You can use the SingleLayout of my GeometryManager ([Login to see the link]).
local ui = require("ui")
require "webview"
local gm = require("ecluart.gm")
local win = ui.Window("SingelLayout", 600, 400)
win:status("https://www.luart.org")
local single = gm.GeometryManager():SingleLayout(win, gm.RESIZE.Both, 0, 0, 600, 377)
local view = ui.Webview(win, "https://www.luart.org")
single:add(view)
function win:onResize()
single:update()
end
single:apply()
win:show()
repeat
ui.update()
until not win.visible
If you rize the window the WebView will be placed that to statusbar is allways visible.
