How I can use a "Mouse Leave" event inside QItemDelegate::editorEvent ?

[rsilva]

I'm using this code, but the editorEvent doesn't called in a "leave" event.
And the mouse move don't capture events outside the item rect

bool DownloadItemDelegate::editorEvent(
    QEvent* event,
    QAbstractItemModel* model,
    const QStyleOptionViewItem& option,
    const QModelIndex &index)
{
    if (event->type() == QEvent::MouseButtonPress)
    {
        QMouseEvent* e = (QMouseEvent*)event;
 
        if (index.data(Qt::UserRole).toRect().contains(e->pos())) // button "resume"
        {
            model->setData(index, true, Qt::UserRole + 1); // button pressed (visual-only | button style = sunken)
            model->setData(index, true, Qt::UserRole + 2); // button pressed (is clicked?)
            return true;
        }
    }
    else if (event->type() == QEvent::MouseButtonRelease)
    {
        QMouseEvent* e = (QMouseEvent*)event;
 
        if (index.data(Qt::UserRole).toRect().contains(e->pos()))
        {
            model->setData(index, false, Qt::UserRole + 1); // button style = enabled
 
            if (index.data(Qt::UserRole + 2).toBool()) // is clicked == true | emit resume();
            {
                //emit resume_pressed;
            }
 
            return true;
        }
 
        model->setData(index, false, Qt::UserRole + 2); // clear this flag
    }
    else if (event->type() == QEvent::MouseMove)
    {
        QMouseEvent* e = (QMouseEvent*)event;
 
        if (!index.data(Qt::UserRole).toRect().contains(e->pos())) // if exit button rect, button style = enabled
        {
            model->setData(index, false, Qt::UserRole + 1);
            return true;
        }
        else if (index.data(Qt::UserRole + 2).toBool()) // if enter button rect, and, the checked flag is true, button style = sunken
        {
            model->setData(index, true, Qt::UserRole + 1);
            return true;
        }
    }
 
    return false;
}

bool DownloadItemDelegate::editorEvent(
    QEvent* event,
    QAbstractItemModel* model,
    const QStyleOptionViewItem& option,
    const QModelIndex &index)
{
    if (event->type() == QEvent::MouseButtonPress)
    {
        QMouseEvent* e = (QMouseEvent*)event;

        if (index.data(Qt::UserRole).toRect().contains(e->pos())) // button "resume"
        {
            model->setData(index, true, Qt::UserRole + 1); // button pressed (visual-only | button style = sunken)
            model->setData(index, true, Qt::UserRole + 2); // button pressed (is clicked?)
            return true;
        }
    }
    else if (event->type() == QEvent::MouseButtonRelease)
    {
        QMouseEvent* e = (QMouseEvent*)event;

        if (index.data(Qt::UserRole).toRect().contains(e->pos()))
        {
            model->setData(index, false, Qt::UserRole + 1); // button style = enabled

            if (index.data(Qt::UserRole + 2).toBool()) // is clicked == true | emit resume();
            {
                //emit resume_pressed;
            }

            return true;
        }

        model->setData(index, false, Qt::UserRole + 2); // clear this flag
    }
    else if (event->type() == QEvent::MouseMove)
    {
        QMouseEvent* e = (QMouseEvent*)event;

        if (!index.data(Qt::UserRole).toRect().contains(e->pos())) // if exit button rect, button style = enabled
        {
            model->setData(index, false, Qt::UserRole + 1);
            return true;
        }
        else if (index.data(Qt::UserRole + 2).toBool()) // if enter button rect, and, the checked flag is true, button style = sunken
        {
            model->setData(index, true, Qt::UserRole + 1);
            return true;
        }
    }

    return false;
}

This handles the basics of a QPushButton that I need, but, how can I check if the mouse leave the item region ?
I need to check this event to clear the flags of the button.

You will not catch a leaveEvent this way as the cursor is not over the item anymore so a different item will start receiving events. That's your clue that the cursor has left the item.

So, the solution is to remove the pressed flag from the event function of all other widgets, when they get an event? Does not seem right.

with the MouseOver option flag like described here it works: http://www.qtcentre.org/threads/1314...te-enter-event
