Dropdown List for Symbols?

[willofmaine]

The "Get Texture" node creates a dropdown list in the OIP for selecting textures.  Is there not a similar node to create a dropdown list in the OIP for selecting symbols?...  If not, it sure would be very helpful!!

@Marionette.NodeDefinition
class Params(metaclass = Marionette.OrderedClass):
	
	def get_SymDefs_in_File ():
		'''
			Returns all Symbol-Definitions as list found in the active Document.
		'''
		
		syms = []	
		
		SYMBOL_DEFINI_TYPE = 16	
		 
		CURRENT_DOC = 0 
		Res_List, NumItems = vs.BuildResourceList (SYMBOL_DEFINI_TYPE, CURRENT_DOC, '')
		
		for i in range (NumItems):
			# Die Resourcelist beginnt nicht wie üblich mit dem Index 0 sondern mit 1 
			i += 1
			
			h = vs.GetResourceFromList (Res_List, i)		   
			
			syms.append ( vs.GetName(h))
		
		return syms
	###

	this = Marionette.Node( 'Get Sym' )
	
	sym_list = get_SymDefs_in_File ()
	
	sym_popUp = Marionette.OIPControl( 'Syms', Marionette.WidgetType.Popup, 0, sym_list)
	
	sym = Marionette.PortOut()   
	
	
def RunNode(self):
	sel_idx = self.Params.sym_popUp.value
	self.Params.sym.value = self.Params.sym_popUp.popupChoices[sel_idx]

 

Unfortunately you have to run it to refresh the popup values.
