Constructor & Destructor Documentation

◆ QQuickMultiEffect()

QT_BEGIN_NAMESPACE QQuickMultiEffect::QQuickMultiEffect ( QQuickItem * parent = nullptr )

\keyword Qt Quick Effects \qmlmodule QtQuick.Effects \title Qt Quick Effects QML Types

Provides QML types for applying one or more simple graphical effects to Qt Quick items.

To use the types in this module, import the module with the following line:

\qml import QtQuick.Effects \endqml

\qmltype MultiEffect \instantiates QQuickMultiEffect \inqmlmodule QtQuick.Effects \inherits Item

Applies post-processing effect to an item.

The MultiEffect type, the successor to the deprecated Qt Graphical Effects from Qt 5, applies a post-processing effect to the \l source item. Compared to the Qt Graphical Effects module, MultiEffect combines multiple effects (blur, shadow, colorization etc.) into a single item and shader which makes it better for multiple effects. There are several shader variations and the most optimal one gets selected based on the features used.

MultiEffect is designed specifically for most common effects and can be easily animated. If the MultiEffect doesn't contain the effect you need, consider implementing a custom effect using \l {Qt Quick Effect Maker}. For more information about shader effects, see the \l ShaderEffect reference documentation.

◆ autoPaddingEnabled()

bool QQuickMultiEffect::autoPaddingEnabled ( ) const

\qmlproperty bool QtQuick.Effects::MultiEffect::autoPaddingEnabled

When blur or shadow effects are enabled and this is set to true (default), the item size is padded automatically based on blurMax and blurMultiplier. Note that \l paddingRect is always added to the size.

◆ blur()

qreal QQuickMultiEffect::blur ( ) const

\qmlproperty real QtQuick.Effects::MultiEffect::blur

This property defines how much blur (radius) is applied to the source.

The value ranges from 0.0 (no blur) to 1.0 (full blur). By default, the property is set to 0.0 (no change). The amount of full blur is affected by blurMax and blurMultiplier.

{Performance note:} If you don't need to go close to 1.0 at any point of blur animations, consider reducing blurMax or blurMultiplier for optimal performance.

\qmlproperty int QtQuick.Effects::MultiEffect::blurMax

This property defines the maximum pixel radius that blur with value 1.0 will reach.

Meaningful range of this value is from 2 (subtle blur) to 64 (high blur). By default, the property is set to 32. For the most optimal performance, select as small value as you need.

Note: This affects to both blur and shadow effects.

This property defines a multiplier for extending the blur radius.

The value ranges from 0.0 (not multiplied) to inf. By default, the property is set to 0.0. Incresing the multiplier extends the blur radius, but decreases the blur quality. This is more performant option for a bigger blur radius than blurMax as it doesn't increase the amount of texture lookups.

When enabling the shadow, you typically need to take \l shadowHorizontalOffset and \l shadowVerticalOffset into account and adjust this paddingRect accordingly.

Below is an example of adjusting paddingRect with autoPaddingEnabled set to false so that the shadow fits inside the MultiEffect item.

\qmlproperty Item QtQuick.Effects::MultiEffect::source

This property holds the item to be used as a source for the effect. If needed, MultiEffect will internally generate a \l ShaderEffectSource as the texture source.

Note: It is not supported to let the effect include itself, for instance by setting source to the effect's parent.; If the source item has \l {QtQuick::Item::layer.enabled} {layer.enabled} set to true, it will be used directly. This is good for the performance and often desired, when the source is hidden. But if the source remains visible and the effect adds padding (autoPaddingEnabled, paddingRect), that padding can affect the appearance of the source item.
