Qt SCXML C++ Classes

• QScxmlExecutableContent: The QScxmlExecutableContent namespace contains various types used to interpret executable content in state machines.

• QScxmlCompiler: The QScxmlCompiler class is a compiler for SCXML files.

• QScxmlCompiler::Loader: The Loader class is a URI resolver and resource loader for an SCXML compiler.

• QScxmlCppDataModel: The QScxmlCppDataModel class is a C++ data model for a Qt SCXML state machine.

• QScxmlDataModel: The QScxmlDataModel class is the data model base class for a Qt SCXML state machine.

• QScxmlDataModel::ForeachLoopBody: The ForeachLoopBody class represents a function to be executed on each iteration of an SCXML foreach loop.

• QScxmlDynamicScxmlServiceFactory: The QScxmlDynamicScxmlServiceFactory class creates SCXML service instances from documents loaded at runtime.

• QScxmlError: The QScxmlError class describes the errors returned by the Qt SCXML state machine when parsing an SCXML file.

• QScxmlEvent: The QScxmlEvent class is an event for a Qt SCXML state machine.

• QScxmlExecutableContent::AssignmentInfo: The AssingmentInfo class represents a data assignment.

• QScxmlExecutableContent::EvaluatorInfo: The EvaluatorInfo class represents a unit of executable content.

• QScxmlExecutableContent::ForeachInfo: The ForeachInfo class represents a foreach construct.

• QScxmlExecutableContent::InvokeInfo: The InvokeInfo class represents a service invocation.

• QScxmlExecutableContent::ParameterInfo: The ParameterInfo class represents a parameter to a service invocation.

• QScxmlInvokableService: The QScxmlInvokableService class is the base class for services called from state machines.

• QScxmlInvokableServiceFactory: The QScxmlInvokableServiceFactory class creates invokable service instances.

• QScxmlNullDataModel: The QScxmlNullDataModel class is the null data model for a Qt SCXML stateMachine.

• QScxmlStateMachine: The QScxmlStateMachine class provides an interface to the state machines created from SCXML files.

• QScxmlStaticScxmlServiceFactory: The QScxmlStaticScxmlServiceFactory class creates SCXML service instances from precompiled documents.

• QScxmlTableData: The QScxmlTableData class is used by compiled state machines.

To use the module with cmake, use the find_package() command to locate the needed module components in the Qt6 package:

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

To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:

QT += scxml
