How to get Edge of screen

[gorillaz09]

I'm making an addon and I need to know how close my frames are to the edge of the screen. I can easily get it from frame:GetBottom() and frame:GetLeft() but GetTop and GetRight returns the max height and width of my resolution. How can I make a general function to check if I'm close to the top or the right side of my screen?

if frame:GetLeft() < 10 then
   print("close to left")
elseif frame:GetBottom() < 10 then
   print("close to bottom")

elseif frame:GetTop() -- ??

I'm using this in some of my addons to find which side is closer.
I can easily be adapted for finding if top or bottom is closer.

Note that it tells you which side is closer without trying to qualify what is "close",
just that "my frame is positioned closer to left side of screen than to right side of screen"

local function findSide(frame)
	local side = "left";
	local rightDist = 0;
	local leftPos = frame:GetLeft();
	local rightPos = frame:GetRight();
	if ( not rightPos ) then
		rightPos = 0;
	end
	if ( not leftPos ) then
		leftPos = 0;
	end
	rightDist = GetScreenWidth() - rightPos;
	if (leftPos and (rightDist < leftPos)) then
		side = "left";
	else
		side = "right";
	end
	return side
end

Also note that because I use it to decide an anchor point the returns might be a little confusing at first.
I.e if it finds that my frame is closer to the right side it returns "left" as in:
"we're closer to right = have more space on the left, anchor things there".

thanks! that's more or less what I was looking for
