[vtkusers] vtk + qt delay in corner annotation?

[Ale]

Hi,

I try. Since the this->renderer is the result of QVTKWidget GetRenderWindow() function, I simply add this piece of code to set the annotator in the constructor of my class (which instantiate the QVTKWidget within a frame) :

    this->annotator = vtkSmartPointer<vtkCornerAnnotation>::New();

    this->annotator->SetLinearFontScaleFactor( 2 );
    this->annotator->SetNonlinearFontScaleFactor( 1 );
    this->annotator->SetMaximumFontSize( 13 );

    this->annotator->GetTextProperty()->SetColor( 1,1,1);
    this->annotator->SetText( 0, "<slice_and_max>");
  
    this->renderer->AddActor(this->annotator);
    this->renderer->ResetCamera();

I found out that if I left-click several times to the current slice, the <slice_and_max> updates, otherwise it keep to show a wrong value...

I hope this help...
Thanks,
Ale
