One particularity in the relationship of UNO controls and their models must be considered. Following the principles of the MVC paradigm all changes applied to the control model are directly propagated to the control and (its peer object). However, conversely not all changes applied to the control will notify the model. The general rule is that whenever an attribute of a control is modifiable by the user, a change of this attribute is also propagated to the model. The following table sums up all methods which invocation at UNO controls is propagated to the respective control model. The controls and interfaces are described in detail in the following sections.
