Ho to hide/show GUI window from tray?

[EmptySpace]

How to explain... I want to make GUI to be able to be visible and not visible. Not visible it would be like $oIE = _IECreate("www.google.lt,0,0) <--- these 0 makes it not visible. And it would be controled from tray like making

TrayCreateMenu("Settings")

TrayCreateItem("Display")

TrayCreateItem("Show")

So how I could make it? I should make something with GUISetState?

Ok, GUISetState works. But now other question how to make it to switch after clicking on tray? For example gui is visible and you click directly on tray and then gui hides after clicking second time it shows again?

Something like this:

;Originally written by Zedna
#NoTrayIcon
#include <GuiConstants.au3>
#include <Constants.au3>
#include <WindowsConstants.au3>
Opt("TrayOnEventMode",1)
Opt("TrayMenuMode",1)  
TraySetOnEvent($TRAY_EVENT_PRIMARYUP,"Event")
GuiCreate("MKISH's Example", 392, 316,-1, -1 , BitOR($WS_OVERLAPPEDWINDOW, $WS_CLIPSIBLINGS))
GuiSetState()
While 1
    $msg = GuiGetMsg()
   
    Select
        Case $msg = $GUI_EVENT_MINIMIZE
            GuiSetState(@SW_HIDE)
            TraySetState(1)
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
    EndSelect
WEnd
Func Event()
    GuiSetState(@SW_Show)
    TraySetState(2)
EndFunc
