Tree item context menu

Ignition
1

I want to create a context menu based on where the user right-clicks on the tree view component.
How can I tell what element (if any) the user is right clicking on?

2

The only way is through the selected item or selected path properties of the tree view. If the selected item is -1 nothing is selected. The only problem is when the user right clicks on a different item than the one that is selected. There is no way of detecting that situation right now.

no hidden java class functions/properties I can reference?

Ok, ok. Here you go:if event.button == event.BUTTON3: tree = event.source.getViewport().getView() row = tree.getRowForLocation(event.x, event.y) path = tree.getPathForLocation(event.x, event.y) pathStr = "" if path != None: for item in path.getPath(): pathStr += str(item) + event.source.separationCharacter pathStr = pathStr[1:-1] event.source.setSelectedPath(pathStr) print event.source.selectedPath print event.source.selectedItem

I used Travis’s code, but I found it messes up if the view has been scrolled. Here’s a tweak that uses SwingUtilities to convert the click coordinates to compensate for scrolling in the Tree View.

if event.button == event.BUTTON3:	
	from javax.swing import SwingUtilities
	
	treeViewport = event.source.getViewport()
	treeView = treeViewport.getView()
	viewClick = SwingUtilities.convertPoint(treeViewport, event.x, event.y, treeView)

	row = treeView.getRowForLocation(viewClick.x, viewClick.y)
	path = treeView.getPathForLocation(viewClick.x, viewClick.y)
	pathStr = ""
	if path != None:
		for item in path.getPath():
			pathStr += str(item) + event.source.separationCharacter
		pathStr = pathStr[1:-1]

	event.source.setSelectedPath(pathStr)
	print event.source.selectedPath
	print event.source.selectedItem
