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) |
