## Detailed Description

The ATK interface implemented by container objects whose Atk::Object children can be selected.

This should be implemented by UI components with children which are exposed by Atk::Object::ref_child and Atk::Object::get_n_children, if the use of the parent UI component ordinarily involves selection of one or more of the objects corresponding to those AtkObject children - for example, selectable lists.

Note that other types of "selection" (for instance text selection) are accomplished a other ATK interfaces - Atk::Selection is limited to the selection/deselection of children.

## Member Function Documentation

bool Atk::Selection::add_selection | ( | int | i | ) |

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

Parameters:

  i | A `int` specifying the child index.

Returns:
  `true` if success, `false` otherwise.

bool Atk::Selection::clear_selection | ( |  | ) |

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

Returns:
  `true` if success, `false` otherwise.

Glib::RefPtr<Atk::Object> Atk::Selection::get_selection | ( | int | i | ) |

Gets a reference to the accessible object representing the specified selected child of the object.

Note:
  callers should not rely on `0` 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.

Parameters:

  i | A `int` specifying the index in the selection set. (e.g. the ith selection as opposed to the ith child).

Returns:
  An Atk::Object representing the selected accessible , or `0` if selection does not implement this interface.

int Atk::Selection::get_selection_count | ( |  | ) | const

Gets the number of accessible children currently selected.

Note:
  callers should not rely on `0` 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 `int` representing the number of items selected, or 0 if selection does not implement this interface.

bool Atk::Selection::is_child_selected | ( | int | i | ) | const

Determines if the current child of this object is selected.

Note:
  callers should not rely on `0` 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.

Parameters:

  i | A `int` specifying the child index.

Returns:
  A `bool` representing the specified child is selected, or 0 if selection does not implement this interface.

bool Atk::Selection::remove_selection | ( | int | i | ) |

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

Parameters:

  i | A `int` specifying the index in the selection set. (e.g. the ith selection as opposed to the ith child).

Returns:
  `true` if success, `false` otherwise.

bool Atk::Selection::select_all_selection | ( |  | ) |

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

Returns:
  `true` if success, `false` otherwise.

Glib::SignalProxy0< void > Atk::Selection::signal_selection_changed | ( |  | ) |

Prototype:
  `void on_my_selection_changed()`

## Friends And Related Function Documentation

Glib::RefPtr< Atk::Selection > wrap | ( | AtkSelection * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
