How to resize and make the new size persistent in QSvgWidget?

[deleted385]

It's a continuation of this post. With that approach when I resize the pixmap, it gets pixelated so I've converted that into a QSvgWidget like this:

ActionButton::ActionButton(const QString &fileName, QWidget *parent) : QSvgWidget(parent){
    QFile f(fileName);
    f.open(QIODevice::ReadOnly | QIODevice::Text);
    m_document.setContent(f.readAll()); //QDomDocument m_document;
    changeColor(Qt::black);
}
void ActionButton::enterEvent(QEnterEvent*){ changeColor(Qt::blue); }
void ActionButton::leaveEvent(QEvent*){ changeColor(Qt::black);}
void ActionButton::mousePressEvent(QMouseEvent*){ changeColor(Qt::red); }
void ActionButton::mouseReleaseEvent(QMouseEvent*){ emit triggered(); }
void ActionButton::changeColor(const QColor &color){
    m_document.elementsByTagName("path").at(0).toElement().setAttribute("fill", color.name());
    resize(QSize(14, 14));
    renderer()->load(m_document.toByteArray());
}

and this is what I get with those;

initially, those icons were not resized although I've a changeColor(Qt::black) call in the constructor. Later when I hover over those icons, they're resized. How to get those resized when they're displayed/rendered first? Is it possible to make the new size persistent and avoid resize(QSize(14, 14)) call in changeColor function?

@Emon-Haque, took a while to figure out that setMaximumSize(QSize(14, 14)) is what I need in the constructor!
