Question

I am trying to save user s bold/italic/font/etc tags in a GtkTextView. Using GtkTextBuffer.get_text() does not return the tags.

The best documentation I have found on this is: http://www.pygtk.org/docs/pygtk/class-gtktextbuffer.html#method-gtktextbuffer--register-serialize-format

However, I do not understand the function arguments. It would be infinitely handy to have an example of how these are used to save/load a textview with tags in it.

Edit: I would like to clarify what I am trying to accomplish. Basically I want to save/load the textview s text+tags. I have no desire to do anything more complicated than that. I am using pickle as the file format, so I dont need any help here on how to save it or in what format. Just need a way to pull/push the data so that the user loses nothing that he/she sees on screen. Thank you.

Answer 1

If you need to save the tags because you just want to copy the text into another text buffer, you can use gtk.TextBuffer.insert_range().

If you need to save the text with tags into another format readable by other programs, I once wrote a library with a GTK text buffer serializer to and from RTF. It doesn t have any Python bindings though. But in any case the code is a good example of how to use the serializer facility. Link: Osxcart

I haven t worked with GtkTextBuffer s serialization. Reading the documentation you linked, I would suggest trying the default serializer, by calling

textbuffer.register_serialize_tagset()

This gives you GTK+ s built-in proprietary serializer. Being proprietary here means that it doesn t serialize into some well-known format; but if all you need is the ability to save out the text buffer s contents and load them back, this should be fine.

Of course the source code is available inside GTK+ if you really want to figure out how it works; I would recommend against trying to implement e.g. a stand-alone de-serializer though, since there are probably no guarantees made by GTK+ that the format will remain as-is.
