FrameXML $parent

Thanks Seerah. It appears the aforementioned frames are childless. Printing GetChildren() against them doesn't return anything, and doing so against their parents doesn't return anything that /framestack didn't already reveal.

What's more confusing to me, is that in running the below code, I expected *all* UI textures to be affected:

local abc = function()
    for i, v in pairs(_G) do
        if type(v) == "table" then
            local meta = getmetatable(v)
                if meta
		and meta.__index
		and type(meta.__index) == "table"
		and meta.__index.GetTexture
		and v:GetObjectType() == "Texture"
		then		
                    v:SetDesaturated(1)
		    v:SetVertexColor(1, 0, 0)
                end
        end
    end
end

But this hodgepodge is what results (some textures left completely untouched, some desaturated but not recolored ):


My total inexperience with global tables aside for a sec , it feels like there is a methodology to solving this that I'm totally missing.

Another example (Clock button: \Blizzard_AddOns\Blizzard_TimeManager\Blizzard_TimeManager.xml):

	<!-- Minimap button to access the TimeManagerButton -->
	<Button name="TimeManagerClockButton" parent="Minimap">
		<Size x="60" y="28"/>
		<Anchors>
			<Anchor point="CENTER">
				<Offset x="0" y="-75"/>
			</Anchor>
		</Anchors>
		<Layers>
			<Layer level="BORDER">
				<Texture <!-- no texture name --> urgency="5" file="Interface\TimeManager\ClockBackground" setAllPoints="true">
					<TexCoords left="0.015625" right="0.8125" top="0.015625" bottom="0.390625"/>
				</Texture>
			</Layer>
			<Layer level="ARTWORK">
				<FontString name="TimeManagerClockTicker" inherits="GameFontHighlightSmall">
					<Anchors>
						<Anchor point="CENTER">
							<Offset x="3" y="1"/>
						</Anchor>
					</Anchors>
				</FontString>
				<Texture name="TimeManagerAlarmFiredTexture" urgency="5" file="Interface\TimeManager\ClockBackground" alphaMode="ADD" hidden="true" setAllPoints="true">
					<TexCoords left="0.015625" right="0.8125" top="0.51625" bottom="0.890625"/>
				</Texture>
			</Layer>
		</Layers>
		<Scripts>
			<OnLoad function="TimeManagerClockButton_OnLoad"/>
			<OnEnter function="TimeManagerClockButton_OnEnter"/>
			<OnLeave function="TimeManagerClockButton_OnLeave"/>
			<OnUpdate function="TimeManagerClockButton_OnUpdate"/>
			<OnClick function="TimeManagerClockButton_OnClick"/>
		</Scripts>
	</Button>

I guess my question is how do you find a texture object when there is no texture name (i.e., is there a default)? Might there be a way to do it backwards by looking up all of the texture objects using a certain texture file (e.g., Interface\TimeManager\ClockBackground)?

The way is to iterate everything via GetChildren() and GetRegions() starting with UIParent.

Eeek...is there a method you can recommend?

I'm poking around dev tools for something...I don't presume I'm the first to run into this. I have a "global table" dump in xml format from the api highlighter I use, but not sure how comprehensive it is.

In general, is it normal for some objects to exist outside of framexml & blizz addons, and are there tables other than _G I can/should iterate through?

All for a few silly buttons that most folks hide() anyway.

[Aprikot]

print(MinimapZoomOut:GetRegions())

returns

table: 11877CE8 table:1D55E7B8 table: 1BC89C08 table: 1BC89C30

How does one correlate these hex values to names?

[Seerah]

Oops, sorry. Yeah, I meant GetRegions. That's how you get the parts of the clock at least (see PocketPlot).

You can't. All you are doing is printing out the memory address of tables (where each Region returned is a Lua table) and that memory address will be different every time you run WoW. Regions are basically Fontstrings and Textures.

All f:GetRegions() does is give you a list of children textures and fontstrings for frame f, and you can operate on them like any other texture or fontstring. If they have a name, then :GetName() would return a string, otherwise nil is returned.

The regions are returned in the order of creation for the frame in question, so look at the XML and start counting, if you want to figure out which region is which texture you want to modify (such as, I want to modify the 2nd created texture of this frame, so use the 2nd return of :GetRegions() on it and call :SetVertexColor() on it.)

[Aprikot]

Thanks Xinhuan & Seerah for the help (success fir the Zoom Out button texture):

local zotex = select(1, MinimapZoomOut:GetRegions())

I think I'm going to have a long & fruitful relationship with GetRegions()

[Ketho]

local zotex = select(1, MinimapZoomOut:GetRegions())

uhm .. isn't that local arg1 = select(1, table) superfluous

[Aprikot]

It is for the zoom button as the first return is the texture I wanted to recolor. I was using select one at a time to see what was what .

[Aprikot]

Everything I thought I learned in this thread is availing me little in trying to color the TotemFrame button "borders".

I've tried arbitrarily checking args 1-30 (via select()) for both GetRegions() & GetChildren() against each of the TotemFrame* frames shown in the below framestack screenshot (layers 7-10):



I'm now trying to do it via CreateTexture(), and I think there is trouble with the way I'm interpreting TotemFrame.xml:

local frame = CreateFrame("Button", "TotemButtonTemplate", PlayerFrame)
local texture = frame:CreateTexture("$parentIcon", "OVERLAY")

TotemFrame.xml below for reference. I appreciate any help!

You cannot overwrite an XML template by creating a Button in Lua using the same name. Instead, to replace the texture, you would use the absolute name of the texture and modify that:

local texture1 = TotemFrameTotem1IconTexture
local texture2 = TotemFrameTotem2IconTexture
local texture3 = TotemFrameTotem3IconTexture
local texture4 = TotemFrameTotem4IconTexture

texture1:SetTexture(path_to_image)
texture2:SetTexture(path_to_image)
texture3:SetTexture(path_to_image)
texture4:SetTexture(path_to_image)

[Aprikot]

My goal is identification of the texture object(s) being used for the button borders.

TotemFrame.xml does specify hierarchy for TotemFrameTotem1IconTexture for example ($parentTotem1 $parentIcon $parentTexture -- colored below), whereas the border texture appears nameless, and resides in its own nameless frame.

 
            <Frame>
                <Size x="38" y="38"/>
                <Anchors>
                    <Anchor point="CENTER">
                        <Offset x="0" y="0"/>
                    </Anchor>
                </Anchors>
                <Layers>
                    <Layer level="OVERLAY">
                        <Texture file="Interface\CharacterFrame\TotemBorder"/>
                    </Layer>
                </Layers>
                <Scripts>
                    <OnLoad>
                        self:SetFrameLevel(_G[self:GetParent():GetName().."Icon"]:GetFrameLevel() + 1);
                    </OnLoad>
                </Scripts>
            </Frame>

This is what led me to go the GetRegions() route (unsuccessfully thus far). The Lua in my previous post is one of many grasping at straws attempts at capturing the nameless texture.
