Detailed Description

The QGraphicsColorizeEffect class provides a colorize effect.

A colorize effect renders the source with a tint of its color(). The color can be modified using the setColor() function.

By default, the color is light blue (QColor(0, 0, 192)).

Property Documentation

color : QColor

This property holds the color of the effect.

By default, the color is light blue (QColor(0, 0, 192)).

Access functions:

QColor	color () const
void	setColor ( const QColor & c )

Notifier signal:

void	colorChanged ( const QColor & color )

strength : qreal

This property holds the strength of the effect.

By default, the strength is 1.0. A strength 0.0 equals to no effect, while 1.0 means full colorization.

Access functions:

qreal	strength () const
void	setStrength ( qreal strength )

Notifier signal:

void	strengthChanged ( qreal strength )

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.
