mmmmm but do you want also to serialize external handles ? what are you going to do with them when you load the objects again to memory ?
That was my point exactly, read Object>storeOn: (which Fonts currently use), I thought Steph's suggestion was to use that method to serialize fonts. However, I think I misunderstood, and Steph meant to write the logic for storing attributes you'd need to rebuild a Font instance in store/writeOn: and readFrom: methods. (storeOn: is usually reserved for writing an executable expression which will yield the instance, so it's probably a bad idea to use it paired with readFrom:) Which is an option of course, but the usual convention in image readFrom: methods seem to be having them instance-side. That wouldn't make sense if you want to return an already-existing, closest fitting to the saved attributes, Font instance. Cheers, Henry
For StrikeFonts, it may, but even if it did, you'd probably end up importing a new Font instance (complete with an XX KB bitmap), for each Morph...
Cheers, Henry
