Detailed Description

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* = nullptr)

Constructs a new QGraphicsColorizeEffect instance. The parent parameter is passed to QGraphicsEffect's constructor.

`[signal]` void QGraphicsColorizeEffect::colorChanged(const QColor &color)

This signal is emitted whenever the effect's color changes. The color parameter holds the effect's new color.

Note: Notifier signal for property color.

`[signal]` void QGraphicsColorizeEffect::strengthChanged(qreal strength)

This signal is emitted whenever setStrength() changes the colorize strength property. strength contains the new strength value of the colorize effect.

Note: Notifier signal for property strength.

`[virtual]` QGraphicsColorizeEffect::~QGraphicsColorizeEffect()

Destroys the effect.

`[override virtual protected]` void QGraphicsColorizeEffect::draw(QPainter **painter*)

Reimplements: QGraphicsEffect::draw(QPainter *painter).
