Example

This example creates a DGS window with a checked and an unchecked combo box and adds a command to toggle their visibility 

DGS = exports.dgs
function drawGUI()
	dgsWindow = DGS:dgsCreateWindow(100,100,200,100,"ComboBox test area",false,false) -- create the container window
	combobox = DGS:dgsCreateComboBox(20,30,150,20,"Checked ComboBox",false,dgsWindow) -- note the parameter after header, it will create a ComboBox
	DGS:dgsComboBoxAddItem(combobox,"Selected") --Add items to combobox
	DGS:dgsComboBoxAddItem(combobox,"UnSelected")
	DGS:dgsComboBoxSetSelectedItem(combobox,1)--set the first row which is the selected row Selected.
	DGS:dgsSetVisible(dgsWindow,false) -- set it invisible just in case
end

addCommandHandler("combobox",function()
	if not dgsWindow then -- if it hasn't been declared yet
		drawGUI() -- we draw the gui window
		DGS:dgsSetVisible(dgsWindow,true) -- we set it visible again. Strictly speaking it's not necessary, could have omitted both this and the upper dgsSetVisible, 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 dgsWindow
		DGS:dgsSetVisible(dgsWindow, not guiGetVisible(dgsWindow)) -- we just toggle the visibility. If it was visible, not visible returns false and thus sets it's visibility false, effectivly hiding it	
	end
	showCursor(not isCursorShowing()) -- similar to above visibility
end)
