  This sounds like a Linux problem rather than a Qt problem.

  Isn't it the Linux Keyboard Driver that's effectively "pairing"
  the keyboards? That is, by the time Qt gets the I/O, the
  input from the two keyboards is already deliberately

  There's probably already some Linux setup parameter
  somewhere that can un-do this, or, as is always true, if
  the feature isn't already there, you can hack the Linux

  This page seems to be a nice general reference:


  This page seems to go pretty directly to your question:


  Together, they may give you some ideas. Once the Linux problem
  is solved, *THEN* it can become a Qt problem.

Subject: [Qt-creator] How to take inputs from two keybaords for different dialog boxes

Hello All,

I am using Qt from some-time now. But stuck with one requirement as explained below. Can any-body help me in this regard ?

I need to connect two keyboards to one Linux machine running a Qt desktop application.

When I inserted two keyboards in the system, they were working well. But the problem is that they are working as one.

I am developing an application using Qt 4, which contains two text-areas in two different simulatenously opened different dialog boxes. I want to use different keyboards for both text-areas. I mean, I want to use Key-board-1 to input text in TextArea1 and Key-board-2 to input text in TextArea2.

Is it possible ?

Thanks and Regards,
Navneet Kataria
