Displaying text/values on action Buttons

[Dwargh]

Hi, I'm new to lua. Did read and create the learning addons in the book "Hacking World of Warcraft" by Atlas author Dan Gilbert and PerfectRaid author James Whitehead II.

I know there are ways to display values to an actionbutton. I'd like to know how.
I have looked in the code of addons like Macaroon and Dr.Damage but I can't see/don't understand what have been done to what I want.

A code snippet with an explanation on how to do this would be great.

I also want to be able to add this text/value to a button no matter what action bar addon is being used. But that's something for later. For now I just want to be able to display a custom text on a button at a custom position.

You need to create a fontstring object and anchor it to the button.
For example if the action button's global name is ActionButton1 you would do something like:

local text = ActionButton1:CreateFontString(nil,"OVERLAY")
text:SetFont("Fonts\\FRIZQT__.TTF",12) -- font face and size
text:SetText("myText")

-- Here you place the text in the center of the button
text:SetPoint("CENTER",0,0)
