Gradients in LUA

Hey guys, just wondering how to create gradients using LUA.

For example, I have a panel created using CreateFrame(), how can I make this panel fade from one side to another?

short answer:
SetGradientAlpha()

so in a nutshell, you just have to create a texture for your frame and then apply SetGradientAlpha method to it.
e.g.
local f = CreateFrame"Frame"
f.t = f:CreateTexture(nil, "PARENT")
f.t = SetTexture(some_texture or 1,1,1,1)
f.t:SetAllPoints(f)
f.t:SetGradientAlpha("HORIZONTAL", 0,0,0,1, 0,0,0,0)
f:SetWidth(some_width_value)
f:SetHeight(some_height_value)

I use this

Code:

local frame = CreateFrame("Button")



--[[frame definitions here]]--



frame.leftGrad = frame:CreateTexture(nil, "BORDER")

frame.leftGrad:SetWidth(16)

frame.leftGrad:SetHeight(14)

frame.leftGrad:SetPoint("LEFT", 0, -5)

frame.leftGrad:SetTexture(1,0,0,1)

frame.leftGrad:SetGradientAlpha("Horizontal", 0, 0, 0, 0.2, 0, 0, 0, 1)



frame.rightGrad = frame:CreateTexture(nil, "BORDER")

frame.rightGrad:SetWidth(16)

frame.rightGrad:SetHeight(14)

frame.rightGrad:SetPoint("RIGHT", 0, -5)

frame.rightGrad:SetTexture(0,1,0,1)

frame.rightGrad:SetGradientAlpha("Horizontal", 0, 0, 0, 1, 0, 0, 0, 0.2)

this makes a 32x14 black gradient that starts from transparent to solid to transparent.
