I have to resign attempting to accomplish what I want to do. There is no way, I know of, to capture pins on the compass unless I directly "faced" the pin (and even then I have to run a pretty heavy polling function). The pin does exists on the compass before "facing" it (picture shows it off to the right side) but it's
far beyond me how to iterate through all pins on the compass.
I kept banging my head against this problem solely because the fact that "if it's displayed on my compass it must be somewhere in the GUI elements."
Anyways, I started writing a new addon, successfully! (lol), that tracks player coordinates and displays a "Road Sign" (just a ToolTip, actually) on [s]keyPress[/s] slash_cmd when the user enters a polygon. I check all vertices and notifications are sent to the user there's a Road Sign ahead if they are within the polygons boundaries. I still need to make the slash_cmd hotKeyed for the ToolTip/Road Sign. I have feeling my road_sign_tbl is going to be gigantic. =)
