Incorrect window size

[bandrewk]

Hello,

 

Leadwerks is not creating correctly sized windows. When setting the resolution to 800 x 600:

 

window = Window::Create("UISystem", 0, 0, 800, 600);

 

A window with the window size of 800 x 600 will be created, it seems correct at first but what I really wanted (and expected) this command to do is create a client area with the size of 800 x 600.

 

Leadwerks behavior:

 

Expected behavior:

 

Thank you.

This is a difficult situation because with Aero Microsoft broke the functionality of the Windows API to create a window of a specific size. Really. There's a bug report somewhere on this forum with a link to their actual documentation explaining this.

 

That's complete nonsense. Just use the AdjustWindowRect Windows API function. I fixed a related bug on another engine with the code below.

 

//Window
rectW.left	 = GetSystemMetrics(SM_CXSCREEN)/2 - nScreenWidth/2;
rectW.top	 = GetSystemMetrics(SM_CYSCREEN)/2 - nScreenHeight/2;
rectW.right	 = rectW.left + nScreenWidth;
rectW.bottom = rectW.top + nScreenHeight;
styleW		 = WS_POPUP|WS_CAPTION|WS_SYSMENU|WS_MINIMIZEBOX|WS_VISIBLE; //WS_OVERLAPPED | WS_SYSMENU | WS_MINIMIZEBOX;

AdjustWindowRect(&rectW,styleW,false);

Well, that's still not the right behavior. That creates a window with a specific client size. The Leadwerks function Windows::Create() is designed to create a window with a specified outer size. Which Windows can't actually do precisely, and it is a known bug in Aero. (Not sure if this is the same bug, but it probably is):

Since this is asking for new functionality different from the intended behavior, this is a feature request, not a bug report. It's probably a good idea to add an additional creation flag like Window::ClientCoords in the future, so that the function behaves in the way the OP suggested.

 

In the meantime, calling Context:GetWidth()/GetHeight() will return the correct client dimensions.

Alright, looking forward to that new functionality then.
