Re: gtktextview with gdkpixbuf saving into file

[Johnson Wong <jjwh tpg com au>]

solved the issue by scanning the textbuffer for pixbufs and replace them
with tags. so loading the file into a textbuffer/textview then simply
means parsing the tags and load pixbuf on the go.

text text text
..
<img=pixbuf>
..
text text text

if there is a better way to do save/load on textview with embeeded
pixbuf, please let me know.

cheers
Johnson
