## 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.

## 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.
