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

Progressbar.width read/write property

Example


local ui = require "ui"

-- create a simple Window
local win = ui.Window("Progressbar.width sample", 360, 200)
local pb = ui.Progressbar(win, 50)
local inc_btn = ui.Button(win, "Increase Progressbar.width !", 15, 50)
local dec_btn = ui.Button(win, "Decrease Progressbar.width", inc_btn.x+inc_btn.width+10, inc_btn.y)

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