Trait containing all Selection methods.

NoOpObject, Selection

Required methods

fn add_selection(&self, i: i32) -> bool

Adds the specified accessible child of the object to the object’s selection.

i

a gint specifying the child index.

Returns

TRUE if success, FALSE otherwise.

fn clear_selection(&self) -> bool

Clears the selection in the object so that no children in the object are selected.

Returns

TRUE if success, FALSE otherwise.

fn selection_count(&self) -> i32

Gets the number of accessible children currently selected. Note: callers should not rely on None or on a zero value for indication of whether AtkSelectionIface is implemented, they should use type checking/interface checking macros or the atk_get_accessible_value() convenience method.

Returns

a gint representing the number of items selected, or 0 if self does not implement this interface.

fn is_child_selected(&self, i: i32) -> bool

Determines if the current child of this object is selected Note: callers should not rely on None or on a zero value for indication of whether AtkSelectionIface is implemented, they should use type checking/interface checking macros or the atk_get_accessible_value() convenience method.

i

a gint specifying the child index.

Returns

a gboolean representing the specified child is selected, or 0 if self does not implement this interface.

fn ref_selection(&self, i: i32) -> Option<Object>

Gets a reference to the accessible object representing the specified selected child of the object. Note: callers should not rely on None or on a zero value for indication of whether AtkSelectionIface is implemented, they should use type checking/interface checking macros or the atk_get_accessible_value() convenience method.

i

a gint specifying the index in the selection set. (e.g. the ith selection as opposed to the ith child).

Returns

an Object representing the selected accessible, or None if self does not implement this interface.

fn remove_selection(&self, i: i32) -> bool

Removes the specified child of the object from the object’s selection.

i

a gint specifying the index in the selection set. (e.g. the ith selection as opposed to the ith child).

Returns

TRUE if success, FALSE otherwise.

fn select_all_selection(&self) -> bool

Causes every child of the object to be selected if the object supports multiple selections.

Returns

TRUE if success, FALSE otherwise.

fn connect_selection_changed<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The “selection-changed” signal is emitted by an object which implements AtkSelection interface when the selection changes.
