Keyboard hook [C++]

[SubArrin]

Hi!
I'm writting application similar to AutoHotKey for Windows. First of all I need to know, which keys was pressed in system. For Windows it is so easy (some time ago I even wrote keylogger for Windows - of course for training, I used it only in my computer). I was googling for something like this for Linux i I didng find anything.

The best I found was XSelectInput but I need something like this for many windows. If some appliaction are avoiding it becouse of security reasons it's OK - I can live with it
I think, none of Linux users would install something that can stole their passwords, so if You know how to do this for all appliaction I will be glad. For example I can think about some hotkeys in my internet browser, but this is application where are users are writting the most passwords.

I want to write it for Gnome first. Then, if I would make good appliaction I want to extend it for KDE and maybe another.

I'm sorry for my English - I'm still learning.

if you are looking to do it for gnome at first, you should take a look at GTK, since that is what gnome uses

KDE uses QT

the regular X window programming will work on anything with X, but it may be more cumbersome

The most appropriate means to do this consistently for all keyboard input in the system would be to install a kernel module that would intercept the keyboard interrupts, then pass the data to the normal user-space code as well as your user-space code that will do something special with it.
