Detailed Description

The QGraphicsBlurEffect class provides a blur effect.

A blur effect blurs the source. This effect is useful for reducing details, such as when the source loses focus and you want to draw attention to other elements. The level of detail can be modified using the setBlurRadius() function. Use setBlurHints() to choose the blur hints.

By default, the blur radius is 5 pixels. The blur radius is specified in device coordinates.

See also QGraphicsDropShadowEffect, QGraphicsColorizeEffect, and QGraphicsOpacityEffect.

Member Enumeration Documentation

enum QtGui.QGraphicsBlurEffect.BlurHint

This enum describes the possible hints that can be used to control how blur effects are applied. The hints might not have an effect in all the paint engines.

This enum was introduced or modified in Qt 4.6.

See also blurHints() and setBlurHints().

Enumerator:

AnimationHint	Indicates that the blur radius is going to be animated, hinting that the implementation can keep a cache of blurred verisons of the source. Do not use this hint if the source is going to be dynamically changing.
PerformanceHint	Indicates that rendering performance is the most important factor, at the potential cost of lower quality.
QualityHint	Indicates that rendering quality is the most important factor, at the potential cost of lower performance.

Property Documentation

new BlurHint QtGui.QGraphicsBlurEffect.BlurHints

getset

This property holds the blur hint of the effect.

Use the PerformanceHint hint to say that you want a faster blur, the QualityHint hint to say that you prefer a higher quality blur, or the AnimationHint when you want to animate the blur radius.

By default, the blur hint is PerformanceHint.

Slot<QGraphicsBlurEffect.BlurHint> QtGui.QGraphicsBlurEffect.BlurHintsChanged

addremove

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

new double QtGui.QGraphicsBlurEffect.BlurRadius

getset

This property holds the blur radius of the effect.

Using a smaller radius results in a sharper appearance, whereas a bigger radius results in a more blurred appearance.

By default, the blur radius is 5 pixels.

The radius is given in device coordinates, meaning it is unaffected by scale.

Slot<System.Double> QtGui.QGraphicsBlurEffect.BlurRadiusChanged

addremove

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