There was a problem hiding this comment.
Gave this a try with some simple image examples and it worked as expected for me. Havn't tried with the markers in #21, but can do that after this gets merged. Looks good to me.

…visible
The visibilitychanged slot currently updates the title regardless of the visibility. We are seeing a crash when the viewer is shut down and a signal is sent to the visibilitychanged slot. That executes some code which causes a segfault in the python process[1]. This PR changes the visibility changed slot to only update the title bar if the widget is visible.
