I'm trying to make a small window that is able to dynamically
follow the text caret (the little "I" shaped cursor) while typing.
In most cases, the text caret is owned by other application.
Therefore, I'm looking for a solution which is able to tell where
(x, y) is the text caret system wide. After spending hours on
searching, it seems to me that there is no straight-forward way to
do it (like locating the mouse cursor by using GetGlobalMouse() or
[NSEvent mouseLocation]). Any suggestion or point to right docs
will be highly appreciated.
This is the sort of thing that an input method would do; try looking
at the documentation for input methods, e.g. the TSM reference
material. There probably are examples available too.
The alternative would be to use the accessibility APIs.
