get Tree Item rect on mousePressEvent

[Craetor]

I use QTreeView with model. How can i get Widget or Rect of QTreeView item in his mousePressEvent.

I try

void CSProjectsTreeView::mousePressEvent(QMouseEvent *in_pEvent)
{
    bool l_bDefault = true;
    if(in_pEvent->button() == Qt::LeftButton)
    {
        QPoint l_Pos = in_pEvent->pos();
        QModelIndex l_Index = indexAt(l_Pos);
        CSTreeModel* l_pModel = (CSTreeModel*)((QTreeView*)parent())->model();
        CSTreeItem* l_pItem = l_pModel->getItem(l_Index);

        if(l_pItem->getType() == PROJECT_TREE_ITEM_PROJECT)
        {
            QPixmap pix(":/Images/Resources/Delete.ico");
            QSize size = pix.size();

            QWidget* l_pWidget = indexWidget(l_Index);
            if(l_pWidget)
            {
                QRect l_Rec = l_pWidget->rect();

                int shift = (l_Rec.height() - size.height()) / 2;
                int startX = l_Rec.x() + l_Rec.width() - size.width() - shift;
                int startY = l_Rec.y() + shift;
                int endX = startX + size.width();
                int endY = startY + size.height();

                QRect l_Image(startX, startY, size.width(), size.height());
                if(l_Image.contains(l_Pos))
                {
                    l_bDefault = false;
                    qDebug() << "contain!!!";
                }
            }
        }
    }

    if(l_bDefault)
        QTreeView::mousePressEvent(in_pEvent);
}

but it return null anyway.

Any solutions?

@Craetor said in get Tree Item rect on mousePressEvent:

indexWidget

Hi, unless you have set a Widget there it is NULL.
You can use
QRect QAbstractItemView::visualRect(const QModelIndex & index) const

If you need to paint a pixmap over a cell, maybe considering using a delegate ?

@mrjj, it works great, thanks!

Yes, i draw an image on paint event by the QStyledItemDelegate and detect his rect on mousePressEvent
