Hi everyone,
I've recently started using Ogre and I'm really enjoying it. I'm currently working on embedding the render window into my Qt application. I found OgreApplicationContextQt and migrated the BasicTutorial code into it, then added some Qt widgets. The program worked fine, except that the Ogre window was located outside the Qt window.
I tried adding the following line of code:
Code: Select all
container->createWindowContainer(window);
However, after adding this line, the Ogre window disappeared.
I also tried calling startTimer() as suggested in the documentation, but it didn't work. Additionally, I attempted to write some code in timerEvent after finding it in the source code, but that didn't work either.
Could anyone please help me figure out what I did wrong?
Ogre Version: 14.2
