* RectangularShadow: Remove note about individual corner radiusKaj Grönholm2025-11-051-4/+3
| | | | | | | | Since Qt 6.11, individual corner radius are supported. Task-number: QTBUG-141110 Change-Id: I38382ff4c20e53ea1f380ac6ae103ddf0cf527e6 Reviewed-by: Richard Moe Gustavsen <richard.gustavsen@qt.io>
* RectangularShadow: Add support for individual corner radiusKaj Grönholm2025-10-235-11/+365
| | | | | | | | | | | | Add API for specifying individual corner radius values similar to Quick Rectangle. Try to keep the overhead minimum when not used, by storing data in lazily allocated extra and using separate shader. Use the API in the neumorphicpanel example.

* Add RectangularShadow elementKaj Grönholm2024-11-096-0/+792
| | | | | | | | | | | | | | | | | | | | | | | | Add a new element into QtQuick.Effects called RectangularShadow. This is a high performance shadow/glow for (rounded)rectangle shapes. Differences compared to QGE RectangularGlow: - Implemented in C++ and part of QtQuick.Effects module. - Different API, modelled based on CSS box-shadow. - Shader uses SDFs math for rounded rectangle. Reduced item size and properly rounding math (circle is a circle). - Allows offset and spread relative to item. - Default color is black (shadow) rather than white (glow). - Using "layer.enabled" for cache property rather than separate ShaderEffectSource. - Property "material" so shader effect can be customized. QQEM can contain RectangularShadow node for easier customization. Contains an example and lancelot tests.

* Fix conflicting QGfxSourceProxy meta object with the one in qt5compatAlexandru Croitor2024-10-184-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | There are two QGfxSourceProxy classes in the codebase, one in qt5compat/src/imports/graphicaleffects5/private and the other in qtdeclarative/src/effects. In a static build, if a project links and initializes both qml modules, it is undetermined which QGfxSourceProxy class' meta object will be loaded. This can lead to the multi effects object version being loaded when initializing a component from the graphical effects module. You then get a warning message saying "Missing QML.Element class info for QGfxSourceProxy" and then a failure to load the QML module. This happened for the sample qmake project attached to the bug report this change is fixing. Rename the multi effects QGfxSourceProxy class to QGfxSourceProxyME (where ME stands for Multi Effects) to avoid the meta object conflict.

Add new QtQuick.Effects plugin for post-processing effects. The plan is to add essential effects directly into QtQuick, not to duplicate Qt Graphical Effects. Initially the plugin will contain MultiEffect which supports 7 different effects in a single ShaderEffect (brightness, contrast, saturation, colorize, blur, shadow, mask). Combining multiple effects into a single shader is more performant than chaining multiple effect items. Depending on used features, the most optimal shader gets selected. Includes two examples demonstrating the usage of MultiEffect.
