@class wxCaret
@wxheader{caret.h}
A caret is a blinking cursor showing the position where the typed text will
appear. The text controls usually have a caret but wxCaret class also allows
to use a caret in other windows.
Currently, the caret appears as a rectangle of the given size. In the future,
it will be possible to specify a bitmap to be used for the caret shape.
A caret is always associated with a window and the current caret can be
retrieved using wxWindow::GetCaret. The same caret
can't be reused in two different windows.
