Member Function Documentation
QGraphicsColorizeEffect::QGraphicsColorizeEffect ( QObject * parent = 0 )
Constructs a new QGraphicsColorizeEffect instance. The parent parameter is passed to QGraphicsEffect's constructor.
QGraphicsColorizeEffect::~QGraphicsColorizeEffect ()
Destroys the effect.
void QGraphicsColorizeEffect::colorChanged ( const QColor & color ) [signal]
This signal is emitted whenever the effect's color changes. The color parameter holds the effect's new color.
void QGraphicsColorizeEffect::draw ( QPainter * painter ) [virtual protected]
Reimplemented from QGraphicsEffect::draw().
void QGraphicsColorizeEffect::strengthChanged ( qreal strength ) [signal]
This signal is emitted whenever setStrength() changes the colorize strength property. strength contains the new strength value of the colorize effect.
