I have a used a custom property of window to find weather that window is pinned or not. When i click on Button, it go through below script and find all opened window, points to the custom property. However for the instance of same window it doesn't work. it reads the same value as previous for instance of window. #Get Windows name that button is on WindowName = system.gui.getParentWindow(event) #Get Current maximize window name CWindowName = system.nav.getCurrentWindow() #Convert to String stringsearch = str(WindowName) #Check if it a drop Menu configuration if event.source.parent.parent.DropMenu==False: #This is NOT a drop menu #Search String for drop menu, then close drop menu if stringsearch.find("Menu\_") \> -1: #Close Parent window system.nav.closeWindow(WindowName) ``` #Close All open Pop ups # change v2.1.221012 #Get all open window names windows = system.gui.getOpenedWindowNames() #system.gui.messageBox( 'There are %d windows open' % len(windows)) for path in windows: window= system.gui.getWindow(path) system.gui.messageBox( str(window)) if path != CWindowName and window != WindowName : WinPinned= window.getRootContainer().temp_WinPin system.gui.messageBox( str(WinPinned)) if WinPinned is False: system.nav.closeWindow(window) ``` ![btnscript](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/2/0286a7c9cadb9d6e7466229ae552e468597feecb.png) ---

Don't use `system.gui.getOpenedWindowNames()`. That obviously can't distinguish between multiple windows of the same name. Instead, use `system.gui.getOpenedWindows()`, which delivers all of the window **objects** present. Check each window **object**'s `.path` property to see which it is. Use that object's `.rootContainer` to then inspect its contents. ---

Hi, I want to do the same thing in Perspective. what can I use instead of "system.gui.getOpenedWindowNames()", as this not perspective supported function. ---

Perspective doesn't have windows. It has pages and views. Look under the `system.perspective.` section of the manual for alternatives. (They won't work the same way. That is, you won't get page or view **objects**. Perspective doesn't expose those.) ---

Hi, I write down following script to find open Pages in Current Session. See Attached image. though I can only list PageIds for open pages. How can I access each page using this page ID list. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/0/c00bc3244f1242eaf709f333450c865a91901b80.png) ---

> [@snehal.raj](#): > > How can I access each page using this page ID list. You can't. Perspective only exposes its objects **within** the relevant environment. Send a message with the proper scope to each page. Do the per-page logic in a message handler within the page. ---
