Log:
2008-02-07 Aaron Bockover <abock gnome org>
* src/Core/Hyena.Gui/Hyena.Data.Gui/ListView/ListView.cs:
* src/Core/Hyena.Gui/Hyena.Data.Gui/ListView/ListView_Header.cs:
* src/Core/Hyena.Gui/Hyena.Data.Gui/ListView/ListView_Interaction.cs:
* src/Core/Hyena.Gui/Hyena.Data.Gui/ListView/ListView_Model.cs:
* src/Core/Hyena.Gui/Hyena.Data.Gui/ListView/ListView_Rendering.cs:
* src/Core/Hyena.Gui/Hyena.Data.Gui/ListView/ListView_Windowing.cs:
Split ListView.cs into several partial class implementations so
maintaining and reading the code is a lot easier since this is a huge
class; lots of cosmetic cleanup
* src/Core/Hyena.Gui/Hyena.Data.Gui/RowActivatedHandler.cs: Moved to
its own file from ListView.cs
