I created an extended editor-snip% class (also using the graph-snip-mixin) and put an instance of this on a pasteboard% (altered via graph-pasteboard-mixin) and then saved the pasteboard to a file.
Reading this file back into the pasteboard fails (no visible errors either). Doing the same with a non-extended editor-snip does work, so the only change is the extension class. >From documentation and looking at the source (in the mred collection) I gather that I need to implement, set and register a custom snip-class% object for my custom editor-snip. Since I am not, at this stage, adding anything to editor-snip% I would like to reuse the editor-snip% write method and the editor-snip-class% read method. Since editor-snip-class% is a private class I do not understand how I can extend it. Is there a way to reuse the editor-snip-class% functionality without cut-and-paste? I notice that editor-snip-class% uses a private top-level var "extended-editor-snip%" to hold the actual class of the snip that it creates. Is there any way to leverage this ? I hope that I missed something obvious - there is a lot of machinery in WXME but nothing that makes this easy. -- Nick
