Hi all!

I'm developing a GUI application for a ARM9 based telephone. Presently I write codes and debug under Qt creator 2.1.0 at x86 Ubuntu host. I want to test the application with a conventional USB keyboard connected to a host and later implement all necessary hardware stuff for the embedded platform..

My application has a number of pages created by QStackedWidget. I switch between pages like Menu, Address Book, Parameters etc by pressing QPushButton's. A mouse works fine but I want to use a keypad of a PC-keyboard to handle the necessary logic of the application.

I have a few problems and need your assistance:
1) how should I implement an input system for my application because I need also to scroll letters inputed by a multiple numeric pressings (imaging a cell phone with a keypad, not touchscreen)? I mean if a user enters a Name or a Password he has only "0-9" keys and needs to enter "My_Password123" to some QLineEdit

2) as I have a number of pages with different widgets included how I should capture key events? I try to use keyPressEvent but it depends on a widget being focused, however I need to capture all key event independently to a widget focus.

In fact I can implement a little hack: don't use QWS_KEYBOARD variable and just open a device node "/dev/input/event0" and parse input events manually. This is very easy because Linux input system is trivial. Upon this scenario I don't understand how to translate my acquired events to an Qt-application readable format. In fact I need something like the suggested hack because all numbers have to be translated to letters..

This is my first Qt application and my customer craves for it
Please help!
