[vtkusers] Mouse cursor disappears when rendering

[Maurice Samulski]

Hi All,

I've build a QT4.1 / VTK5.0 application with the QVTKWidget and I experience
the following problem:

When the mouse cursor is on a rendering object, the mouse cursor disappears
after the rendering. The mouse cursor returns by moving the mouse, but it
will leave a incorrectly rendered block. That block has the size of the
mouse cursor and shows the image before rendering. I have this problem only
when I compiled the application under SuSe 10.1 linux. If the same
application is compiled under Windows, this effect does not occur.

A "dirty" solution which works for now is:

interactor->HideCursor();
renderWindow->Render();
interactor->ShowCursor();

However, I would appreciate any suggestions that could prevent this effect
from happening. Thanks all for your time.


Sincerely,

Maurice
