- the children of the treeitem
- the associated prefs widgets
- the documentview with all the prefs widgets in it
- a saveChanges action
- a revertChanges action
- a redraw view action
- the children action should generate a list of the treeitems children (to be used by VLCPrefs datasource)
The class is sort of a mix of wxwindows intfs, PrefsTreeCtrl and ConfigTreeData
