Carets
A caret is a flashing line, block, or bitmap in the client area of a window.
The caret typically indicates the place at which text or graphics will be
inserted. The following illustration shows some common variations in the appearance
of the caret.
Because only one window at a time can have the keyboard focus or be active,
there is only one caret in the system. Generally, each window that accepts
keyboard input must create the caret when it receives the keyboard focus and destroy
the caret when it loses the keyboard focus. For more information on keyboard
input, see Keyboard Input.
An application written for Microsoft® Windows® can create a caret, display or hide it, relocate the caret, and change its
blink time.
