qvtkwidget interaction with a slider

Question

I have a problem with qvtkwidget. I have a cube with the vtkimageplanewidget and i already made the connection between the sliders and them, but I want the slider to change also when I change the planes with the mouse in the qvtkwidget.

How can i do that?

Here's how I connected the slider eith the planes.

SLOT:

void planevolume::SplaneXpixel()
{
    double xvalue=ui->Slider->value();
    planeX->SetSliceIndex(xvalue);
    ui->qvtkWidget->update();
}

and then:

  connect(ui->Slider, SIGNAL(valueChanged(double)), this, SLOT(SplaneXpixel()));

What about the opposite? I tried:

SLOT:

void planevolume::planeXSpixel()
{
    double xvalue=planeX->GetSliceIndex();
    ui->Slider->setValue(xvalue);
    ui->qvtkWidget->update();
}

and then:

connect(ui->qvtkWidget, SIGNAL(mouseEvent(QMouseEvent*)), SLOT(planeXSpixel()));

but it won't work, can anyone help me?

What won't work? I'd suggest posting a fully compilable example, and explaining what is going wrong. — David Doria

I believe you are looking for vtkEventQtSlotConnect. Here is an example: http://www.vtk.org/Wiki/VTK/Examples/Cxx/Qt/EventQtSlotConnect
