Bug 3567

Summary: SDL_MaximizeWindow doesn't respect the WindowMaximumSize
Product: SDL Reporter: Rene <king-sora>
Component: videoAssignee: Ryan C. Gordon <icculus>
Status: WAITING --- QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: adam
Version: 2.0.5   
Hardware: x86_64   
OS: Windows 7   
Attachments: A WindowsForms App with a window with max size 500x500

Description Rene 2017-01-24 12:11:51 UTC 
If I create a window with the following flags:

SDL_CreateWindow(title, x, y, width, height, 
SDL.SDL_WindowFlags.SDL_WINDOW_ALLOW_HIGHDPI | 
SDL.SDL_WindowFlags.SDL_WINDOW_OPENGL | 
SDL.SDL_WindowFlags.SDL_WINDOW_HIDDEN | 
SDL.SDL_WindowFlags.SDL_WINDOW_RESIZABLE);

Then set the maximum size to: 400x400 with:
SDL_SetWindowMaximumSize(handle, 400, 400);

Then deside to maximize the window with:
SDL_MaximizeWindow(handle);

And then show it, the window will be maximized over the whole screen although the maximum size should be 400x400.
But when I minimize the window and then restore the window, its has the 400x400 size, even in maximized mode.

I've figured out, that if the user resizes / maximized / minimzes the window manually, the MaximumSize of the window will be respected. Just if I set the WindowMode in my code (SDL_MaximizeWindow(handle)) the maximimSize wont be respected.

Rene, I'm not entirely sure this is a bug. Every application I've seen covers the whole screen when you maximize it, unless it's doing special docking behavior. What is your use case here?

Ryan, what happens on other platforms?

Well, I dont know any usecase, but on the Windows Platform a maximized window can have a maximal size.

I've added a attachment (a WindowsForms application with max size 500x500) to this bug.
