QCustomPlot Discussion and Comments

Hi!

I was wondering if it's possible to resize the QCPLegend when grabbing the side of the Legend.
I used this

this->legend->setSelectableParts(QCPLegend::spLegendBox | QCPLegend::spItems);

then I connected the signals :

        connect(this, SIGNAL(mousePress(QMouseEvent*)), this, SLOT(mousePressSignal(QMouseEvent*)));
        connect(this, SIGNAL(mouseRelease(QMouseEvent*)), this, SLOT(mouseReleaseSignal(QMouseEvent*)));

so i'm keeping the position I pressed :

void Class::mousePressSignal(QMouseEvent *event)
{
    if (this->legend->selectTest(event->pos(), false) > 0)
    {
        if(QCPLegend::SelectablePart::spLegendBox == this->legend->selectedParts())
        {
            _resizingLegend = true;
            QPointF mousePoint((event->pos().x()-this->axisRect()->left())/(double)this->axisRect()->width(),
            (event->pos().y()-this->axisRect()->top())/(double)this->axisRect()->height());
            _resizeLegendOrigin = mousePoint;
            }
        }
}

and in mouseReleaseSignal:

void Class::mouseReleaseSignal(QMouseEvent *event)
    {
        if(_resizingLegend) {
            int xPos =  event->pos().x();
            int yPos =  event->pos().y();
            double difference = -1;
            QPointF mousePoint((xPos-this->axisRect()->left())/(double)this->axisRect()->width(),
                (yPos-this->axisRect()->top())/(double)this->axisRect()->height());
            // shorten it
            if(xPos > _resizeLegendOrigin.x())
                difference = mousePoint.x() - _resizeLegendOrigin.x();
            else // make it bigger
                difference = _resizeLegendOrigin.x() - mousePoint.x();
            QRectF rect = this->axisRect()->insetLayout()->insetRect(0);
            qreal left = rect.x();
            rect.setLeft(left+difference);
            this->axisRect()->insetLayout()->setInsetRect(0, rect);
            _resizingLegend = false;
            this->replot();
        }
    }

But the legend doesn't seem to resize for some reasons or am I missing something?
Thank you!
