Label.width | LuaRT free and open source Windows programming framework for Lua

Label.width read/write property

Get or set the Label area width. The width starts from 0 (left side of the Label) and increases to the right direction.

Example


local ui = require "ui"

-- create a simple Window
local win = ui.Window("Label.width sample", 320, 200)
local label = ui.Label(win, ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", 50)
local inc_btn = ui.Button(win, "Increase Label.width !", 15, 50)
local dec_btn = ui.Button(win, "Decrease Label.width", inc_btn.x+150, inc_btn.y)

local function onClick(self)
	local delta
	if self == inc_btn then
		delta = 10
	else
		delta = -10
	end
	label.width = label.width + delta
end

inc_btn.onClick = onClick
dec_btn.onClick = onClick

-- shows the Window
win:show()

-- update user interface
repeat
	ui.update()
until not win.visible
