/** \file mouse.h

* \brief Header: Hight-level mouse API.
|
|
*
|
|
* This is a thin layer over the low-level mouse protocol in lib/tty/mouse.h.
|
|
* The latter is oblivious to the regions on the screen and is therefore a
|
|
* bit hard to use in widgets. This layer translates the low level Gpm_Event
|
|
* into something that's easy to work with in widgets.
