Hi, I have already tried rotating the GUI, but it doesn't work. When you enter the mouse over the 3D TabWidget, you can see the message "Widget::enter()" on the console log. But, if you do the same with the TabWidget which is inside the HUD camera, you can't see any message. We think that the problem is in the method called "computeExtentsPositionInLocalCoordinates" of the Widget class (Widget.cpp file) on lines;
498 matrix.postMult(camera->getViewMatrix()); 499 matrix.postMult(camera->getProjectionMatrix()); because it uses the matrices of the 'default' camera instead of the HUD camera's matrices. We've replaced the two lines before with the next line. In this way, it detects the mouse over the TabWidget which is inside the HUD camera, but when I click on the tabs it doesn't work. We could write this line because we know the projection matrix of our HUD camera. matrix.postMult(osg::Matrix::ortho2D(0, 1400, 0, 760)); Thank you.
