100);  
SDL\_SetWindowMaximumSize(wnd, 100, 200);  
But this applies only minimum size. I can still resize window as big as i want.  
But if I do this:  
SDL\_SetWindowMinimumSize(wnd, 100, 100);  
SDL\_SetWindowMaximumSize(wnd, 101, 200);  
It kinda works, but looks a bit off. Is this normal behavior? Is this a known bug?  
I’am using Windows and SDL 2.0.9.  
Cheers

Looks like it is indeed bug for me:

> SDL\_SetWindowMaximumSize(SDL\_Window \* window, int max\_w, int max\_h)  
> . . .  
> if (max\_w \<= window-\>min\_w || max\_h \<= window-\>min\_h) {  
> SDL\_SetError(“SDL\_SetWindowMaximumSize(): Tried to set maximum size smaller than minimum size”);  
> return;  
> }  
> . . .  
> }

There is no need in equals signs in this condition. Anyway i did some workaround based on SDL\_Window definition:

> SDL\_SetWindowMinimumSize(wnd, 100, 100);  
> //SDL\_SetWindowMaximumSize(wnd, 100, 200);  
> int hack = (int \*)wnd;
> 
> hack[10] = 100; // w  
> hack[11] = 200; // h

I know that this is very dangerous(not portable, version and compiler dependant) but I need the fix. I’am going to file this one as a bug to bugtracker.
