Detailed Description

controller that manages the positioning and stacking of QmitkOverlays

This controller manages all QmitkOverlays of one QmitkRenderWindow.

When constructed, it creates one QWidget for each possible display-position and sets the appropriate attributes and layouts.

It is possible to add new Overlays using AddOverlay( QmitkOverlay ). This overlay will be added to the correct Widget according to its destined position (stored in QmitkOverlay). If this widget already holds an overlay, the layer-property is taken into account. If no layer has been set, the overlay will be appended at the end.

It is possible to set the visibility of all overlays at a time using SetOverlayVisibility(bool).

RenderWindow specific properties can be set using the internal mitk::PropertyList. This propertyList and the 'default' propertyList of the RenderingManager will be concatenated before the overlay is set up. If one property exists in both propertyLists, the one in the QmitkOverlayController will be used!

Member Function Documentation

◆ AddOverlay()

void QmitkOverlayController::AddOverlay ( QmitkOverlay * overlay )

adds an instance of QmitkOverlay to the RenderWindow

This method adds the given QmitkOverlay as a sub-widget to the registered RenderWindow. It will be added to the correct position in the RenderWindow as it's defined by the overlays position-variable. The layer-property will only be considered if necessary.

◆ AdjustAllOverlayPosition

void QmitkOverlayController::AdjustAllOverlayPosition ( )

slot

adjusts the position of all overlays to the position of the RenderWindow

This method updates the position of all Widgets according to the position of the RenderWindow and the extend of the overlays.
