Rather, rendering targets an OpenGL texture and is controlled + through QQuickRenderControl. + + The cube is rendered directly with OpenGL, using Qt Gui enablers such as + QWindow, QOpenGLContext, QOpenGLShaderProgram, and QOpenGLFunctions. The + cube is textured with the texture that the Qt Quick render pass outputs to. + + In addition, basic input event forwarding is also demonstrated. When holding + down the left mouse button, the background \l Rectangle color is altered via + QML bindings. Similarly, holding down a key on the keyboard changes the + color as well. This proves that the "fake" events sent from the application + (generated based on events from the on-screen QWindow) are forwarded and + processed within the Qt Quick scene. */ |
