How to know if any CEGUI window(s) is focused or clicked

[marty188586]

Hello,

I am new to CEGUI.
I'm grograming a game, therefore I need a GUI system. I choose CEGUI (SDL input).
The question I met now is that inorder to input non-English langusges, I need IM(input method) support. However IM support is only needed when a CEGUI window is focused. How could I kow if any window is focused or not? or How do I know have I clicked on any window when my mouse clicked?

Thanks for any help.

You must notify your CEGUI::System object about mouse move, mouse up etc. and handle this events. See manuals and tutorials, there writed in detail.
