Handling a TreeView control at run time

Operations performed by the user on a TreeView control
When the TreeView control is in edit, the user can expand or collapse the different levels of the tree structure by clicking the treeview elements.

To expand a level, you must:

  • click the "+" sign found in front of the name of the element.
  • double-click the node to expand.
To collapse a level, you must:
  • click the "-" sign found in front of the name of the element.
  • double-click the node to collapse.

Associated processes
Several processes are run whenever the treeview elements are handled by the user. See Processes associated with a TreeView control for more details.
