@class wxCaret
@wxheader{caret.h}
A caret is a blinking cursor showing the position where the typed text will
appear. Text controls usually have their own caret but wxCaret provides a
way 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.
