Coding Colleagues...

Does anyone know if there's some code out there that I can bolt onto a GtkTextView to enable formatted save and load? XML would be nice, ODT even better, even RTF (Save) would do. It would save me the arduous task of re-inventing the wheel!

Hello.

Formated save and load are called serializing and deserializing a text buffer. Unfortunately, there is no predefined (de)serialize functions for XML, ODT or RTF (there is an internal format called "tagset", which is able to save text and pixbufs into XML-ish format, but it's only useful if you only intend to save/load files from your application).

One problem with creating XML export is the fact that XML only holds references to images while GtkTextBuffer doesn't hold any information where source image for pixbuf came from and how it has been transformed (stretched, rotated ...). But if your data doesn't contain images, things should be pretty straight forward to implement.

See tagset serialization functions that come with gtk for inspiration: http://git.gnome.org/cgit/gtk+/tree/gtk/gtktextbufferserialize.c.

Hope this information helps.

Excellent, I'll follow-up these leads.

Thanks for the pointers. Y'know, sometimes I wonder if the Gtk docs are written in English or Gnomish. The number of times that I've scanned those pages and not picked up the implications!

Well, its done now and Gnocl has rich text load/save as well as the plain old text.

Ta ever so...

Following up on this rather old thread.

There is a module which will serialize/deserialize a GtkTextBuffer into rtf format.
