Tab.width read/write property
Get or set the Tab width. The width starts from 0 (left side of the Tab) and increases to the right direction.
Example
local ui = require "ui"
-- create a simple Window
local win = ui.Window("Tab.width sample", 640, 300)
local tab = ui.Tab(win, {"Item 1", "Item 2"})
local inc_btn = ui.Button(win, "Increase Tab.width", 200, 260)
local dec_btn = ui.Button(win, "Decrease Tab.width", inc_btn.x+inc_btn.width+6, inc_btn.y)
inc_btn.delta = 10
dec_btn.delta = -10
local function onClick(self)
tab.width = tab.width + self.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
