10 | ||
11 | A caret is a blinking cursor showing the position where the typed text will | |
12 | appear. Text controls usually have their own caret but wxCaret provides a | |
13 | way to use a caret in other windows. | |
14 | ||
15 | Currently, the caret appears as a rectangle of the given size. In the | |
16 | future, it will be possible to specify a bitmap to be used for the caret | |
17 | shape. | |
18 | ||
19 | A caret is always associated with a window and the current caret can be | |
20 | retrieved using wxWindow::GetCaret(). The same caret can't be reused in two | |
21 | different windows. | |
