Description
The Tag Browse Tree component is similar to the Tag Browser in the Designer, allowing tags to be browsed in both the Designer and the Client, and dragged on to other components like the Easy Chart. Unlike the Tag Browser, tags can not be edited, tag properties can not be displayed, and UDT definitions can not be displayed. Tags in the component can be refreshed through scripting by calling refresh().

Root Node Path

The path of the root of this tree structure, or "" if no selection. When intentionally setting the root node, the exact syntax changes depending on what the Tag Tree Mode property is set to:

Realtime Tag Tree: [TagProvider]FolderPath/

The example below is using the "default" tag provider, and a folder named "machine_1"

Example
[default]machine_1/


Historical Tag Tree: [DatabaseConnection/GatewayName:TagProvider]FolderPath/

The example below is using a database connection named "DB", the system name of the Gateway is "ignition", the tag provider is "default" and will set the path to a folder named "machine_1"

Example
[DB/ignition:default]machine_1/

Event Handlers

Examples
Code Snippet
# The following code shows a right-click popup menu.
# Add these lines after the """ """ section of the createPopupMenu extension function. 
# Note how lines below are indented, the first def command should line up with the
# indentation of the """ """ section of the Extension Function.
 
	def showValue(self):
		value = str(clickedTag.value.value)
		system.gui.messageBox(value)


	def showLastChange(self):
		lastChange = str(clickedTag.value.timestamp)
		system.gui.messageBox(lastChange)

	itemsDict = {"Show Value": showValue, "Show Last Change":showLastChange}
	JPopupMenu = system.gui.createPopupMenu(itemsDict)
	return JPopupMenu

    self passed to the right click are not a reference to the calling component.

    If you need access to the component in the functions you must pass it like def showValue(self,comp=self)
