I cannot find any information how to solve the following problem:
I've built the example of using AIS with Qt . It is done similar to what is given in ros/samples, but even simpler - Widget is taken from CommonViewer class - this is the main thing. It is created just as central widget in the main window.
I can build and start the example just fine, but the problem is that the viewer is blinking when I reside the window and even worse - it may stay gray (or partly gray).
I checked, that I set
(actually even twice - as it is done twice in the example) during the creation of the viewer widget, but this does not help.
I guess, that this is some standard thing, but I cannot figure out how to solve this. Any hints are highly appreciated.
I work with OCCT660 and Qt 5.1
Thanks in advance.
