Qt State Machine▲
The State Machine framework provides classes for creating and executing state graphs.
Using the Module▲
QML API▲
The QML types of the module are available through the QtQml.StateMachine import. To use the types, add the following import statement to your .qml file:
import QtQml.StateMachineC++ 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.
Building with CMake▲
Use the find_package() command to locate the needed module component in the Qt6 package:
find_package(Qt6 REQUIRED COMPONENTS StateMachine)
target_link_libraries(mytarget PRIVATE Qt6::StateMachine)For more details, see the Build with CMake overview.
Building with qmake▲
Use the find_package() command to locate the needed module component in the Qt6 package:
find_package(Qt6 REQUIRED COMPONENTS statemachine)
target_link_libraries(mytarget PRIVATE Qt6::statemachine)For more details, see the Build with CMake overview.
