25 /* VLCPrefs manages the main preferences dialog
26 the class is related to wxwindows intf, PrefsPanel */
27 /* VLCTreeItem should contain:
28 - the children of the treeitem
29 - the associated prefs widgets
30 - the documentview with all the prefs widgets in it
31 - a saveChanges action
32 - a revertChanges action
33 - an advanced action (to hide/show advanced options)
34 - a redraw view action
35 - the children action should generate a list of the treeitems children (to be used by VLCPrefs datasource)
37 The class is sort of a mix of wxwindows intfs, PrefsTreeCtrl and ConfigTreeData
39 /* VLCConfigControl are subclassed NSView's containing and managing individual config items
40 the classes are VERY closely related to wxwindows ConfigControls */
