Hi Kevin,
after loading your 4D image, you can check dimensions and timesteps to ensure
it is 4D.
If it is loaded correctly, then the mistake is propably in your signal/slot
connections:
Try this:
mitk::SliceNavigationController* timeController =
GetActiveStdMultiWidget()->GetTimeNavigationController();
if (timeController)
{
m_TimeStepper = new QmitkStepperAdapter(m_Controls->m_SliderTime,
timeController->GetTime(),
"sliceNavigatorTimeFromSimpleExample");
m_Controls->m_SliderTime->setEnabled(true);
}
else
{
m_Controls->m_SliderTime->setEnabled(false);
}
You need to have the member variable:
QmitkStepperAdapter* m_TimeStepper;
Regards,
Bastian

Betreff: [mitk-users] MRI 3D+t : time slider doesn't work
Hi,
I try to visualize 3D images + T.
To create a slider linked to time steps, I used QmitkSliderNavigatorWidget and
QmitkStepperAdapter classes. But when I move the slider, the image does not
update.
QmitkSliderNavigatorWidget *sliderNavigatorTime = new
QmitkSliderNavigatorWidget(controlsParent);
new QmitkStepperAdapter(sliderNavigatorTime,
sliceNaviControllerTime->GetTime(),"Time");
I used the function LoadDicomSeries() to sort and open 3D + t.
m_ResultNode =
mitk::DicomSeriesReader::LoadDicomSeries(fileNameList,true,true,0);
m_ResultImage = dynamic_cast<mitk::Image*>(m_ResultNode->GetData());
The image has four dimensions and the slider has as the same count of steps as
there is time steps in the image.
I have no idea why the slider is not working. Any thought ?
Thank you for your help, Kevin B.
