11 // JLH 02/01/2010 Created this file
12 // JLH 07/05/2011 Fixed model to not reset itself with each new row insertion
13 // JLH 07/07/2011 Added code to help the built-in keyboard based auto-search
14 // of the QListView class
15 //
16
17 // Note that we have to put in convenience functions to the model for adding data
18 // and calling reset() to tell the view(s) that the model has changed. So that much
19 // should be simple. According to the docs, we have to reimplement flags() in the
20 // QAbstractListModel subclass, but in the example given below they don't. Not sure
21 // if it's necessary or not.
