Re: [Glade-users] GtkListStore. (Multiple selection)

[Harring Figueiredo <harringf yahoo com>]

    Thanks for the suggestion. Dave dave<at>gurumeditation.it provided me with
a simple/good example.
     My problem is that, when using *foreach(); we cannot delete any rows
because the remove() messes up the iter on the store/model. Thus cuases some
rows to not be deleted and sometimes gives some ugly  error messages.
     I am trying to think of a way to mark the selectect rows -- and I guess I
found a obscure way that works: Add a non-visible flag on the model, and on the
foreach function, I set it to true (meaning it was selected -- after the
foreach call is done, I loop through the model and remove the rows I had set.

  Ugly, but it should work.

  Thank for the reply.

Harring.
