Summary: ChimeraX bug report submission → wrapped C/C++ object of type QScreen has been deleted

Happening during a make_current being called from the destructor of an in-window status bar

comment:2 by Tom Goddard, 4 years ago

Deleting a status bar tried to create a QOpenGLContext using a QScreen C++ object that had been deleted. Possibly the user had an external screen and it was removed, and later the tool was closed. It is strange and not so good that the QOpenGLContext for the status bar is being created when the statusbar is being deleted. That is because nothing was drawn to the status line so the opengl context was never created and the destructor is dumb and calls make_current() before deleting the Python context wrapper and that ends up trying to create the context. I should fix that. But that is not the bug. The bug is that the the context creation can use a QScreen that no longer exists. It is strange that the QOpenGLContext constructor takes a QScreen. It also takes a QWindow and that window is on some screen and can be moved between screens. So requiring the screen be specified seems like it would cause an inconsistency if the window is not actually on the screen specified. Need to study the QOpenGLContext documentation (and possibly source code) to see what it is using the QScreen for.

comment:3 by Tom Goddard, 4 years ago

The QOpenGLContext constructor optionally takes a QWindow but my code does not supply that argument. It does not take a QScreen -- that is set with QOpenGLContext.setScreen() and is used by the QOpenGLContext.create() call together with the pixel format to make the context. The code should certainly use the QWindow.screen() if available -- it won't be available of QWindow has not yet been mapped, that is when QScreen would be needed.

Fixed.

Creating context now uses the screen the window is on if the window has been mapped. If the window has not been mapped and the primary screen when the statusbar was created has been deleted we could still get this error. Also made deleting the Render instance not create a QOpenGLContext if it was not already created. Also made the statusbar delete the Render instance before the opengl context -- that was another bug.
