This signal is emitted at + the start of every frame, before the scene graph starts its + rendering, thus any D3D11 draw calls that are made as a response + to this signal, will stack under the Qt Quick items. + + As an alternative, applications that wish to render D3D11 content + on top of the Qt Quick scene, can do so by connecting to the \l + QQuickWindow::afterRendering() signal. + + In this example, we will also see how it is possible to have + values that are exposed to QML which affect the D3D11 + rendering. We animate the threshold value using a NumberAnimation + in the QML file and this value is used by the HLSL shader + program that draws the squircles. + + The example is equivalent in most ways to the \l{Scene Graph - OpenGL Under + QML}{OpenGL Under QML}, \l{Scene Graph - Metal Under QML}{Metal Under QML}, + and \l{Scene Graph - Vulkan Under QML}{Vulkan Under QML} examples, they all + render the same custom content, just via different native APIs. + + */ |
