Hide TopMenu on login screen [OTClient]

[Helliot1]

How it's in the title I would like to know how to hide the topmenu in the login screen. But when I'm online, the topmenu appear?

I know it's a very simple code, but I don't understand about Lua.
I tried somethings but didn't work.

Can anybody help me?
Thank you

Topmenu.Lua

-- private variables
local topMenu
local leftButtonsPanel
local rightButtonsPanel
local leftGameButtonsPanel
local rightGameButtonsPanel

-- private functions
local function addButton(id, description, icon, callback, panel, toggle, front)
  local class
  if toggle then
    class = 'TopToggleButton'
  else
    class = 'TopButton'
  end

  local button = panel:getChildById(id)
  if not button then
    button = g_ui.createWidget(class)
    if front then
      panel:insertChild(1, button)
    else
      panel:addChild(button)
    end
  end
  button:setId(id)
  button:setTooltip(description)
  button:setIcon(resolvepath(icon, 3))
  button.onMouseRelease = function(widget, mousePos, mouseButton)
    if widget:containsPoint(mousePos) and mouseButton ~= MouseMidButton then
      callback()
      return true
    end
  end
  return button

Easy, add this to hide top menu:

modules.client_topmenu.getTopMenu():setHeight(0)

And this when you want to switch ON top menu:

modules.client_topmenu.getTopMenu():setHeight(36)

Where?
I advise you to add to client_background -> background.lua
Functions:
hide()
show()

[Full solution] Change background.lua to this:

-- private variables
local background
local clientVersionLabel

-- public functions
function init()
  background = g_ui.displayUI('background')
  background:lower()

  clientVersionLabel = background:getChildById('clientVersionLabel')
  clientVersionLabel:setText(g_app.getName() .. ' ' .. g_app.getVersion() .. '\n' ..
                             'Rev  ' .. g_app.getBuildRevision() .. ' ('.. g_app.getBuildCommit() .. ')\n' ..
                             'Built on ' .. g_app.getBuildDate() .. '\n' .. g_app.getBuildCompiler())

  if not g_game.isOnline() then
    addEvent(function() g_effects.fadeIn(clientVersionLabel, 1500) end)
  end

  connect(g_game, { onGameStart = hide })
  connect(g_game, { onGameEnd = show })
  modules.client_topmenu.getTopMenu():setHeight(0)
end

function terminate()
  disconnect(g_game, { onGameStart = hide })
  disconnect(g_game, { onGameEnd = show })

  g_effects.cancelFade(background:getChildById('clientVersionLabel'))
  background:destroy()

  Background = nil
end

function hide()
  background:hide()
  modules.client_topmenu.getTopMenu():setHeight(36)
end

function show()
  background:show()
  modules.client_topmenu.getTopMenu():setHeight(0)
end

function hideVersionLabel()
  background:getChildById('clientVersionLabel'):hide()
end

function setVersionText(text)
  clientVersionLabel:setText(text)
end

function getBackground()
  return background
end

MagicWall, you are awesome!!

You taught me how to do it too, it's completely different from what I was doing.

Thanks!!
