IOManager Class
|
|
===============
|
|
|
|
.. note::
|
|
This page is still WIP.
|
|
It only covers the function of the IOManager class vaguely. In reality, the
|
|
IOManager unit contains quite some classes, each with a (slightly) different
|
|
function. There are not yet documented. (Perhaps BenLand100 can do this?)
|
|
|
|
The IOManager class manages the core functionality for retreiving Window data,
|
|
such as the actual pixel data and the position and dimension of a window.
|
|
|
|
The main purpose is to form a cross platform class to retrieve window
|
|
information, press and poll mouse buttons and to press and poll keyboard keys.
|
|
|
|
The IOManager is the only class that should use platform (or operating system)
|
|
specific calls; this is all abstracted by the IOManager class.
|
|
|
|
To achieve this, several abstract classes are defined by the IOManager class.
|
|
Every operating system (or window system) needs it's own implementation of the
|
|
``TWindow_Abstract`` class. We wrote one for both Linux and Windows.

Offscreen image capturing
|
|
-------------------------
|
|
|
|
On Linux, offscreen image capturing is possible when compositing is turned on.
|
|
With compiz, this is turned on by default. Other windows managers like Metacity
|
|
and KWin can turn this on. When enabled, Simba can capture images from windows
|
|
that are below others. Minimized does not work. It is also possible to turn on
|
|
Compositing for specific X11 Windows with an api call, but this is currently not
|
|
implemented.
|
|
|
|
The status on Windows is unknown.
|

Silent Input
|
|
------------
|
|
|
|
So what is Silent Input?
|
|
We define Silent Input as methods to manipulate the user's mouse and keyboard,
|
|
without visually using them. So what does this mean?
|
|
|
|
This basically means that you will still be able to use your mouse while
|
|
the MML is performing mouse operations on your targetted window/client.
|
|
|
|
However, silent input is very hard to implement, and often hardly supported
|
|
by host operating systems. Often silent mouse or keyboard input is simply
|
|
ignored. So in general it is advised to stick to non silent input.
