TreeView and TreeViewItem and currently a little messes up in its API
|
|
because of ResultView. ResultView class was to be the base interface to
|
|
a TQTable and a TQListView, but the APIs are a little diferent... then I realize
|
|
that a TQTable view isn't needed at all so some day I will clean this up.
