The Qt Quick Ultralite Safe Renderer module provides QML types that are used for safety-critical items in Qt Quick Ultralite applications. It aims to be compatible with Qt Safe Renderer QML Types.

Using the Module

To use the Qt Quick Ultralite Safe Renderer QML types, add Qul::SafeRenderer to the list of module files in your in your .qmlproject.

ModuleFiles {
    MCU.qulModules: ["Qul::SafeRenderer"]
}

After adding the module files, add the following import statement to your .qml file:

import QtQuickUltralite.SafeRenderer

Define APP_SAFE_RENDERER to enable the Safe Renderer Bitmap (SRB) decoder when using a generated entrypoint.

Add the SRB decoder to the image decoders list when using a custom main:

// ...
#include <qul/imagedecoders/saferendererbitmapdecoder.h>

int main()
{
    Qul::initHardware();

    static SafeRendererBitmapDecoder srbDecoder;
    Qul::Application::addImageDecoder(&srbDecoder);

    Qul::initPlatform();
    Qul::Application app;
    // ...

Linking an Application to the CMake Target

When using CMake projects, link your application to the Qul::SafeRenderer CMake target.

target_link_libraries(app PRIVATE Qul::SafeRenderer)
