/**

@class wxCaret
|
|
|
|
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.
