Using SetTexture on a texture with no name?

[iindigo]

Is this possible? I'm trying to modify one of the default Blizzard frames, but after looking at the XML for said frames, the textures of the window are not named at all.

Thanks!

One way would be to retrieve the table with GetRegions()

Where could one find examples of this? I've never worked with regions before. I did a quick google and wowwiki search, which turned up some things but it's confusing to someone who doesn't know how regions work...

GetRegions just returns all non-Frame objects (FontStrings and Textures) that are a child of the frame. Just iterate through the returned objects to find yours.

for _, obj in pairs{frame:GetRegions()} do 
     -- You have to use your own heuristic to find the frame. For example if you know that the
	 -- texture file is the default status bar texture, you could use this to find it:
	 if obj:GetObjectType() == 'Texture' and obj:GetTexture() == 'Interface\\TargetingFrame\\UI-StatusBar' then
		-- This is the frame we want, manipulate it here.
	 end
end

You should also be able to do this instead of using a throw-away table:

for i = 1, select('#', frame:GetRegions()) do
	local obj = select(i, frame:GetRegions())
	-- Same code as above
end

But if this is only something your doing once then I don't think it matters which way you choose.

Thanks for the example! It's been a great help. However, it seems that this method doesn't work on PaperDollFrame, or I'm doing something wrong.

	for _, obj in pairs{PaperDollFrame:GetRegions()} do 
	 if obj:GetObjectType() == 'Texture' and obj:GetTexture() == 'Interface\\PaperDollInfoFrame\\UI-Character-CharacterTab-L1' then
		obj:SetTexture("Interface\AddOns\xXXXx\charPaneTopLeft.blp");
	 end
	end

Am I doing anything wrong here? The code is definitely being fired, I made sure of this myself. The pane simply shows no change after the code fires, though.

Replace:

obj:SetTexture("Interface\AddOns\xXXXx\charPaneTopLeft.blp)

with:

obj:SetTexture("Interface\\AddOns\\xXXXx\\charPaneTopLeft")

Ah! That indeed was it. I thought double slashes weren't necessary since I didn't have to use them when creating textures in XML.

Thanks a ton guys!

Backslash is an escape character for strings in lua, so that's why you need the additional one. You can also use a literal string for file paths, which ignores escape characters:

[[My\File\Path\Here.blp]]

But this is just me being a little pedantic again, since there isn't any difference between the two options for this particular situation. :>
