If this property is set with a line number higher than the last line, the caret stays at the current position.
Edit.line read/write property
Get or set the Edit current line position. The line position starts from 1 and grows until the last line of Edit content.
Setting this property will move the caret position at the start of the line.
Example
local ui = require "ui"
-- create a simple window
local win = ui.Window("Edit.line sample", "fixed", 520, 270)
local edit = ui.Edit(win, "", 10, 10, 500, 230)
-- set edit.properties
edit.font = "Times New Roman"
edit.fontsize = 12
edit.wordwrap = true
edit.text = [[Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
