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)).

See also QGraphicsDropShadowEffect, QGraphicsBlurEffect, and QGraphicsOpacityEffect.

Member Function Documentation

QGraphicsColorizeEffect::QGraphicsColorizeEffect(QObject *parent = nullptr)

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

[virtual] QGraphicsColorizeEffect::~QGraphicsColorizeEffect()

Destroys the effect.

[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.

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

Reimplemented from QGraphicsEffect::draw().

[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.
