svg icons not showing up

[jpn]

Remember to add "QT += svg" to your .pro file..

#include <QSvgRenderer>
 
void SvgToolButton::paintEvent(QPaintEvent* e)
{
	// allow button to paint it's borders..
	QToolButton::paintEvent(e);
	// buffer is a member variable of type QPixmap
	if (buffer.isNull() || buffer.size() != size() - margin)
	{
		// margin is a member variable of type QSize
		buffer = QPixmap(size() - margin);
		QString fileName("button.svg");
		QSvgRenderer renderer(fileName);
		QPainter painter(&buffer);
		renderer.render(&painter);
	}
	// draw a pixmap on the button
	QPainter painter(this);
	painter.drawPixmap(margin.height()/2, margin.width()/2, buffer);
}

#include <QSvgRenderer>

void SvgToolButton::paintEvent(QPaintEvent* e)
{
	// allow button to paint it's borders..
	QToolButton::paintEvent(e);
	// buffer is a member variable of type QPixmap
	if (buffer.isNull() || buffer.size() != size() - margin)
	{
		// margin is a member variable of type QSize
		buffer = QPixmap(size() - margin);
		QString fileName("button.svg");
		QSvgRenderer renderer(fileName);
		QPainter painter(&buffer);
		renderer.render(&painter);
	}
	// draw a pixmap on the button
	QPainter painter(this);
	painter.drawPixmap(margin.height()/2, margin.width()/2, buffer);
}

Edit: Btw, I did not test above code. Oh, and you might want to initialize the svg renderer somewhere else..
