Is there a way to get the parent window in a custom method, similar to system.gui.getParentWindow(event) without passing in a parameter?

SwingUtils is your friend:

> [@onDoubleClick Extension Function](http://forum.inductiveautomation.com/t/ondoubleclick-extension-function/17961/10):
>
> Java’s [SwingUtilities](https://docs.oracle.com/javase/8/docs/api/javax/swing/SwingUtilities.html#getAncestorOfClass-java.lang.Class-java.awt.Component-) can help. Place the following in a script module, shared.swing, perhaps: from javax.swing import SwingUtilities from com.inductiveautomation.factorypmi.application import FPMIWindow def getParentWindow(component): return SwingUtilities.getAncestorOfClass(FPMIWindow, component) Then in your extension function, you can do: w = shared.swing.getParentWindow(self) v = w.rootContainer.customProperty
