TreeItemType

The TreeItemType object describes a tree node type that, unlike the TreeNodeType, cannot contain additional tree nodes. They represent the leaves of the Tree.

• onAction (String path)

  This event is triggered when the user selects a node of this type. parameter is the path to the relevant context element.

• onDrop (String data, String mimeType, int offset, String path, String tags

  This event is triggered when the user drops an object onto this TreeNodeType. The parameters are:

  • data : The data specified for the drag source.
  • mimeType : the mime type specified for the drag source.
  • offset : the position relative to the index, the user has dropped the object onto.
    • -1: just above the item specified by the index
    • 0: right onto the item specified by the index
    • +1: just below the item specified by the index.
  • path: The tree node is described by a path to the node element representing it. Declare an action and event handler parameter of typeIWDNodeElement(or one of your own node element classes) along with a suitable parameter mapping; then the path will be automatically transformedinto a node element instance. Note: when the tree is empty, no drop will be possible.
  • tags : the tags defined for the drag source
