I would like to add a support to drag and drop a tag from tag browse tree to the power table. When I would do the mentioned the path of the tag dragged would store to the table (in dropped column). Have anyone done something similar already? Thank you for your help.

Here’s a sample window I came up with a while back. Note that is pretty low-level Java Swing stuff - so you’re on your own merits to figure out how it all works. Also, don’t even try and call into support about this.

For a _brief_ explanation: The `initialize()` function of the power table fires the `addListener()` custom method, which creates an instance of a custom [`DropTargetListener`](https://docs.oracle.com/javase/7/docs/api/java/awt/dnd/DropTargetListener.html). That custom `DropTargetListener` has an overridden `drop()` function, which actually handles the incoming data.

You could also just do a Power Table in place of the Tag Browse tree and enable drag and drop between the tables.  
Just query against the sqlth\_te table for records with RETIRED IS NULL

is possible to do the same but from tree view?

my solution is:  
The in source component you must create the following function.

```auto
def addDrag(self):
    """
	Arguments:
		self: A reference to the component instance this method is invoked on. This argument
		  is automatic and should not be specified when invoking this method.
	"""
	from java.awt.dnd import DragSource,DragGestureListener
	from java.awt.dnd import DragSourceListener 
	from java.awt.dnd import DnDConstants
	from java.awt.datatransfer import Transferable
	from java.awt.datatransfer import StringSelection
		
		
	class MyDragGestureListener(DragGestureListener):
		def __init__ (self,table):
			DragGestureListener. __init__ (self)
			
		def dragGestureRecognized(self,DragGestureEvent): 
		 	transferable = StringSelection("");
			myDragDrop.startDrag(DragGestureEvent, DragSource.DefaultCopyDrop, transferable, myDragSourceListener)
	
	class MyDragSourceListener(DragSourceListener):
		def __init__ (self,table):
				DragSourceListener. __init__ (self)
		
	class MyDragDrop(DragSource): 
		def __init__ (self,table):
			DragSource. __init__ (self)
			self.table = table
			
	myDragGestureListener = MyDragGestureListener(self)
	myDragSourceListener = MyDragSourceListener(self)
	myDragDrop = MyDragDrop(self)
	myDragDrop.createDefaultDragGestureRecognizer(self,DnDConstants.ACTION_COPY_OR_MOVE, myDragGestureListener)
	

```

If your component have a extension function “initialize” put there “event.source.addDrag()”. but it’s not present you can put in the eventHandrles MousePressed.

In the destination component you have write this code:

```auto
def addListener(self):
	"""
	Arguments:
		self: A reference to the component instance this method is invoked on. This argument
		  is automatic and should not be specified when invoking this method.
	"""
	from java.awt.dnd import DropTargetListener, DropTarget
	from com.inductiveautomation.factorypmi.application.components.chart.easychart import ClientNodeListTransferable

	class MyDragDropListener(DropTargetListener):
		def __init__ (self, table):
			DropTargetListener. __init__ (self)
			self.table = table
			
		def drop(self, e):
			e.acceptDrop(e.getDropAction())			
			print "dropped"

	
	myDragDropListener = MyDragDropListener(self)
	DropTarget(self, myDragDropListener)

```

In function drop you put the code what do with the information arrive from dop.  
If your component have a extension function “initialize” put there “event.source.addListener()”. but it’s not present you can put in the eventHandrles MouseEntered.

this is the solution do for my request

Becarefull, in Ignition 8.0 : **ClientNodeListTransferable** doesn't exist anymore.

Not right now. But during the summer I have to make the conversion from 7.9 to 8.1 so I will have to solve this problem for sure. Let’s stay in touch, the first one who finds the solution publishes it. What do you say?

You may be able to use this as a starter

> Perhaps you were correct? This turned out to be a bit simpler than I was originally thinking. Not trivial, but not really painful either. Add an extension function to your list component, I called mine addDropListener. Then in the script add the following script: from java.awt.dnd import DropTargetAdapter, DropTarget from com.inductiveautomation.ignition.client.tags.dnd import ListOfQualifiedPath class customDragDropListener(DropTargetAdapter): \_comp = None def \_\_init\_\_(self,comp): D…
