[vtkusers] vtk + qt delay in corner annotation?

[Ale]

Hello,

I noticed a strange behavior in my qt+vtk application. I set and vtkImageViewer2 into a QVTKWidget and a set of corner annotations within. One of the annotation represents the "<slice_and_max>" property. If I increase the slice, the annotation didn't update it self immediately, I have to lost focus on my app and the regain it to see the "repaint" and the update of the annotation. Why?

Thanks,
Ale
