Representation of a schema

Change 2D representation of a schema

The schema consists of several nodes of control and computation types. These nodes have input and output data, stream and control ports. Connecting these ports by links means transferring data from output port to input port of a next node.

At the current moment YACS GUI for SALOME provides the user with only one view mode of a schema.

  • Full view. Nodes are “fully” displayed, with all ports and information labels. All links between connected ports are shown.


Full view of a schema

Within YACS module the user can zoom-in and zoom-out 2D schema presentation interactively with the mouse, fit 2D presentation of a schema into 2D Viewer bounds (Fit all operation) and pan content of 2D Viewer (Panning operation) interactively with the mouse. These commands are accessible from View Operations toolbar.

The user can also use the mouse wheel button to zoom in and out and the arrow key for panning.

The user can also zoom inside a composed node by using the zoom to bloc command from the node context menu.

Use Fit all operation to go back to full view.

Auto-arrange schema nodes

It is a very useful operation, because it simplifies the schema presentation in the schema 2D Viewer and makes it easier for the user perception. This operation is applicable to the whole schema (arrange nodes recursion command from the schema context menu) or only to some parts of the schema (arrange local nodes command from a composed node context menu).

Shrink/Expand nodes

This functionality allows folding/unfolding any node(s) in order to decrease the schema size. It can be useful if user deals with a large schema that contains a lot of number of nodes.

There are 3 possible ways to make the schema more compact:

  • call shrink/expand context menu or double mouse click on any node to fold/unfold this node;

  • call shrink/expand children context menu or Ctrl + double mouse click on any composed node to fold/unfold all direct children nodes of selected node;

  • call shrink/expand elementary context menu or Ctrl + Shift + double mouse click on any composed node to fold/unfold all elementary nodes of selected node recursively.
