Detailed Description

MRML layout manager that instantiates the Qt widgets and layouts from the layout node and the view nodes in the scene. The management (creation, configuration and deletion) of the view widgets are delegated to qMRMLLayoutViewFactory. Example to change a default factory:

qMRMLLayoutSliceViewFactory* mrmlSliceViewFactory =
MySliceViewFactory* mySliceViewFactory =
new MySliceViewFactory(app->layoutManager());

You can also register ctkLayoutViewFactories that are not related to MRML view nodes.

Member Typedef Documentation

◆ Superclass

typedef ctkLayoutFactory qMRMLLayoutManager::Superclass

Superclass typedef.

Definition at line 92 of file qMRMLLayoutManager.h.

Property Documentation

◆ enabled

bool qMRMLLayoutManager::enabled

This property controls whether the layout manager reacts to layout node changes or note. When enabled (default), the layout is updated each time the layout node is modified and when the scene leaves batch-process state. It can be useful to temporarily disable the manager when loading a scene, it could otherwise change the layout.
