Detailed Description

Register widgets for questions.

This is a service interface. Obtain a pointer to its single instance via GetInstance().

Each QmitkQuestionWidget subclass must be registered by calling Register(), which is typically done in the module activator class. After QmitkQuestionWidget subclasses are registered, instances of them can be created with Create() based on their matching type of Question.
