/* ==========================================================================
	Class :			CExListBox

	Author :		Johan Rosengren, Abstrakt Mekanik AB

	Date :			2004-06-14

	Purpose :		"CExListBox", derived from "CListbox", adds dragging to a 
					listbox. It also sends registered messages to the owner
					when DEL is pressed, when a line is double clicked and 
					when the selection is changed (the last two as the 
					dragging kills the normal notification mechanism).

					The class also sets the tab-position to half the 
					horizontal width, and automatically sets the listbox 
					scrollbar width when adding a string.

	Description :	Handles the mouse messages to allow dragging. Sends 
					registered messages to the parent for selected events.
					Hides "AddString" (as it is not virtual) for scrollbar 
					adjustments.

	Usage :			Use as any "CListbox".
