Description
When the user double-clicks the node in the tree, the event handler is called to allow editing. This function is optional.
The function can return a
false value, which indicates that the event handler is not defined. In this case, double-
clicking causes the default behavior, which expands or collapses the tree nodes.
Arguments
componentRec
• The componentRec argument is an object that contains the following properties:
• The name property is the name of the tree node item.
• The image property is an optional icon for the tree node item. If this icon is omitted, Dreamweaver uses a default icon.
• The hasChildren property is a Boolean value that indicates whether the tree node item is expandable: if true ,
Dreamweaver displays the Plus (+) and Minus (-) buttons for the tree node item; if false , the item is not
expandable.
• The toolTipText property is an optional tooltip text for the tree node item.
• The isCodeViewDraggable property is a Boolean value that indicates whether the tree node item can be dragged
and dropped into Code view.
• The isDesignViewDraggable property is a Boolean value that indicates whether the tree node item can be dragged
and dropped into Design view.
Returns
Nothing.
Example
In the following example, the extension has a chance to handle a double-click on the tree node item; if it returns the
value
false , the default behavior is to expand/collapse the nodes.
