[vtkusers] QVTKWidget and MacOS problems

[Nick Patterson]

Dear all,

To demonstrate the issue that I am having, I will refer to the FourPaneViewer example that is bundled with VTK. This example replicates the issue that I am experiencing in my own application but only on the MacOS platform.

The attached image shows that the CT renders in the windows, but noticeably they only occupy the botton left corner of the QVTKWidget. This is not seen when compiling this example on Linux, but is a problem on MacOS.

The ouput on the command line that accompanies this behaviour is:-

All of this behaviour also affects mouse interactions (i.e. if I try to maniulate the cross-hairs, the mouse position is completely off.

Can anyone provide advice on the this, specifically for MacOS?

Regards, Nick.
