      m_brush(painter->brush())
{
}

KisPaintingTweaks::PenBrushSaver::PenBrushSaver	(	QPainter *	painter,
		const QPen &	pen,
		const QBrush &	brush )

Overrides pen and brush of painter with the provided values. painter cannot be null.

PenBrushSaver() [3/5]

KisPaintingTweaks::PenBrushSaver::PenBrushSaver	(	QPainter *	painter,
		const QPair< QPen, QBrush > &	pair )

Overrides pen and brush of painter with the provided values. painter cannot be null.

Definition at line 71 of file kis_painting_tweaks.cpp.

    : PenBrushSaver(painter)
{
    m_painter->setPen(pair.first);
    m_painter->setBrush(pair.second);
}

PenBrushSaver() [4/5]

KisPaintingTweaks::PenBrushSaver::PenBrushSaver	(	QPainter *	painter,
		const QPair< QPen, QBrush > &	pair,
		allow_noop_t	)

A special constructor of PenBrushSaver that allows painter to be null. Passing null pointer will basically mean that the whole saver existence will be a noop.

Definition at line 78 of file kis_painting_tweaks.cpp.

    : m_painter(painter)
{
    if (m_painter) {
        m_pen = m_painter->pen();
        m_brush = m_painter->brush();
        m_painter->setPen(pair.first);
        m_painter->setBrush(pair.second);
    }
}
