Need help with RenderBox

Hi,

The renderbox demo is so awesome and it compiles well. But when I use it in my project, there is only a blank canvas showing nothing. I've searched through the board but found noting helpful.

Could anyone help me figure out how to get the render box work?

Thanks a million!


Below is my code, looks pretty same as the demo code.

void MyPhysicsLab::createRenderBox( void )
{
wraps::RenderBox gRenderBox;

const MyGUI::IntSize& size = MyGUI::RenderManager::getInstance().getViewSize();


MyGUI::Window* window = MyGUI::Gui::getInstance().createWidget<MyGUI::Window>("WindowCS", MyGUI::IntCoord(size.width - 10 - 300, size.height - 10 - 230, 300, 230), MyGUI::Align::Right|MyGUI::Align::Bottom, "Overlapped");
window->setCaption("Camera View");
window->setMinSize(MyGUI::IntSize(100, 100));
MyGUI::Canvas* canvas = window->createWidget<MyGUI::Canvas>("Canvas", MyGUI::IntCoord(0, 0, window->getClientCoord().width, window->getClientCoord().height), MyGUI::Align::Stretch);

gRenderBox.setCanvas(canvas);
gRenderBox.setViewport(mCamera);
gRenderBox.setBackgroundColour(MyGUI::Colour::Black);

}


And here is the MyGUI.log

OMG, just after I posted this topic, I realized that I should use pointers. Problem solved!
