Detailed Description

Controls the time-related properties of the time stepper, according to the given input world time geometry.

A TimeNavigationController takes a TimeGeometry as input world time geometry and sets the properties of the associated stepper (BaseController). The time-related properties are:

• steps: the number of input time steps
• pos: the current time step / position of the stepper
• range: the time bounds for the slider (minimum, maximum)

The timestep controls the selection of a specific time point from the TimeGeometry. The TimeNavigationController generates ITK events to tell observers, like a BaseRenderer, when the selected timestep changes.

Example:

// Initialize the time navigation controller.
timeCtrl = mitk::TimeNavigationController::New();
 
// Set the required input world time geometry (a TimeGeometry::ConstPointer).
timeCtrl->SetInputWorldTimeGeometry(geometry.GetPointer());
 
// Set the time-related properties and send the information to the connected renderer(s).
timeCtrl->Update();

Vvisible navigation widgets can be connected to a TimeNavigationController, e.g., a QmitkSliceNavigationWidget (for Qt):

// Create the visible navigation widget (a slider with a spin-box).
QmitkSliceNavigationWidget* navigationWidget = new QmitkSliceNavigationWidget(parent);
 
// Connect the navigation widget to the time-stepper of the
// TimeNavigationController. For initialization (timestep, minimal and
// maximal values) the values of the TimeNavigationController are used.
// Thus, accessing methods of a navigation widget is normally not necessary,
// since everything can be set via the (Qt-independent) TimeNavigationController.
// The QmitkStepperAdapter converts the Qt-signals to Qt-independent
// itk-events.
new QmitkStepperAdapter(navigationWidget, timeCtrl->GetStepper());
