RE: best way to cutomize gtktextview

[myasar free fr]

I have almost what I want using non-breaking spaces (U+00A0) except that I
forgot an important detail:
I'm using negative indentation (gtk_text_view_set_indent) inside my gtktextview
;-)

So, the following blocks :
_AAA_ A AA A AA A A A_BBB_ B B BB B
_CCC_ C C C CC

are displayed like :
_AAA_ A AA A AA A A A
    _BBB_ B B BB B
_CCC_ C C C CC

instead of :
_AAA_ A AA A AA A A A
_BBB_ B B BB B
_CCC_ C C C CC

Any ideas ?
