I don't know if i can directly place user-editable numeric values into
treeview, instead of strings, it's possible? This is due to absence of
examples: all treeview's C code samples found (with user-editing) are
text/string. But also it's due to probably in future, user input can be
in form '50 mil' or '2e3 mkm', i don't know useful it or no, but
currently it can be easy added.

It can work only in my dreams, because currently i even don't know how to
write gtk callback procedure header...:(
Example:
I need to write "Set by Mark Distance" button press procedure (as you
see, currently tied to dummy write (and it work well :D ) )
I copypaste your new cb_edited_mm_or_mil proc, because *it has access to
treeview items* and contains all i need; only small modifications need.
I don't touch the header because i don't know how to rewrite it correctly:
/(GtkCellRendererText *cell,
gchar *path,
gchar *text,
GtkTreeView *treeview)/
but it tied not here
/ g_signal_connect(renderer, "edited", (GCallback) cb_edited_mm_or_mil,
treeview);/
but i place it here :
/ ghid_button_connected (hbox_btn_grids, NULL, FALSE, FALSE, FALSE, 4,
cb_grid_setbymarkdistance, NULL, _("Set by Mark Distance"), ....../
and it of course not work: program crashes silently, no any debug info,
no way to read anything or things how to rewrite the header, no suitable
examples... compiles without warnings.

Is there any success-story about it or example using docs IRL ?
Thanks! :)
