	local checkedBox = guiCreateComboBox(20,30,150,20,"Checked ComboBox",true,false,guiWindow) -- note the parameter after header, it will make the ComboBox be checked
	local uncheckedBox = guiCreateComboBox(20,60,150,20,"Unchecked ComboBox",false,false,guiWindow) -- not here though
	guiSetVisible(guiWindow,false) -- set it invisible just in case
end
addCommandHandler("combobox",function()
	if not guiWindow then -- if it hasn't been declared yet
		drawGUI() -- we draw the gui window
		guiSetVisible(guiWindow,true) -- we set it visible again. Strictly speaking it's not necessary, could have omitted both this and the upper guiSetVisible, but this is needed if you want to cache a window without actually showing it
	else -- if we actually have run this function before and declared guiWindow
		guiSetVisible(guiWindow, not guiGetVisible(guiWindow)) -- we just toggle the visibility. If it was visible, not visible returns false and thus sets it's visibility false, effectivly hiding it
