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. | |
