<div>Hi Imre,<br>
<br>
</div>
it sounds like you want to set a specific pair
of window/level values instead of<br>
</div>
interactively setting them by mouse movement.
vtkResliceImageViewer is<br>
</div>
a subclass of vtkImageViewer2 which has methods to
set window and level values:<br>
</div>
void SetColorWindow(double w)<br>
</div>
void SetColorLevel(double l)<br>
<br>
</div>
If you dont want the viewer's vtkInteractorStyleImage to
do window/levelling you<br>
</div>
can handle those events and process them yourself by
subclassing your own <br>
</div>
interactor style from vtkInteractorStyleImage.<br>
<br>
</div>

<br>
I have a question about the attributes when holding down the
left mouse button while moving the cursor up and down<br>
in the render window.<br>
<br>
Set up is a combination of QVTKWidget and
vtkResliceImageViewer:<br>
<br>
view = vtkSmartPointer<vtkResliceImageViewer><br>
<br>
...<br>
<br>
view->SetInputData(vtkImageData);<br>
ui->display->SetRenderWindow(view->GetRenderWindow())<br>
view->SetupInteractor(ui->display->GetRenderWindow()->GetInteractor());<br>
view->Render();<br>
ui->display->update();<br>
<br>
ui->display: QVTKWidget<br>
view: vtkSmartPointer<vtkResliceImageViewer><br>
<br>
Whenever I hold the left mouse button and move the cursor,
the displayed image becomes darker (while moving up)<br>
and brighter (while moving down) respectively.<br>
<br>
I want to set the attribute to a certain level. I guess I
have to override some events, but I need to know the
attribute that will be set / changed during the described
processes.<br>
<br>
Thanks in advance<br>
<br>
Imre<br>
