There are two tree node shapes on the Common Controls stencil: Tree node (top level) and Tree node (child). To build a tree structure, connect child shapes to top level shapes.
Tree node (top level)
There are three connection points on the Tree node (top level) shape. One for a sibling node, one for a child node, and one for a Small icons shape.
Connect a Tree node (child) shape to this connection point to create a sibling node.
Connect a Tree node (child) shape to this connection point to create a child node.
Connect a Small icons shape to this connection point to add an icon to the node.
Tree node (child)
The Tree node (child) shape has extension lines that trace a path to the nodes they're connected to. Use the control handle to extend the lines.
Extension lines trace the path from child node to top-level node.
Control handle for extending lines.
To adjust the spacing between two nodes, select one of the shapes and drag the control handle.
To hide or show the branch lines, right-click the shape and click Show Branch Lines.
Note: If you don't see the branch lines in your drawing, try turning off the grid by clicking Grid on the View menu.
Collapsed (+) indicates that there are nodes hidden under this one.
Expanded (-) indicates that all the nodes directly under this one are visible.
Non-expanded (no +/-) indicates that there are no nodes under this one.
Make Room for Icon leaves room to glue a Small icon shape to the connection point directly left of the node.
Show Branch Lines hides or shows the faint lines that connect the child shapes to the top-level shapes.
Notes: If there isn't room for an icon or you don't see the connection point, right-click the shape and check the Make Room for Icon box.
If the tree node is Expanded (-), choose an Open folder for the node. If it's Collapsed (+), choose a Closed folder.
