I have a single client with multiple desktops-window opened in some monitors. I want to get the size (w,h) of each monitor, depending of the current monitor where the window appears.  
I’ve been testing some options but I don’t get into the correct one. I used `system.gui.getScreens()`, but I need to identify in a window script which is the index of the current monitor where this windows it’s been shown, but I don’t know how.  
I also tried with:  
`
from javax.swing import JFrame, SwingUtilities
window = system.gui.getParentWindow(event)
frame = SwingUtilities.getAncestorOfClass(JFrame, window)
width=frame.width
height=frame.height
`  
But I get the error  
 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/8/8ca128dd97028ae466cd240ebcb12a34dbeb78b8.png)

also tried`
import java.awt
gd=java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice()
width = gd.getDisplayMode().getWidth()
height = gd.getDisplayMode().getHeight()
`  
But this one only gives the default monitor info. I wish `.getCurrentScreen() ` exists…

I also some other codes but I get errors or not desired behavior.

I need some advices please!!

Have you tried _system.gui.getScreenIndex()_ ?

I not sure how to use it. Please tell me how  
The documentation suggest this output is the index where the function was called. But where show I place the function on the root container of the window itself and which event handler show I use to trigger when ever the client moves between monitors?
