Qt version 4.7.0 & QKeyEvent(camera move)

[Serge]

Hi ALL. Sorry for my english, but i need help with irrlicht and Qt.
Mouse events work excellent :

Code: Select all

void Terrain3D::mouseMoveEvent(QMouseEvent *event)
{
  switch(mousePressedBtn){
  case Qt::LeftButton:{
      if(mousePressed){
        irr::SEvent irrEvent;
        irrEvent.EventType = irr::EET_MOUSE_INPUT_EVENT;
        if(m_IrrDevice){
          irrEvent.MouseInput.Event = irr::EMIE_MOUSE_MOVED;

          irrEvent.MouseInput.X = event->x();
          irrEvent.MouseInput.Y = event->y();
          irrEvent.MouseInput.Wheel = 0.0f;

          m_IrrDevice->postEventFromUser(irrEvent);
        }
        update();
      }
    }
    break;
  default: break;
  }
}

But key event dont'work.
Му class:

Code: Select all

class Terrain3D : public QWidget
{
  Q_OBJECT
public:
  irr::IrrlichtDevice *m_IrrDevice;
  irr::video::E_DRIVER_TYPE m_DriverType;
  irr::video::SColor m_ClearColor;
  ...
  ...
  ...
protected:
  virtual QPaintEngine * paintEngine() const;
  virtual void resizeEvent(QResizeEvent *event);
  virtual void paintEvent(QPaintEvent *event);
  virtual void mousePressEvent(QMouseEvent *event);
  virtual void mouseReleaseEvent(QMouseEvent *event);
  virtual void mouseMoveEvent(QMouseEvent *event);
  virtual void wheelEvent(QWheelEvent *);
  virtual void keyPressEvent(QKeyEvent *event);
  virtual void keyReleaseEvent(QKeyEvent *event);
};

Code: Select all

void Terrain3D::keyPressEvent(QKeyEvent * event)
{
  irr::SEvent::SKeyInput evt;
  evt.Key = irr::KEY_UP;
  irr::SEvent wrapper;
  wrapper.KeyInput = evt;
  wrapper.EventType = EET_KEY_INPUT_EVENT;
  wrapper.KeyInput.PressedDown = true;
  qDebug() << m_IrrDevice->postEventFromUser(wrapper);
  update();
};

m_IrrDevice->postEventFromUser(wrapper) - return TRUE, but camera don't move.

humn... this has been done before, did you search the forums??


Anyways, here you go :
http://irrlicht.sourceforge.net/phpBB2/ ... ichtwidget

This should sort out all your problems.

yes, i read this topic long time ago. but this don't help me.
I will repeat, m_IrrDevice->postEventFromUser(wrapper) return TRUE, event means has left to Irrlicht device, and i can catch event in

Code: Select all

class MyEventReceiver : public IEventReceiver
{
public:
  // keyboard registry
  bool keys[irr::KEY_KEY_CODES_COUNT];

   virtual bool OnEvent(const SEvent& event)
   {
      if(event.EventType == irr::EET_KEY_INPUT_EVENT)
      {
         keys[event.KeyInput.Key] = event.KeyInput.PressedDown;
         qDebug() << event.KeyInput.Key;
         return false;
      }
      return false;
   }
};
void Terrain3DTiled::initialize()
{
  if(m_IrrDevice != 0) // Чтобы не инициализировать дважды
    return;

  // Создаем Irrlicht устойство в первый раз
  irr::SIrrlichtCreationParameters createParams;
  createParams.DriverType = m_DriverType;
  createParams.WindowSize = irr::core::dimension2d<irr::u32>( size().width(), size().height() );
  createParams.Stencilbuffer = true;
  createParams.IgnoreInput = false;
  createParams.Fullscreen = false;

  reciever = new MyEventReceiver;
  createParams.EventReceiver = reciever;

  createParams.WindowId = (void*) winId();

  qDebug() << "   render size           = " << createParams.WindowSize.Width << " x " << createParams.WindowSize.Height;
  qDebug() << "   native window ID      = " << (void*) createParams.WindowId;

  if((m_IrrDevice = irr::createDeviceEx( createParams)) == 0)
      throw( "failed to create Irrlicht device" );
}

But FPS camera don't move.
Rotate camera no problem.

I resolve this problem. Read api: void* irr::SIrrlichtCreationParameters::WindowId and findedd where i mistake.
In Qt(and in others gui probably) we mast paint in recursive, and increase the timer.
My paintEven

Code: Select all

void Terrain3DTiled::paintEvent(QPaintEvent */*event*/)
{
  if(m_IrrDevice == 0)
    return;
  if(isActiveWindow()){
    timer->tick();
    m_IrrDevice->getVideoDriver()->beginScene(true, true, m_ClearColor);
    m_IrrDevice->getSceneManager()->drawAll();
    m_IrrDevice->getGUIEnvironment()->drawAll();
    m_IrrDevice->getVideoDriver()->endScene();
    int fps = m_IrrDevice->getVideoDriver()->getFPS();
    ((QWidget*)parent())->setWindowTitle(QString("FPS: %1").arg(fps));
    update();
  }
}

Now FPS camera move well.
