easymodel.cascade

This module provides classes for viewing a multi-level hierarchy. Imagine you have a treemodel and a combobox for each level which only shows the part of the hierarchy beneath the selected parent index in the higher-level combobox. So each time the user selects an entry in the combobox, all levels beneath automatically get updated and change their root to the selected index.

The main base class is AbstractCascadeView which handles the logic for automatically updating the lower levels. Each level of the hierarchy is displayed by a AbstractLevel. A level could be a single combobox, a listview or any other widget that you want to use.

There are also some simple, useful implementations:

• ComboBoxCascadeView
• ListCascadeView
