The wxListCtrl can show lists of items in four different modes:
which item. Each image in an image list can contain a mask, and can be made out
of either a bitmap, two bitmaps or an icon. See ImagList.h for more details.
- Notifications are passed via the wxWindows 2.0 event system, or using virtual
- functions in wxWindows 1.66.
+ Notifications are passed via the wxWidgets 2.0 event system, or using virtual

See the sample wxListCtrl app for API usage.
