Qt State Machine

The State Machine framework provides classes for creating and executing state graphs.

使用模块

QML API

The QML types of the module are available through the QtQml.StateMachine 导入。要使用类型，添加以下 import 语句到 .qml 文件：

import QtQml.StateMachine

C++ API

Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake .

构建采用 CMake

使用 find_package() command to locate the needed module component in the Qt6 包：

find_package(Qt6 REQUIRED COMPONENTS StateMachine)
target_link_libraries(mytarget PRIVATE Qt6::StateMachine)

更多细节，见构建采用 CMake 概述。

采用 qmake 构建

使用 find_package() command to locate the needed module component in the Qt6 包：

find_package(Qt6 REQUIRED COMPONENTS statemachine)
target_link_libraries(mytarget PRIVATE Qt6::statemachine)

更多细节，见构建采用 CMake 概述。
