About the Dataflow Toolbox
The Dataflow Toolbox is an interface for placing new virtual variables, virtual lines or virtual surfaces and other dataflow objects into the Dataflow Window. These objects are classified in the Dataflow Toolbox menu pane according to their type, and there is a text box for you to search for items by name.
Opening the Dataflow Toolbox
To view the Dataflow Toolbox, click the
- Dataflow Toolbox icon
, or - the View menu then select Dataflow Toolbox.
You can dock or float the Dataflow Toolbox panel.
Create a dataflow object
- Open the Dataflow window.
- Open the Dataflow Toolbox.
- During creation, the displayed operators are filtered by the type of objects in the Dataflow window and are futher filtered by the presence of a pre-selected object(s). Pre-selected objects are connected as operands. When there are no pre-selected objects, a virtual variable or object is created without connected operands. It is worthwihile to review the suitablility of the operands for a new virtual variable or object.
- Select an item from the menu pane and drag and drop it into the Dataflow window.
Customize the variable settings via the corresponding
Exporter Properties dialog box,
Variable Properties dialog box,
Surface Properties dialog box,
New Surface dialog box (with the Surface pick from current variable item),
Platform Properties dialog box
