Taking UIScale into account when calculating width?

[iindigo]

Hey guys,

I'm creating a frame in my addon that fills the width of the screen. To do this, of course, I need to set the width of the frame to the width of the current screen resolution.

But there is the nasty little problem of UI scale. How can I take the user's UI scale into account when calculating the width for my frame?

Why not just do frame:SetPoint("LEFT", UIParent, "LEFT", 0, 0); frame:SetPoint("RIGHT", UIParent, "RIGHT", 0, 0) which should work.

Well, alright, I left something out of my original post for the the sake of simplification.

What I'm building is made up of three pieces: two endcaps and a middle tiling fill. The endcaps are in place and work fine, but in order to set the middle piece's width appropriately I need the screen width with UI scale factored in.

Anchor the tiling to the endcaps.

you could make a frame which goes behind the ends and stretches out 2000 px or so, to cover any resolution. unless it's tiled.

frame:SetPoint("LEFT", UIParent) frame:SetPoint("RIGHT", UIParent) suffices.

Actually, that's part of the reason I need to do this. I'm having to rewrite one of my personal addons because it no longer works with my new display's resolution (2560x1440), as it was designed for 1680x1050. I want to do it in a way that I won't need to rewrite it again; that is, it will function correctly regardless of resolution.

And yes, it's tiled.

If you don't anchor your frame to the UIParent you could always just use WorldFrame:GetWidth() but if you really need to get the width with scale then you'll need to wait till VARIABLES_LOADED has fired and then you can check UIParent:GetWidth()
