The QSGDynamicTexture class serves as a baseclass for dynamically changing textures, such as content that is rendered to FBO's. More...
| Header: | #include <QSGDynamicTexture> |
| CMake: | find_package(Qt6 COMPONENTS Quick REQUIRED) target_link_libraries(mytarget PRIVATE Qt6::Quick) |
| qmake: | QT += quick |
| Inherits: | QSGTexture |
| virtual bool | updateTexture() = 0 |
To update the content of the texture, call updateTexture() explicitly.
Note: All classes with QSG prefix should be used solely on the scene graph's rendering thread. See Scene Graph and Rendering for more information.
[pure virtual] bool QSGDynamicTexture::updateTexture()
Call this function to explicitly update the dynamic texture.
The function returns true if the texture was changed as a resul of the update; otherwise returns false.
Note: This function is typically called from QQuickItem::updatePaintNode() or QSGNode::preprocess(), meaning during the synchronization or the node preprocessing phases of the scenegraph. Calling it at other times is discouraged and can lead to unexpected behavior.
