Ticked toggle menu item (checkmark?)

I've looked at the GUI tuts and searched this forum, but I can't find a way to add a simple checkmark/tick to a menu item, where you can click on a menu item to turn it on/off like the "Show percentages", "100% panes" in this image.



How would I add that option to a simple menu system and how can I check whether the menu item is checked/unchecked?

I looked at the MaxGUI command Un/CheckMenu, but I'm not sure if this is what I need - or am I wrong? I've tried without success to use it.

Here is a basic framework

Import maxgui.drivers

Global MyWindow:TGadget
Global filemenu:TGadget

MyWindow=CreateWindow("Tick/Check test", 112,84,200,200)

filemenu=CreateMenu("&File",0,WindowMenu(MyWindow))

CreateMenu "New",		101,filemenu
CreateMenu "Open ",	102,filemenu
CreateMenu "AutoSave",	103,filemenu
CreateMenu "Exit",	104,filemenu

UpdateWindowMenu MyWindow

While True
	WaitEvent 
	Select EventID()
		Case EVENT_WINDOWCLOSE
			End
		Case EVENT_MENUACTION
			Select EventData()

                        ' AutoSave
				Case 103
				' Basic tick toggle routine

				' Exit
				Case 104
				 End
				
			End Select
	End Select
Wend

I want the (in this example) "AutoSave" option to be toggled by the user.

You're gonna laugh ;-) because the functions you are looking for are:

CheckMenu(), UncheckMenu() and MenuChecked()

It is worth noting that after calling the first two of the above three, you will need to call UpdateWindowMenu() for the changes to take effect.

I've managed to sort it now. Thanks for the reply. :)
