      Description

      InputPanels defaults z value should be lower than max value, so it is not possible to set a z value for other components which are supposed to be shown over the InputPanel, like bottom bar.
      5000 would be an acceptable value and it should be also documented.

      The problem is here:
      https://code.qt.io/cgit/qt/qtvirtualkeyboard.git/tree/src/virtualkeyboard/qvirtualkeyboardinputcontext_p.cpp?h=5.15.2#n224

      void QVirtualKeyboardInputContextPrivate::registerInputPanel(QObject *inputPanel)
      {
          VIRTUALKEYBOARD_DEBUG() << "QVirtualKeyboardInputContextPrivate::registerInputPanel():" << inputPanel;
          Q_ASSERT(!this->inputPanel);
          this->inputPanel = inputPanel;
          if (QQuickItem *item = qobject_cast<QQuickItem *>(inputPanel))
              item->setZ(std::numeric_limits<qreal>::max());
      }
      

      workaround is to set a timer to set the z value:

      InputPanel {
              id: inputPanel
              Timer
              {
                  repeat: false
                  running: true
                  interval: 60
                  onTriggered: inputPanel.z = 99
              }
      }
