    I come from China,
    use English keyboard.
    I think not use any special locale.

    just the key "s" has problem, All other keys are normal.

      Let me summarize the problem:
      1 wince system virtual keyboard no problem;
      2 physical keyboard is normal when use in wince system
      For example, I create a folder and then change the name of the folder,
      3 The s key has the same function as BackSpace key
      4 If I press and hold the s button, can enter the s character normally

      only The s key has this problem

        @CraigTao Is the keyboard maybe broken?
        Did you configure the correct keyboard layout?

          I replaced keyboard, the problem still exists.

          I don't configure keyboard layout. only the s key.

          and

          "2 physical keyboard is normal when use in wince system
          For example, I create a folder and then change the name of the folder,"

          so. I think maybe Qt internal problem?

          which part of Qt source code is handle system key message?

            As I already suggested, first test with Qt 4.8.7.

              When I debugged, I found something interesting

              Inherit from class QLineEdit to implement a LineEdit

              void LineEdit::keyPressEvent( QKeyEvent* pEvent )
              {
              int val = pEvent->key();
              QString = pEvent->text();
              QLineEdit::keyPressEvent(pEvent);
              }

              key s character is ‘s' , but the key value is same as BackSpace : 16777219

                What locale are you using ?
                And again, please test against the latest version of the Qt 4 series.

                  @SGaist thank you so much.
                  I can't update Qt version to 4.8.

                  Now use a method to solve this problem.

                  bool VirtualRunQt::eventFilter( QObject* pObject, QEvent* pEvent )
                  {
                  	if (pEvent->type() == QEvent::KeyPress) {
                  		QKeyEvent *ke = static_cast<QKeyEvent*>(pEvent);
                  		if (ke->text() == "s" && ke->key() == 16777219) {
                  			QKeyEventHelp* pKey = reinterpret_cast<QKeyEventHelp*>(ke);
                  			pKey->k = 83;
                  		}
                  	}
                  	return QObject::eventFilter(pObject, pEvent);
                  }
                  
                  qApp->installEventFilter(this);
                  

                  but I still think this is a bug in Qt4.73

                    @CraigTao said in wince6.0 Qt4.7 Keyboard key error:

                    I can't update Qt version to 4.8

                    It's just to test whether it is an issue with older Qt version you're using.

                      I will test when I am free, now so busy.

                      How do I set the post to be resolved?
