Drag and drop from tag browse tree to power table

Ignition
1

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.

Bumping this thread, would be great if someone could give an example :slight_smile:

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.

Power Table Tags Dropped.proj (19.9 KB)

For a brief explanation: The initialize() function of the power table fires the addListener() custom method, which creates an instance of a custom DropTargetListener. 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.

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:

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.

Hi J.abrante

Could you find another solution?

Thank.

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?
