Creating SCXML charts

Creating a unit

Unit is a single scxml chart. It is mostly used for simple charts without invokable sessions.

Select File->New Unit or press Shift+Ctrl+N

new_unit

Creating a project

Project is the most preferred choice of designing scxml charts to get all benefits (custom triggers, nested scxml charts, etc.)

Select File->New Project or press Ctrl+N

new_project

Editing SCXML charts

ScxmlEditor provides a project wizard for opening scxml. It supports either opening files with metainformation about the position of states and transitions or plain scxml files. You can use ScxmlEditor to add states and transitions to the chart. You can add executable content to a state chart to enable the state machine to modify its data model and to interact with external entities.

  1. Select File->Open Unit or press Shift+Ctrl+O (for all types of .scxml files)
  2. Select File->Open Project or press Ctrl+O (for ScxmlEditor .sproj files)

Is used to edit and examine the properties of the currently selected states, executable contents and transitions.

Editor tabs

Are used to add scxml elements, zoom, align, change chart visual options, etc.

Press 'Ctrl+.' to call IDE Insight dialog where you may search for all actions through the application. Add shapes, edit properties in one place!

Structure View with quick search

StructureViewSearch

ScxmlEditor has an ability to receive and send string UDP commands:

Receive API:

  • @@@ - clear highlighted states in all statecharts
  • @@@ScxmlName - clear highlighted states in statechart where <scxml> 'name' is equal ScxmlName
  • Type@ScxmlName@Msg@Id - commands to highlight state or display message in CallStack panel
    Description: Type - integer type of command: 1 - AfterEnter, 2 - BeforeEnter, 3 - AfterExit, 4 - BeforeExit, 5 - Step, 6 - BeforeExecContent, 7 - AfterExecContent, 8 - BeforeInvoke, 9 - AfterInvoke, 10 - BeforeUnInvoke, 11 - AfterUnInvoke, 12 - BeforeTakingTransition, 13 - AfterTakingTransition, 14 - StableConfiguration, 15 - BeforeProcessingEvent
    ScxmlName - name of <scxml>
    Msg - message which depends on type of command. For example: for BeforeEnter or BeforeExit - it is the id(name) of states, for BeforeInvoke or BeforeUnInvoke it is the name of invoked element, etc.
    Id - identifier of the invoked state machine (Since ScxmlEditor 2.2). Can be empty for root machines

BeforeEnter graphically highlight and BeforeExit unhighlight the corresponding states, other commands are displayed in CallStack panel

Since ScxmlEditor 2.3 there is an option to highlight taking transitions in BeforeTakingTransition Message format: FromState|TransitionIndex where TransitionIndex is transition xml child index

Example of commands:

  • 2@CalculatorStateMachine@operand1 - highlight state operand1 in statechart CalculatorStateMachine
  • 4@CalculatorStateMachine@operand1 - unhighlight state operand1 in statechart CalculatorStateMachine
  • 2@ScxmlSub1@isSub1@ID_SUB_1 - highlight state isSub1 in statechart ScxmlSub1 when invoke Id is ID_SUB_1
  • 12@CalculatorStateMachine@operand1|0 - highlight the first transition from operand1 state in statechart CalculatorStateMachine

You can also trace the execution of the chart and use breakpoints.

Local debugging

ScxmlEditor starts a testing application, intercepts its command line output and may communicate in two modes:

  • UDP mode (receives UDP commands and sends events as UDP packages to testing application)
  • Pipes mode (since version 2.1.8) (capture enter-exit events from console output by regexp, and submit trigger event to state machine to console input)

There are two ready-to-use testing applications:

  1. Based on USCXML framework. Supports null, lua, ecmascript datamodels

  2. QtScxmlTester - based on Qt SCXML framework Supports null, ecmascript datamodels

Also you may write your own testing application using the corresponding API

External debugging

In this mode ScxmlEditor only listens UDP commands for highlighting states and displaying messages in CallStack panel

Breakpoints

BreakpointsImage

It was an old dream to monitor state machine workflow without any external dependencies in Qt and finally it comes true. We prepared some native SCXML SVG monitors:

StopWatchDemo

Since ScxmlEditor 2.2.1 you can export SCXML to SVG, include only monitor headers in your app and create monitor instances any time.

NOTICE: While state machine pointer is not set, the monitor does nothing and can be left in Release.

Qt SCXML External Debugging with ScxmlEditor

For Qt SCXML applications you may include scxmlexternmonitor2.h header to your project and follow the instructions

Example of debugging Qt Calculator-QML project

MonitorQML1

  1. Select Run->Start listening from external application
  2. Select Run->Run
  3. Launch Calculator-QML.exe
  4. Use Pause for tracing (optionally)
