Cursors that can be used

ArrowCursor, UpArrowCursor, CrossCursor, WaitCursor, IBeamCursor, SizeVerCursor, SizeHorCursor SizeBDiagCursor, SizeFDiagCursor, SizeAllCursor, BlankCursor, SplitVCursor, SplitHCursor PointingHandCursor, ForbiddenCursor, OpenHandCursor, ClosedHandCursor, WhatsThisCursor, BusyCursor, BitmapCursor

Limitation

The cursor can change appearance depending on the used Workbench, he must repeat the operation.
The cursor can be subtituer to the other sliders (ex: expansion of a window, corner...).
The grid is permanent.
