	10	@class wxCaret
	11	@wxheader{caret.h}
	12
	13	A caret is a blinking cursor showing the position where the typed text will
	14	appear. The text controls usually have a caret but wxCaret class also allows
	15	to use a caret in other windows.
	16
	17	Currently, the caret appears as a rectangle of the given size. In the future,
	18	it will be possible to specify a bitmap to be used for the caret 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
	22	can't be reused in two different windows.
