Graphical Effects | Qt Graphical Effects 5.15.19 (original) (raw)

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 QtGraphicalEffects 1.15

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.
