How to scale or stretch RenderWindow to fit into a Qt QWidget window?

[ccleung6]

Hi,

I follow the SFML tutorial to subclass a QWidget from SFML RenderWindow.
But I have no idea how to scale the render window when the QWidget window resizes.

Assume the render window is 640 * 480, the QWidget window is resized to 800 * 600,
is that I need to resize render window to 800*600 and scale everything by a scaling factor for drawing?

I have no idea how SFML and Qt are connected but to resize a sf::RenderWindow you simply create a new one, i.e. call the create(...) function on the render window object.

You should have nothing to do. What happens currently?

The problem is when the Qt window resizes, the inner sf::RenderWindow remains the same size, it won't scale or stretch all all.
But I want it to scale/stretch to fit the container window size.

Any idea to do that?

It should work automatically. But if it doesn't, try to call window.setSize(...).
