Model tools

Model tools toolbar contains the frequently accessed tools for capturing, modification and simulation of the graph models.

Generic tools

Some of the tools are implemented in the core of Workcraft and are available in all the plugins. Thes include selection, connection and text note tools.

  • [S] Selectselection tool
    - a tool selecting, moving, deleting, grouping, the model elements. This tool can also be activated by pressing S. When the selection tool is active you can select the graph elements and modify them as follows.
    • Click a graph element to select it. Outline a rectangular area to select several elements. Outline from-right-to-left for adding fully covered elements and from-left-to-right for adding any touched elements.
    • Hold Shift to include elements into selection and Ctrl to exclude elements from selection.
    • Press Ctrl+A to select all components (Edit→Select all). Press the exclamation mark to inverse the selection (Edit→Inverse selection). Press Esc to resets the selection (Edit→Deselect).
    • Selected components can be removed by pressing Delete (Edit→Delete), cut by pressing Ctrl+X combination of keys (Edit→Cut), copied by pressing Ctrl+C keys (Edit→Copy), and a previously copied part of a model may be inserted by pressing Ctrl+V combination of keys (Edit→Paste).
    • Double click inside a group to enter it (same action as Page↑). Double-click outside the current group to go one level up (same action as Page↓).
    • Use left mouse button or , , , to move selected components.
  • [N] Text Notetext note generator
    - a tool for creating textual comments. This tool can also be activated by pressing N. When this tool is active click on the graph editor area to create a new textual comment.
  • [C] Connectconnection tool
    - a tool for connecting the model nodes with arcs. This tool can also be activated by pressing C.
    • When the connection tool is active, click on the source node to initiate a connection, then click on the destination node to complete the connection. You can hold Ctrl key to connect nodes in continues mode, so that each destination node becomes a source node for the next connection.
    • Connections are normally straight lines between the nodes. However, by double-clicking on a connection an corner point can be created. It is shown as a small dot when the connection is selected and can be dragged into its chosen position, with its connection lines following it.
    • The connection can also be curved by selecting an existing connection, and changing the type of the connection from Polyline to Bezier in the Property editor.

Specific tools

Most of the tools are model-specific and are implemented by the corresponding plugin. For example, the Directed Graph plugin implements a basic vertex generator tool while the Petri net plugin implements place generator, transition generator and simulation tools.

  • [V] Vertex - vertex generator
    - a tool for creating a vertex of a directed graph. This tool can also be activated by pressing V.
  • [P] Place - place generator
    - a tool for creating a place node of a Petri net. This tool can also be activated by pressing P.
  • [T] Transition - transition generator
    - a tool for creating a transition node of a Petri net. This tool can also be activated by pressing T.
  • [M] Simulate - simulation tool
    - a tool for simulating the Petri net model. This tool can also be activated by pressing M.
