Assign atlas texture to button in lua?

I found that the equivalent to xml

Code:

<Button name="myButton">

  <NormalTexture file="Interface\Buttons\UI-SpellbookIcon-PrevPage-Up"/>

  <PushedTexture file="Interface\Buttons\UI-SpellbookIcon-PrevPage-Down"/>

  <DisabledTexture file="Interface\Buttons\UI-SpellbookIcon-PrevPage-Disabled"/>

  <HighlightTexture file="Interface\Buttons\UI-Common-MouseHilight" alphaMode="ADD"/>

</Button>

can be achieved in lua as follows:

Code:

local myButton= CreateFrame("Button", "myButton", myParentFrame)

myButton:SetNormalTexture("Interface\\Buttons\\UI-SpellbookIcon-PrevPage-Up")

myButton:SetPushedTexture("Interface\\Buttons\\UI-SpellbookIcon-PrevPage-Down")

myButton:SetDisabledTexture("Interface\\Buttons\\UI-SpellbookIcon-PrevPage-Disabled")

myButton:SetHighlightTexture("Interface\\Buttons\\UI-Common-MouseHilight", "ADD")

But how do I achieve a texture defined as "atlas" in lua?

Code:

<NormalTexture atlas="QuestCollapse-Show-Up"/>

<PushedTexture atlas="QuestCollapse-Show-Down"/>

I tried

Code:

local texture = myButton:CreateTexture()

texture:SetAtlas("QuestCollapse-Show-Up")

myButton:SetNormalTexture(texture)

but this did no show any texture.

What am I missing? Thanks!

There are methods for button objects that seem they would achieve this (never used them myself):
SetNormalAtlas
SetPushedAtlas
SetDisabledAtlas
SetHighlightAtlas

Ah cool! Thanks! There is odly nothing about these functions online...

Can anyone tell me why the Atlas texture is apparently always somewhat larger than the Texture texture?

Code:

local myButton = CreateFrame("Button", nil, myParent)

myButton:SetNormalAtlas("QuestCollapse-Show-Up")

myButton:SetPushedTexture("Interface\\Buttons\\UI-SpellbookIcon-NextPage-Down")

myButton:SetSize(25, 25)

How could I make them the same size?

I'd say mess with SetTexCoord until it looks ok:

Code:

local myButton = CreateFrame("Button", nil, myParent)

myButton:SetNormalAtlas("QuestCollapse-Show-Up")

myButton:SetPushedTexture("Interface\\Buttons\\UI-SpellbookIcon-NextPage-Down")

myButton:GetPushedTexture():SetTexCoord(0.1, 0.9, 0.1, 0.9)

myButton:SetSize(25, 25)

OK, that's an idea.

But let me ask differently.

How can I achieve that the highlight Texture texture is shown as big as the normal Atlas texture?

XML:

Code:

<NormalTexture atlas="QuestCollapse-Show-Up"/>

<PushedTexture atlas="QuestCollapse-Show-Down"/>

<HighlightTexture file="Interface\Buttons\UI-Common-MouseHilight" alphaMode="ADD" setAllPoints="true">

  <Size x="48" y="48"/>

  <Anchors>

    <Anchor point="CENTER"/>

  </Anchors>

</HighlightTexture>

Lua:

Code:

myButton:SetNormalAtlas("QuestCollapse-Show-Up")

myButton:SetPushedAtlas("QuestCollapse-Show-Down")

myButton:SetHighlightTexture("Interface\\Buttons\\UI-Common-MouseHilight", "ADD")

--???

Same deal, adjust SetTexCoord arguments until it looks ok:

Code:

local myButton = CreateFrame("Button", nil, UIParent)

myButton:SetNormalAtlas("QuestCollapse-Show-Up")

myButton:SetPushedTexture("Interface\\Buttons\\UI-SpellbookIcon-NextPage-Down")

myButton:GetPushedTexture():SetTexCoord(0.1, 0.9, 0.1, 0.9)

myButton:SetHighlightTexture("Interface\\Buttons\\UI-Common-MouseHilight", "ADD")

myButton:GetHighlightTexture():SetTexCoord(0.15, 0.85, 0.15, 0.85)

myButton:SetSize(25, 25)

Ah, now I get it! Thank you very much!
