Is there a way to tell if a window is active?

[elgs]

I'm hoping to build a windows like desktop. I found setActive useful on the Ext.window.Window. However, it seems it's missing an isActive method. My question in other words would be: Is there a way to tell if a window is active, or is on top of all other windows? Thanks.

The window manager can assist

Thank you, @dawesi. That's exactly what I'm looking for.
