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

[Navneet Kataria]

How to get xinput2 support in Qt-for-Desktop ?
 
I had seen in http://doc.qt.nokia.com/4.7-snapshot/requirements-x11.html that there is support for X11 Input Extensions. But how to enable/use it for Desktop edition of Qt ?
 
I had checked that this support is enabled for harmattan version; but I want these features for desktop.
 
Can some-body help me in this regard ?
 
Thanks In Advance,
Navneet Kataria

Hello,
 
I got the solution for Linux. Now how to do it using Qt ?
 
Actually I tried xinput as mentioned in the article :->
https://www.linux.com/learn/tutorials/542356-weekend-project-zap-your-coworkers-minds-with-multi-pointer-x
 
I got two pointers for two mouse and two keyboards as master. I opened two terminals and was able to type on both of them using different keyboards.
 
Now the problem is that How to give support of using two different keboards in one Qt application. 
I can use them in two different processes without any problem, but how to use them in one single process ?

Can any-body help ?

Ahh!!
 
May be, I got it !! First I have to distigish the two keyboards, then-only I can proceed to the main problem (if it remains). 
 
Thanks Atlant ! 
I will get back to this thread after trying the above suggestion !

  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
  indistinguishable.

  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
  drivers. 
  
  This page seems to be a nice general reference: 
  
    http://gunnarwrobel.de/wiki/Linux-and-the-keyboard.html 
  
  This page seems to go pretty directly to your question: 
  
    http://linuxgazette.net/124/smith.html 
  
  Together, they may give you some ideas. Once the Linux problem
  is solved, *THEN* it can become a Qt problem.

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 ?
