In glx2 I'm only concerned with undoing changes to the script, and so
I'm storing the htmlText as a single array in a multidimensional
array. Storing the properties could be as easy as adding one more
dimension to the array.
here pObject is the object whose properties you're interested in
and pCount is the undo level (note the propertynames doesn't give you
all the properties, but it's a start):
repeat for each line tProperty in the propertynames
try
-- storing a property value into the array
put the tProperty of pObject into tProp
put tProp into sUndoPointArray[pObject][pCount][pProperty]
-- or retrieving a property value from the array
put sUndoPointArray[pObject][pCount][pProperty] into tProp
catch e
-- in a try/catch because some properties can't be set
end try
end repeat
--
