Since the size of a window is not a bindable property, I can not use it as a property change event for when the size of my window changes. I came across a post which suggested adding a listener would do the job:

[The aforementioned useful post](http://forum.inductiveautomation.com/t/propertychange-event-when-window-change-it-size/11369/4)

Although the links to explain the java listener were very good and comprehensive, I could not work out how to add it to my window. I believe it needs to be added in the custom method section. But could you please show me a basic example of how one would add a listener in there?

Many thanks!!!

Add the following to your visionWindowOpened event. Change the methods are required, and remove ones that are not needed.

```auto
from java.awt.event import ComponentAdapter
class MyListener(ComponentAdapter):
	def componentResized(self,e):
		print e
	def componentShown(self,e):
		print e
	def componentHidden(self,e):
		print e
	def componentMoved(self,e):
		print e
event.source.addComponentListener(MyListener())

```

If you have any questions, please do not hesitate to ask.
