[maemo-developers] how to adjust padding of HildonTouchSelectorColumn's private panarea?

[From: kyle cronan]

Hi everyone,

It looks like the hildon_touch_selector_append_column function has a
hard-coded padding of 6 pixels around the column's panarea, which gets
added to the selector's internal hbox widget.  Is there any way I
could override this without pulling private structure definitions out
of the libhildon code?  Media player managed to do it somehow: the
selector entries go all the way to the edges of the screen and it
looks really nice.

Thanks,
Kyle
