Is it possible to visualize the point cloud in QVTKOpenGLWidget?

Hello,@Paulo_Carvalho

I got the debug version of VTK, Qt and PCL and compiled the program in debug mode.
I run this vtk-example in debug mode and there is no error. But when I embed the render window of this example into the Qt main window and run in debug mode, I got the following error.

The inferior stopped because it received a signal from the operating system.
Signal name : SIGSEGV
Signal meaning : Segmentation fault

I also got the same error when I run the above bunny program.

regards,
AyeMoh
