Description

The TextField class is used to create display objects for text display.

Examples

Example 1: bitmap font.

local textfield = TextField.new(font, "some text")
stage:addChild(textfield)
textfield:setText("some other text") -- change the text


Example 2: default font.

-- to use the default font, pass nil value for the font parameter
local textfield2 = TextField.new(nil, "some text with default font")
stage:addChild(textfield2)


Example 3: TTFont.

local font = TTFont.new("fonts/Tahoma.ttf", 32, "", true, 1)
local text = TextField.new(font, "This is a text")
text:setPosition(100, 100)
stage:addChild(text)


Example 4: colored text.

local text = TextField.new(nil, "This is a \e[color=#f005]semi transparent red\e[color] text")
text:setPosition(32, 64)
stage:addChild(text)
