Qt Quick Ultralite's Qt QML compatibility modules

Qt Quick Ultralite provides compatibility modules to let you use Qt Quick Ultralite QML objects with Qt QML. The modules are located in <Qul install directory>/compatibility.

Qt Quick Ultralite offers the following compatibility modules:

To use any of the modules one must add the <Qul install directory>/compatibility directory to the QML import path and import the desired module in the .qml file:

Import the Qt Quick Ultralite Extras and Qt Quick Ultralite Layers modules.

// sample main.cpp file
...

int main(int argc, char *argv[])
{
    ...

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    engine.addImportPath("<Qul install directory>/compatibility");

    ...

    return app.exec();
}

// sample main.qml file
import QtQuick 2.15
...
import QtQuickUltralite.Extras 2.5.4

Window {
    ...

    StaticText {
        text: "Hello World!"
    }
}

To take advantage of Qt Creator's code completion, append the <Qul install directory>/compatibility directory to the QML_IMPORT_PATH.

Building

The Qt Quick Ultralite source package provides sources for the modules, which are located in QUL_DIR/compatibility/QtQuickUltralite/* If the provided binaries don't match your project configuration, you can build the library with the desired settings.

The package contains a CMakeLists.txt file that builds the modules. To build the Extras module execute the QtQuickUltraliteExtras CMake target. The default output location is set to the CMAKE_BINARY_DIR CMake variable and can be changed by setting the QUL_COMPATIBILITY_MODULE_DIR CMake variable.

To automate the process you can add_subdirectory of the CMakeLists.txt:

set(QUL_COMPATIBILITY_DIR ${<Qul install directory>}/compatibility)
add_subdirectory(${QUL_COMPATIBILITY_DIR} ${CMAKE_BINARY_DIR}/compatibility)

Then add a dependency to your target:

add_dependencies(my_target QtQuickUltraliteExtras)
