Short Name: Edit Tree Items.Add Item
Requires: Base Development System
Class: TreeControl Methods
To Use: Create a method.
Adds an item to the tree control.
This method is similar to the Insert Item Before item on the shortcut menu of a tree control.
|Parent Tag||No||Unique tag of the item under which you want to add the new item. The default is an empty string, which adds the item to the highest level in the hierarchy. Avoid wiring string constants to the input of the Parent Tag parameter. Instead, use a tree control property or method that provides the unique tag of the item under which you want to add the new item.|
|Child Position||No||Sets where to place the new item in relation to the item whose tag you wire to Parent Tag. Wire a value of 0 (default) to place the new item directly under the parent item. Wire a value of 1 to place the new item under the first child item, a value of 2 to place the new item under the second child item, and so on. Wire a value of –1 to place the new item under the last child item. If the value you wire to this input is greater than the number of child items under the parent item, the method places the new item under the last child item.|
|Left Cell String||No||Text to display in the leftmost cell for the new item. The default is an empty string.|
|Child Text||No||Array of strings to display in the remaining cells for the new item. The default is an array of empty strings.|
|Child Tag||No||Unique tag for the new item. The default is the string you wire to Left Cell String. If an existing tag already uses that string, LabVIEW appends a number to the string to create a unique tag for the new item. You cannot create a tag that begins with TREE_. All tags that begin with TREE_ are reserved for use by LabVIEW. If the tag you wire to the method begins with TREE_, LabVIEW prepends an underscore (_) to create a valid tag for the new item. If the tag you wire to the method begins or ends with white space or non-printing characters, such as a tab or new line, LabVIEW removes the white space or non-printing characters.|
|Child Only?||No||If TRUE, you cannot indent other items under the new item. The default is FALSE. This property is similar to the Child-Only Item item on the shortcut menu of a tree control.|
