	10	@class wxCaret
	11
	12	A caret is a blinking cursor showing the position where the typed text will
	13	appear. Text controls usually have their own caret but wxCaret provides a
	14	way to use a caret in other windows.
	15
	16	Currently, the caret appears as a rectangle of the given size. In the
	17	future, it will be possible to specify a bitmap to be used for the caret
	18	shape.
	19
	20	A caret is always associated with a window and the current caret can be
	21	retrieved using wxWindow::GetCaret(). The same caret can't be reused in two
	22	different windows.
