Problems using GtkTreeView and making stuff editable

[Philip Van Hoof <spamfrommailing freax org>]

Hi there,

I want to create a GtkTreeView widget with two editable textcolumns
All seems to work and the textfields are editable but when I edit them
and then press 'enter' or 'tab' then the original text is back in
place (so I can edit it, but after editing all changes are discarded).

What am I doing wrong? :-\



enum
{
   TARGET_COLUMN,
   MAXSIZE_COLUMN,
   N_COLUMNS
};


pwin->tarstore = gtk_tree_store_new (N_COLUMNS, G_TYPE_STRING,
G_TYPE_INT);


  pwin->tartreeview = gtk_tree_view_new_with_model
(GTK_TREE_MODEL(pwin->tarstore));

  pwin->tartargetcolumn = gtk_tree_view_column_new();
  pwin->text1cell = gtk_cell_renderer_text_new ();
  gtk_tree_view_column_set_title (pwin->tartargetcolumn, _("Target"));
  gtk_tree_view_column_pack_start(pwin->tartargetcolumn,
pwin->text1cell, TRUE);
  gtk_tree_view_column_set_attributes(pwin->tartargetcolumn,
pwin->text1cell,
         "text", TARGET_COLUMN, "editable", TRUE, NULL);


  pwin->tarmaxsizecolumn = gtk_tree_view_column_new();
  pwin->text2cell = gtk_cell_renderer_text_new ();
  gtk_tree_view_column_set_title (pwin->tarmaxsizecolumn, _("Max.
Length"));
  gtk_tree_view_column_pack_start(pwin->tarmaxsizecolumn,
pwin->text2cell, TRUE);
  gtk_tree_view_column_set_attributes(pwin->tarmaxsizecolumn,
pwin->text2cell,
          "text", MAXSIZE_COLUMN,"editable", TRUE, NULL);


gtk_tree_view_append_column (GTK_TREE_VIEW (pwin->tartreeview),
pwin->tartargetcolumn);
  gtk_tree_view_append_column (GTK_TREE_VIEW (pwin->tartreeview),
pwin->tarmaxsizecolumn);
