I have a program that has two top level OpenGL widgets. I'm having problems creating shader programs and sharing them between the windows. The shaders work prefectly in one window, but not in the other. Previously I've used QGLWidget, but now I'm trying to upgrade it to QOpenGLWidget. With the old system, I had no problems sharing everything between the top level widgets.
I'm using QCoreApplication::setAttribute(Qt::AA_ShareOpenGLContexts) before creating the QApplication. I've also used QOpenGLContext::areSharing() to compare the contexts and they are supposedly being shared. >From the documentation for QOpenGLContext, it states: Resources, such as framebuffer objects, textures, and vertex buffer objects can be shared between contexts. In that list of resources, it doesn't list shader programs. Can they be shared or are they treated differently? I found this forum post http://forum.qt.io/topic/51764/2-qopenglwidget-shared-context which is asking the same thing I am. Can anyone lend some insight? -- Lorne Sturtevant Sum Ergo Cogito _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
