Qt 5 Compatibility APIs: Qt Graphical Effects

The Qt Graphical Effects module is provided for compatibility with applications written for Qt 5. As far as practically feasible, effects have been ported, but some dynamically generated effects are incompatible with the approach to shader effects in Qt 6 and have thus been left out:

• Blend
• InnerShadow
• All blur effects besides FastBlur: GaussianBlur, MaskedBlur, RecursiveBlur, DirectionalBlur, RadialBlur, ZoomBlur.

Dependencies on any of these types have to be replaced by a custom shader effect in the application code.

Effects are visual items that can be added to Qt Quick user interface as UI components. To import the Qt Graphical Effects types, include the Qt Graphical Effects module by adding the following statement to the QML file:

import Qt5Compat.GraphicalEffects

To use the effects, simply add a specific effect declaration to the QML scene and configure the effects properties. The source item type can be any QML type, even video or another effect. Pipelining multiple effects together is a simple way to create even more impressive output.

The following list presents the functional division of types that are part of Qt Graphical Effects:

Color

Gradient

Distortion

Drop Shadow

Blur

Glow

Mask
