how to override the mouse release event with linkclicked signal?

[ejoshva]

I have a situation here where I need to click on a link to navigate to another page . Something like Table of contents where in when you click on a line it takes you to the respective page. This is done using linkClicked() signal. It was working fine until I wrote a mousePressesEvent() and mouseReleaseEvent() for another requirement.

Now that the linkClicked() signal is superseded by the mouseEvent.

Kindly let me know how to make both work paralleling as I need both linkclick() signal incase of click on a link and mousePressEvent/mouseReleaseEvent in case of selecting the line.

Thankx

I have written something like this. What I am trying to do here is on click and drag and release will show a highlight color options. Only on click , if HREF have to navigate to the respective page.

void webview::mouseReleaseEvent(QGraphicsSceneMouseEvent *event)
{
    qDebug()<<"mouseMove : "<<mouseMove;
    if(mouseMove)
    {
        if(!page()->selectedText().isEmpty())
        {
            QMenu contextMenu;
            p = event->screenPos();
            QAction *highlightsAction = contextMenu.addAction("Highlights");
            highlightsAction->setIcon(QIcon(":/images/highlightbox.png"));
            QAction *notesAction = contextMenu.addAction("Annotaions");
            notesAction->setIcon(QIcon(":/images/notesmenu.png"));
            connect(notesAction, SIGNAL(triggered()), this, SLOT(createannotations()));
            connect(highlightsAction, SIGNAL(triggered()), this, SLOT(createhighlight()));
            QAction *selectedAction = contextMenu.exec(p);
        }
        mouseMove = false;
    }
    else
    {
        qDebug()<<"I am gonna Emit";
        connect(this->page(), SIGNAL(linkClicked(const QUrl&)), this, SLOT(gotoLink(QUrl)));
        //emit linkClicked(url());
    }
 
}
void webview::mouseMoveEvent(QGraphicsSceneMouseEvent *event)
{
    mouseMove = true;
}

void webview::mouseReleaseEvent(QGraphicsSceneMouseEvent *event)
{
    qDebug()<<"mouseMove : "<<mouseMove;
    if(mouseMove)
    {
        if(!page()->selectedText().isEmpty())
        {
            QMenu contextMenu;
            p = event->screenPos();
            QAction *highlightsAction = contextMenu.addAction("Highlights");
            highlightsAction->setIcon(QIcon(":/images/highlightbox.png"));
            QAction *notesAction = contextMenu.addAction("Annotaions");
            notesAction->setIcon(QIcon(":/images/notesmenu.png"));
            connect(notesAction, SIGNAL(triggered()), this, SLOT(createannotations()));
            connect(highlightsAction, SIGNAL(triggered()), this, SLOT(createhighlight()));
            QAction *selectedAction = contextMenu.exec(p);
        }
        mouseMove = false;
    }
    else
    {
        qDebug()<<"I am gonna Emit";
        connect(this->page(), SIGNAL(linkClicked(const QUrl&)), this, SLOT(gotoLink(QUrl)));
        //emit linkClicked(url());
    }

}
void webview::mouseMoveEvent(QGraphicsSceneMouseEvent *event)
{
    mouseMove = true;
}

To copy to clipboard, switch view to plain text mode 

I am unable to emit the signal for the href .

In case of emitting the signal, I want to pass the url, if the point on which the click happened is href.

Call the mouseReleaseEvent and mouseMoveEvent of the baseclass, then it should work again

i don't know what the used base class is, but im presuming that it is a QGraphicsScene
QGraphicsScene::mouseReleaseEvent(event)

As per your suggestion , have modified the code as below. but still in vain to emit the linkclicked signal

void webview::mousePressEvent(QGraphicsSceneMouseEvent *event)
{
mouseDown = true;
p = event->pos().toPoint();
qDebug()<<p;

QWebHitTestResult hit = page()->mainFrame()->hitTestContent(p);
if (hit.isContentEditable())
{

}
QGraphicsWebView::mousePressEvent(event);
}

void webview::mouseReleaseEvent(QGraphicsSceneMouseEven t *event)
{
if(mouseDown == true && p != event->pos().toPoint())
{
qDebug()<<page()->selectedText();
if(!page()->selectedText().isEmpty())
{
QMenu contextMenu;
p = event->screenPos();
QAction *highlightsAction = contextMenu.addAction("Highlights");
highlightsAction->setIcon(QIcon(":/images/highlightbox.png"));
QAction *notesAction = contextMenu.addAction("Annotaions");
notesAction->setIcon(QIcon(":/images/notesmenu.png"));
connect(notesAction, SIGNAL(triggered()), this, SLOT(createannotations()));
connect(highlightsAction, SIGNAL(triggered()), this, SLOT(createhighlight()));
QAction *selectedAction = contextMenu.exec(p);
}
mouseDown = false;
}
else
{

qDebug()<<"I am gonna Emit";
connect(this->page(), SIGNAL(linkClicked(const QUrl&)), this, SLOT(gotoLink(QUrl)));
//emit linkClicked(url());

}
QGraphicsWebView::mouseReleaseEvent(event);
}

Thanks. I works now by calling the event with the baseclass just as u suggested.
