• QColor color (self)
• draw (self, QPainter painter)
• setColor (self, QColor c)
• setStrength (self, float strength)
• float strength (self)

Qt Signals

• void colorChanged (const QColor&)
• void strengthChanged (qreal)

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)).

Method Documentation

QGraphicsColorizeEffect.__init__ (self, QObject parent = None)

The parent argument, if not None, causes self to be owned by Qt instead of PyQt.

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

QColor QGraphicsColorizeEffect.color (self)

QGraphicsColorizeEffect.draw (self, QPainter painter)

Reimplemented from QGraphicsEffect.draw().

QGraphicsColorizeEffect.setColor (self, QColor c)

This method is also a Qt slot with the C++ signature void setColor(const QColor&).

QGraphicsColorizeEffect.setStrength (self, float strength)

This method is also a Qt slot with the C++ signature void setStrength(qreal).

float QGraphicsColorizeEffect.strength (self)

Qt Signal Documentation

void colorChanged (const QColor&)

This is the default overload of this signal.

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

void strengthChanged (qreal)

This is the default overload of this signal.

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