QWebView and right click reload

[sky]

Hi Squidge,

Thank you for your suggestion. I implemented it and below is the code. But I was not able to get it to disable the right click on flash videos. And also I ran it through the debugger with a break point in the eventFilter method. And it looks like this eventFilter is never being called.

It looks like as if the events in QT are broadcasted to all the QObjects in the application. Also please do let me know if you know of any good literature that explains qt event mechanism in detail. Thank you.

    : QWebView(parent),  m_page(this), m_pXMLHttp(NULL)
{
 
    installEventFilter(this);
 
    setPage(&m_page);
    m_pFrame = page()->mainFrame();
 
    m_page.installEventFilter(this);
    m_pFrame->installEventFilter(this);
}
 
bool Browser::eventFilter(QObject *obj, QEvent *event)
{
   if ( (event->type() == QEvent::MouseButtonPress  )||
        (event->type() == QEvent::MouseButtonRelease)||
        ( event->type() == QEvent::MouseButtonDblClick  ) )
    {
        QMouseEvent *mouseEvent = static_cast<QMouseEvent *>(event);
        if (mouseEvent->button() == Qt::RightButton)
        {
            mouseEvent->accept();
            return true;
        }

    //return QWebView::eventFilter(obj, event);
   return false;

The best way if you want just to remove the "Reload" option from standart web view context menu is to use the following:

myWebView->page()->action(QWebPage::Reload)->setVisible(false);

(myWebView type is QWebView*)

If you want to hide any other standart context menu items just look at enum QWebPage::WebAction members

Hope this helps.

I just got into the same problem but I also want to make the right click menu dynamically available. I still want to enable the right click menu just for debug purpose. In my case, calling setContextMenuPolicy() was a little awkward so I decided to give installEventFilter() one more try:

bool MyObject::eventFilter( QObject *watched, QEvent *event )
{
    if( NULL != event )
    {
        QEvent::Type type = event->type();
        if( ! m_bMouseEnabled &&
                ( type==QEvent::MouseButtonDblClick ||
                  type==QEvent::MouseButtonPress ||
                  type==QEvent::MouseButtonRelease ||
                  type==QEvent::MouseMove ||
                  type==QEvent::MouseTrackingChange ||
                  type==QEvent::ContextMenu ||
                  type==QEvent::GraphicsSceneContextMenu )
          )
        {
            return true;
        }
    }
    return false;
}
 
void WebKitView::initialize()
{
    m_webView->installEventFilter( m_myObj );
}

bool MyObject::eventFilter( QObject *watched, QEvent *event )
{
    if( NULL != event )
    {
        QEvent::Type type = event->type();
        if( ! m_bMouseEnabled &&
                ( type==QEvent::MouseButtonDblClick ||
                  type==QEvent::MouseButtonPress ||
                  type==QEvent::MouseButtonRelease ||
                  type==QEvent::MouseMove ||
                  type==QEvent::MouseTrackingChange ||
                  type==QEvent::ContextMenu ||
                  type==QEvent::GraphicsSceneContextMenu )
          )
        {
            return true;
        }
    }
    return false;
}

void WebKitView::initialize()
{
    m_webView->installEventFilter( m_myObj );
}

Adding the checking of QEvent::ContextMenu and QEvent::GraphicsSceneContextMenu made it work in my application. I am not sure if this works for flash, tough.

In a talk by one of the google developers of chromium - about the architecture of chromium,
he said that flash talks directly to the OS behind the scenes. It acquires its own HWND etc,
so flash probably gets the right-click directly from the OS, bypassing Qt.
