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.
- class PySide6.QtWidgets.QGraphicsBlurEffect([parent=None])#
- Parameters:
parent –
PySide6.QtCore.QObject
Constructs a new QGraphicsBlurEffect
instance. The parent
parameter is passed to QGraphicsEffect
‘s constructor.
Note
Properties can be used directly when from __feature__ import true_property
is used or via accessor functions otherwise.
- property PᅟySide6.QtWidgets.QGraphicsBlurEffect.blurHints: Combination of QGraphicsBlurEffect.BlurHint#
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
.

- property PᅟySide6.QtWidgets.QGraphicsBlurEffect.blurRadius: float#
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.

- PySide6.QtWidgets.QGraphicsBlurEffect.BlurHint#
(inherits enum.Flag
) 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 versions of the source. Do not use this hint if the source is going to be dynamically changing.
