So I am implementing an override (that I don't agree with but that's not my decision) and I came across
while trying to get my work going.
x = Ext.lib.Event.getPageX(e),
I was not familiar with Ext.lib so I started looking through all the ext code and I never see it namespaced or set up anywhere...it just seems to start existing about 2200 lines into the code.
Anyone have any ideas what this is? I'm sure it's important. It's referenced all over. Ext.lib.Event, Ext.lib.Ajax, Ext.lib.Dom, etc. but I can't figure out what it's supposed to be for in the larger scheme.
Thanks for any help on this one.
