Navigator Topology Map Window


When the Navigator button is clicked, it displays the navigational map with an outlined box inside it showing which part of the map is in the current view. By clicking and dragging this box, you can pan across the topology map. This function is ideal for use when you have zoomed in to one section of the topology, and you want to move to other regions at the same zoom level.

The purpose of the drag and rotate tool is to choose some nodes or collapsed groups within a rectangular region, and then stretch, shrink, move, or rotate the rectangle.

To use the tool, click the drag and rotate button. Drag a rectangle on the map around nodes or groups that you want to move. You press Shift to constrain the rectangle to be a square. If no nodes or groups are selected (highlighted in yellow), the system remembers all the nodes and collapsed groups inside the rectangle. Otherwise, if some of the nodes or groups in the rectangle are selected (highlighted in yellow), then the system only remembers the selected nodes or groups in the rectangle. This is useful if you only want to move selected nodes in a rectangle.

When you stop dragging, the rectangle turns green, meaning active. You can then perform one of the following actions:

  • To stretch or shrink the region, drag one of the eight square handles.

  • To move the region, put the mouse inside the green rectangle and drag the rectangle to another location.

  • To rotate the points inside the green rectangle, rotate the mouse wheel. If you do not have a mouse wheel, press Alt and click the left mouse button to rotate the points in one direction. To rotate the points in the other direction, press Alt and Shift and left-click. If you have a middle mouse button, click the middle mouse button to rotate the points one way, and press Ctrl or Shift and click the middle button to rotate the other way. (The rotation is along ellipses inside the rectangle, so if you want true circular rotation, make sure that the rectangle is a square by pressing Shift when you create it.)

There are two ways to end the drag and rotate operation: click outside the green rectangle or click the drag and rotate button to turn it off.

The paths function allows you to view the path between any two nodes in the topology map. To view detailed path information, click Paths in the toolbar. A cross-hair appears. Then select a starting node and move the cross-hair to a destination node and click it. The path information appears in the console window giving detailed information about the path such as the route of the path between two nodes. The following is an example of the detailed path information between two nodes;
