Detailed Description

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.

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.

Constant	Description
QGraphicsBlurEffect.PerformanceHint	Indicates that rendering performance is the most important factor, at the potential cost of lower quality.
QGraphicsBlurEffect.QualityHint	Indicates that rendering quality is the most important factor, at the potential cost of lower performance.
QGraphicsBlurEffect.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.
