centralWidget qmainwindow
Message 1 in thread
Hello
I have strange problem with graphicsview and qmainwindow widget. My
graphicsview widget is central widget of widget which is inherit after
qmainwindow. I want to create new qgraphicsview to switch with first but
i still have only Segmentation fault.
Even if I call QWidget * widget = centralWidget();
I get Segmentation fault.
What it could be?

Please provide a complete, small example that shows the problem, neither
from your description nor the code-line its visible what your problem
might be.

Sorry for such delay to answer. Error was in the other place of course.
In application I have Two independent widows. To be true, the second
window, when the dimension of central widget in first window is set is
making by constructor when one of params is pointer to the first window.
It's all be goof but I call the second window form singleton designed
pattern, which if no second window was constructed before, it making it.
And this was bad because then it was making with NULL pointer to the
first
window :)
Anyway, thank for your response.
