详细描述
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)).
参见 QGraphicsDropShadowEffect, QGraphicsBlurEffect, and QGraphicsOpacityEffect.
属性
color : QColor
This property holds the color of the effect.
By default, the color is light blue (QColor(0, 0, 192)).
访问函数:
| 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.
访问函数:
| qreal | strength() const |
| void | setStrength(qreal strength) |
Notifier signal:
| void | strengthChanged(qreal strength) |
成员函数
QGraphicsColorizeEffect::QGraphicsColorizeEffect(QObject *parent = Q_NULLPTR)
Constructs a new QGraphicsColorizeEffect instance. The parent parameter is passed to QGraphicsEffect's constructor.
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.
[virtual protected] void QGraphicsColorizeEffect::draw(QPainter *painter)
重新实现 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.
