QT + SDL for games?

[Codepoet]

You did not write what kind of game you plan. If you want something with 3D you should learn OpenGL which you can use with SDL. AFAIK you can't render with Qt in a framebuffer. You simply have a special Qt Widget in which you can display your framebuffer.
Maybe you want something like http://libufo.sourceforge.net That should be easier to integrate, it even has a sample SDL application. Do you know the http://nehe.gamedev.net tutorials?

personally I would suggest Ogre 3D Engine

Irrlicht is much better and the integration may not be that hard since an example demonstrate how to render inside a native window.

SDL was chosen because we don't wan't to lock out people with low-end machines, without 3D hardware. The game is 2D and uses an isometric tile-based view.
So the QT OpenGL makes use of hardware acceleration?

[Codepoet]

Yes, Qt Open GL is hardware accelerated. Otherwise you probably wouldn't use it

Hi,

when you mentioned SDL and isometric tiles, I immediatley think of Kyra. Its C++ built on top of SDL. It has specific code for isometric tiling.

I have a couple of unfinished games written in Kyra, and thought the API was easy, and the engine very powerful. But, if you're well into SDL already, this comment wont help
Kyra has some basic widgets built in, enough for a simple UI, but obviously its no Qt and not intended to be.

sorry if I'm getting off-topic, I love Qt for everything else, honest...

all the best,
barry

I'm making SDL-based game now. Some notes (my game is OpenGL-based)
I thought about making it run inside Gl widget in Qt app.. But then thought it would be slow.
Qt has nice classes to work with network, Qt has a great QString and other container classes. Maybe I'll use them linking to QtCore... But STL is not so bad, and parts of my app are from NVidia SDK that uses STL a lot.
The main code is OpenGL + NV_linear

Could you explain how would it be slow? QGLWidget uses normal OpenGL context to render its contents, being wrapped into a Qt widget shouldn't make it slower.

I mean that application based on Qt is slower than SDL-based application. AFAIK, Qt's event loopis more complex than event loop in SDL.

Take a look at its sources It's soooooooo complex!
