[Qt-interest] blocked keyevents in embedded linux using qt.

[slheitz at rockwellcollins.com]

I have written a keyboarddriver plugin.

I have am using Qsocketnotifier to signal me when the keyboard character 
device has been updated.

keypadhandler 
{
   KeypadFD = open("/dev/mydevice", O_RDONLY | O_NONBLOCK, 0);

      Notify = new QSocketNotifier(KeypadFD, QSocketNotifier::Read, this);
      connect(Notify, SIGNAL(activated(int)), this, 
SLOT(ReadKeypadData()));

}



  Then my readdata file runs off of the qsockettnotifiersignal.

ReadKeypadData
{
   uint n = read(KeypadFD, KeyPress1, sizeof(KeyPress1));


   then I determine what key it is and translate it to a Qt key event and 
call process keyevent.

   processKeyEvent(EXTENDED_UNICODE, qtkey, Qt::NoModifier, true, false);
 
}



My issue is that when I hit a key the first time it runs through the 
readdata function and I see that it executes and runs processkeyevent. But 
no key event shows up in my running server app.  Then when I hit the key 
agian I see that it 
runs through the readdata function and I see that it processes the 
previous key and the current one.  So the first key is always getting held 
up until I hit another key then it gets sent along with the second key.

Any Ideas?

Thanks

Sean
