Toolbox allows to build a Flowchart with drag-and-drop operations. It includes tools for selecting, moving and connecting Blocks.

XFL Canvas

---

XFL Canvas is the pane in the center of the Studio window where a Flowchart is drawn. XFL Canvas may have multiple tabbed worksheets. All worksheets belong to the same Flowchart. A new XFL Canvas is created with the initial empty worksheet S1: Main. Additional worksheets can be added from a context menu of the existing worksheet tab or by selecting Edit >> Sheets command from the main menu. Flowchart fragments spread over multiple tabbed worksheets belong to the same Flowchart. State Blocks and Reference Blocks link them together.

Objects Browser

---

Objects Browser is a vertical pane at the right side of the Studio window. It provides a hierarchical view of all PDUs defined for supported protocol layers. The pane allows user to interactively navigate through the descriptions of the protocol fields, and look up the types, default values, constraints, etc.

One can Copy/Paste PDUs from Object Browser to XFL Canvas to create boiler-plate Send and Receive Blocks for the PDU.

Execution Log

Execution Log pane is a horizontal pane at the bottom of the Studio Window. It displays detailed real time debugging data.
