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.
This property holds the color of the effect.
By default, the color is light blue (QColor(0, 0, 192)).
Функции доступа:
| QColor | color () const |
| void | setColor ( const QColor & c ) |
Уведомляющий сигнал:
| void | colorChanged ( const QColor & color ) |
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.
Функции доступа:
| qreal | strength () const |
| void | setStrength ( qreal strength ) |
Уведомляющий сигнал:
| void | strengthChanged ( qreal strength ) |
Constructs a new QGraphicsColorizeEffect instance. The parent parameter is passed to QGraphicsEffect's constructor.
Destroys the effect.
This signal is emitted whenever the effect's color changes. The color parameter holds the effect's new color.
Reimplemented from QGraphicsEffect::draw().
This signal is emitted whenever setStrength() changes the colorize strength property. strength contains the new strength value of the colorize effect.
