Method
GtkSelectionModelset_selection
Declaration [src]
gboolean
gtk_selection_model_set_selection (
GtkSelectionModel* model,
GtkBitset* selected,
GtkBitset* mask
)
Description [src]
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);
mask and selected must not be modified. They may refer to the
same bitset, which would mean that every item in the set should
be selected.
