Button.font read/write property
Get the Button font, a string value that represent the font name.
To set the Button.font property, you can assign a string that represent either a font name of an installed system font, or a font file (*.ttf, *.fon...).
A File can also be provided, representing a font file.
Note that only the font family is changed. The font style and font size are not affected (see the Button.fontstyle and the Button.fontsize properties).
Example
local ui = require "ui"
-- create a simple window
local win = ui.Window("Button.font sample", 320, 200)
local button = ui.Button(win, "", 40, 70)
button.font = "Times New Roman"
button.fontsize = 12
button.text = "Button in '"..button.font.."' "..button.fontsize.."px"
win:show()
-- update the user interface until the user closes the Window
repeat
ui.update()
until not win.visible
