Hi,
I'm trying to attach extra information to each row in a list, and then retrieve it later on from a row on a double click (row_activated) event.
Basically, i've tried:
g_object_set_data(G_OBJECT(&iter_child), "my_info", GUINT_TO_POINTER(some_info));
This is quite different, bat it should be esealy adapted to your case:
cell = gtk_cell_renderer_toggle_new ();
/* both model pointer and widget reference are sent
* to item-toggled callback function, packed in a
* ModelAndWidget (custom) structure
*/
mw = (ModelAndWidget *)g_malloc (sizeof (ModelAndWidget));
mw->model = model;
mw->widget = drGraph;
g_signal_connect (cell,
"toggled",
G_CALLBACK (on_tvCurves_item_toggled),
mw); col = gtk_tree_view_column_new_with_attributes ("Selection",
cell,
"active",
0,
"activatable",
2,
NULL);
/* adding columns to TreeView
*/
gtk_tree_view_append_column (GTK_TREE_VIEW (treev), col);Information attached to toggles in a treeview are packed into a custom structure and retrievd when they are toggled.
