Combine Ogre-Next on qt with others QOpenGLWidget on same iu.

[promero]

Hi,

I try to embed Ogre-next on Qt6 ( using opengl ). Everything works fine if any QOpenGLWidget are present and ogre-next is the only one.

I have generated a class with ogrenext functions that can work passing wId from a QOpenGLWidget and it is posible to render from ogre to this qwidget, others QOpenGLWidget are present too.

The main problem is that I can't control the paintgl function and if I use makecurrent I get a black screen over ogre, If I don't use it, I can see ogre-next rendering ( using Qtimer ) but as soon as I focus on another QOpenGLWidget , ogre-next render became black.

I guess problem is because ogre use internal openglcontext and Qt others..

I have checked the possibility to use "externalGLControl","currentGLContext","externalGLContext" without sucess.

To resume: i wantot use ogre-next inside Qt6, working with opengl together with others QOpenGLWidget ,and if it is posible to share textures between them, generating a texture on a QOpenGLWidget , and using the texture on ogre using the textureID.

Is it posible, or I will have to use ogre ( no next ) to work together with Qt ??

I would apreciate some ideas about it

Thanks !!!

Getting two libraries using OpenGL at the same time and cooperate can be tricky, but not impossible.
See how Gazebo does it which uses both Ogre-Next and Qt6.

Gazebo creates a dummy 1x1 window that is hidden, acts as the "main" window and remains available for the lifetime of the application. This makes it easier to work with Qt if you need more than one window.
