Maybe you're just missing a<br>
renderer->ResetCamera();<br>
<br>
If you're just viewing an image, have a look at the image viewer example in VTK/Examples/GUI/Qt/ImageViewer<br>

Ok, I added a style to my interactor in the following way:<br>
<br>
//code<br>
vtkRenderWindow *renderWindow = vtkRenderWindow::New();<br>
renderWindow->SetSize(550, 450);<br>
renderWindow->AddRenderer(renderer);<br>
vtkRenderWindowInteractor* inter = QVTKInteractor::New();<br>
renderWindow->SetInteractor(inter);<br>
vtkInteractorStyleImage* interstyle = vtkInteractorStyleImage::New();<br>
inter->SetInteractorStyle(interstyle);<br>
view->SetRenderWindow(renderWindow);<br>
//end code<br>
<br>
(where view = QVTKWidget)<br>
<br>
And, I still get the same results. Instead of a nice plot, I just get a blank white screen. Thoughts? Am I doing something wrong?<br>
<br>
Thanks,<br>

Interaction is handled by the interactor style classes.<br>

You can use an existing style, or make your own and give it to the<br>
interactor.<br>

I am able to create a 2d plot using a QVTKWidget, however I am<br>
unable to interact with that plot. I pretty much new to VTK,<br>
so I am kind of at a loss as to how to connect the vtk<br>
interactors and Qt. I have poked around a bit and noticed a<br>
QVTKInteractor class, but anything I do with that results in<br>
my 2d plot going away to be replaced with a blank white area.<br>
Below is the code that I am using. Just as a note, this is<br>
being done in a class that extends a QMainWindow.<br>
<br>
//snippet//<br>
<br>
<br>
view = new QVTKWidget;<br>
setCentralWidget(view);<br>
<br>
int DIM = 500;<br>
vtkDataArray *dataArray1 =<br>
vtkDataArray::CreateDataArray(VTK_FLOAT);<br>
dataArray1->SetNumberOfTuples(DIM);<br>
<br>
vtkDataArray *dataArray2 =<br>
vtkDataArray::CreateDataArray(VTK_FLOAT);<br>
dataArray2->SetNumberOfTuples(DIM);<br>
<br>
int t;<br>
for (t = 0; t < DIM; t++)<br>
{<br>
float x = t;<br>
float y = vtkMath::Random(0.0f,1.0f);<br>
dataArray1->SetTuple(t, &x);<br>
dataArray2->SetTuple(t, &y);<br>
}<br>
<br>
vtkFieldData *fieldData = vtkFieldData::New();<br>
fieldData->AllocateArrays(2);<br>
fieldData->AddArray(dataArray1);<br>
fieldData->AddArray(dataArray2);<br>
<br>
vtkDataObject *dataObject = vtkDataObject::New();<br>
dataObject->SetFieldData(fieldData);<br>
<br>
vtkXYPlotActor *plot = vtkXYPlotActor::New();<br>
plot->AddDataObjectInput(dataObject);<br>
plot->SetTitle("Plot");<br>
plot->SetXTitle("X-Axis");<br>
plot->SetYTitle("Y-Axis");<br>
plot->SetXValuesToValue();<br>
plot->SetWidth(0.9);<br>
plot->SetHeight(0.9);<br>
plot->SetPosition(0.05, 0.05);<br>
plot->LegendOn();<br>
plot->PickableOff();<br>
plot->PlotCurvePointsOn();<br>
plot->PlotCurveLinesOff();<br>
<br>
plot->SetDataObjectXComponent(0, 0);<br>
plot->SetDataObjectYComponent(0, 1);<br>
plot->SetPlotColor(0, 1.0, 0.0, 0.0);<br>
plot->SetPlotLabel(0, "My Label");<br>
//plot->GetProperty()->SetColor(0.0, 0.0, 0.0);<br>
<br>
vtkRenderer *renderer = vtkRenderer::New();<br>
renderer->SetBackground(0, 0, 0);<br>
renderer->AddActor2D(plot);<br>
<br>
vtkRenderWindow *renderWindow = vtkRenderWindow::New();<br>
renderWindow->SetSize(550, 450);<br>
renderWindow->AddRenderer(renderer);<br>
// vtkRenderWindowInteractor* inter = QVTKInteractor::New();<br>
// renderWindow->SetInteractor(inter);<br>
view->SetRenderWindow(renderWindow);<br>
<br>
//end-snippet//<br>
