Trouble getting Ogre window to display properly.

[ProgrammerAtHeart3344]

I've been trying to follow tutoria;ls and experiment setting up Ogre with QtGUI but i've run into some problems.
first, the Widget is like 100x30 no matter what size i make it, and i find it funny that if i pick Direct3D9 renderer i get openGL if i pick OpenGL i get D3D9.........
Here's the output of the window when i run the program:

now here is my code for it:

void CRenderer::DrawScene()

}

How i'm calling this class:

@

CRenderer* Win = new CRenderer(w.getCentral());

try
{
Win->createRenderer("OpenGL");
}
catch(Ogre::Exception &e)
{
MessageBoxA(NULL,e.getFullDescription().c_str(),"",MB_OK);
}

Win->DrawScene();

w.show();

hopefully someone can help me other wise i'll ask on the Ogre3D forum, i'm not sure if this is an Ogre problem or a QT4 widget problem (Meaning i might not know how to set it up\ right, which is possible......)
