Qt Quick Ultralite QML 类型

The Qt Quick Ultralite module provides graphical primitive types. These types are only available in a QML document if that document imports the QtQuick 名称空间。

To use the QtQuick QML types, link your application to the Qul::QuickUltralite CMake target:

target_link_libraries(app Qul::QuickUltralite Qul::QuickUltralitePlatform)

And add the following import statement to your .qml 文件：

import QtQuick 2.15

For information about QML applications in general, see the Qt documentation on QML 应用程序和 QML 参考 .

Since version 1.3, the QtQuick module offered by Qt Quick Ultralite is source-compatible with Qt's QtQuick module.

子模块

Qt Quick Ultralite has submodules that offer additional types.

Controls - 提供一组可重用 UI 组件
Charts - provides components for creating charts

基本类型

There are a number of basic types that are supported by default in the QML language .

此外， QtQuick import provides the following basic types:

color

ARGB color value
