We could easily make the number of lists and the number of elements in each list totally arbitrary. This would make it easy to let the user define and add a new preset based on what they have currently selected in the 'Destination' frame. I'll look into it when I get a chance. Here is a rough idea using a dictionary whose values are lists.

presets = { 'All On'       : () ,<br></br>          { 'All Off'      : () ,<br></br>          { 'All Toggle'   : () ,<br></br>            'v3 body skin' : ('SkinTorso','SkinNeck','SkinHip','SkinFeet','SkinLeg','SkinArm','SkinHand') ,<br></br>            'v3 skin head' : ('SkinHead','SkinScalp'),<br></br>            'posette bits' : ('nipple','lips')<br></br>          }

then to populate the list box widget,

for ps in presets.keys():<br></br>  self.psetMAT.insert(Tkinter.END, ps)

then to process it, something like this def handleset(self):

for thisPS in self.psetMAT.curselection():

if self.psetMAT.get(thisPS) == 'All On':

self.DstMAT.select_set(0, Tkinter.END)

elif self.psetMAT.get(thisPS) == 'All Off':

self.DstMAT.select_clear()

elif self.psetMAT.get(thisPS) == 'All Toggle':

for thisMATndx in range( self.DstMAT.size() ):

# Some toggle code for each thing

else:

for thisMATndx in range( self.DstMAT.size() ):

if self.DstMAT.get(thisMATndx) in presets[self.psetMAT.get(thisPS)]:

self.DstMAT.select_set(thisMATndx)

I'll check this idea when I get a chance later.
What do you think?
