Qt Quick Ultralite provides compatibility modules to let you use Qt Quick Ultralite QML objects with Qt QML. The modules are located in
Qul_DIR/compatibility
.
Qt Quick Ultralite offers the following compatibility modules:
Name | Minimum version |
---|---|
Extras | 1.0 |
Layers | 1.7 |
注意: Every module can be imported with the minor version number of the currently installed package.
To use any of the modules one must add the
Qul_DIR/compatibility
directory to the
QML import path
and import the desired module in the
.qml
文件:
注意:
The modules require
Qt 5.15
.
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_DIR/compatibility"); ... return app.exec(); }
// sample main.qml file import QtQuick 2.15 ... import QtQuickUltralite.Extras 1.7 Window { ... StaticText { text: "Hello World!" } }
注意:
Extras
module uses C++ and therefore the module's binaries must match with the user's project configuration.
To take advantage of Qt Creator's code completion, append the
Qul_DIR/compatibility
directory to the
QML_IMPORT_PATH
.
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 https://cmake.org/cmake/help/latest/command/add_subdirectory.html of the
CMakeLists.txt
:
set(QUL_COMPATIBILITY_DIR ${Qul_DIR}/compatibility) add_subdirectory(${QUL_COMPATIBILITY_DIR} ${CMAKE_BINARY_DIR}/compatibility)
Then add a dependency to your target:
add_dependencies(my_target QtQuickUltraliteExtras)
