setSelection

Make selection changes.

This is the most advanced selection updating method that allows the most fine-grained control over selection changes. If you can, you should try the simpler versions, as implementations are more likely to implement support for those.

Requests that the selection state of all positions set in @mask be updated to the respective value in the @selected bitmask.

In pseudocode, it would look something like this:

for (i = 0; i < n_items; i++)
  {
    // don't change values not in the mask
    if (!gtk_bitset_contains (mask, i))
      continue;

    if (gtk_bitset_contains (selected, i))
      select_item (i);
    else
      unselect_item (i);
  }

gtk_selection_model_selection_changed (model,
                                       first_changed_item,
                                       n_changed_items);
