[HELP] Getting window's position?

claudekennilol

I've got a movable window that I'm trying to save off the position of. The window is defined in its own GuiXml. In its TopLevelControl I've given it a name. I was assuming that with its name I could access it from the .lua file via that name. Maybe that's the part I'm missing. I've got my method plugged in the OnMoveStop element and I know the method is firing off. I just can't get through this thread-bare API with its broken search and find anything useful.
So if someone could tell me how to get the position of my named window that would be awesome.

if _G["name"] ~= nil then d( _G["name"]:GetAnchor() ) end

Or :GetCenter() returns X, Y
Or :GetTop()
Or :GetRight()
Or :GetBottom()
Or :GetLeft()

To get your offset from GuiRoot center I'd recommend something like this (off the top of my head from work):

local myX, myY = _G["name"]:GetCenter()
local grX, grY = GuiRoot:GetCenter()

Then I recommend calculating your % distance between guiroot's center and top/left edges. That way if GuiRoot re-scales your addon stays relatively in the same position.

EDIT-EDIT: I just found out about the scaling issue so I'm working on recalcuating all of that this weekend for all of my addons. Otherwise I'd suggest you use one of mine as a guide on how I'm reading/using positions of frames. This should hopefully help you get started though.

Thanks, googling for _G shows me that is definitely what I was missing.

But what is d? Is that a method I've defined with the anchor as the parameter being passed in or something else for lua that I'm not yet familiar with?

D dumps data to chat window 1st tab

d for debug, simple enough.

This

if _G["name"] ~= nil then d( _G["name"]:GetAnchor() )

Can simply be this

if name then d( name:GetAnchor() )

So in my .xml in my TopLevelControl's name attribute I can still access it in my .lua file without having to get a reference to it via _G ?

And you're right, I was reading a lua book last night and thought it was odd/interesting how any not null (er nil) object was true.

Anything in _G is also automatically a top-level name. In fact, that's what _G is - the dictionary of things in the top-level Lua namespace.

For instance, if you define a variable without "local", it'll wind up in _G as well. The following two lines are equivalent:

foo = 1
_G["foo"] = 1

Right, but that's what I'm confused about. In my xml I named an element. Does that make it a global variable?

The way ESO handles its UI XML, yes, it does.
