I have a question regarding the MultiChoiceProperty which I hope you can help with. I have PropertyGrid with two properties 1) EnumProperty and 2) MultiChoiceProperty (MCP). I bind to the EVT_PG_CHANGED event. What I would like to happen is that when a new item is selected in the EnumProperty I would like to change the list of choices displayed in the MultiChoiceProperty and have those new choices in the 'selected state' i.e. so that they appear in the property grid as items which have been selected.
As I mention I handle EVT_PG_CHANGED event...in this event handler I am able to successfully change the 'choices' of the MCP in response to a change in the EnumProperty selection but am unable to set the state of the 'new choices' of the MCP to 'selected'. I had thought .SetChoiceSelection() method of MCP would work but it doesn't seem to do anything (selection state is unchanged after the call and items do not appear in ProperyGrid and only seems to take a single integer as parameter whereas for multi select I would have thought a list would have been required.
My code looks like this (see attached also). I question therefore is...is this the correct method or is there an alternative ? I'm running on a Windows7 laptop with wxPython 4.0.0a1 , Python 3
Any thoughts would be appreciated.

#The following statements doesn't seem to do anything
#ideally I want all the new_values to be set to the "selected"
#state and appear as a list of items in the property grid
#at the moment despite this call the text displayed
#in the propperty grid for this item is blank
#and when you click on the button of the MultiChoiceProperty
#the new items are also not selected. How to set the new items
#to the selected state and have them appear in the text field of
#the property grid corresponding to the MultiChoiceProperty?
