# Atk::Selection Class Reference

Inheritance diagram for Atk::Selection:

[legend]
List of all members.

## 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.

## Public Member Functions

## Member Function Documentation

static void Atk::Selection::add_interface | ( | GType | gtype_implementer | ) | `[static]`

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.

virtual bool Atk::Selection::add_selection_vfunc | ( | int | i | ) | `[protected, virtual]`

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.

virtual bool Atk::Selection::clear_selection_vfunc | ( |  | ) | `[protected, virtual]`

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.

virtual Glib::RefPtr<Atk::Object> Atk::Selection::get_selection_vfunc | ( | int | i | ) | `[protected, virtual]`

const AtkSelection* Atk::Selection::gobj | ( |  | ) | const`[inline]`

Reimplemented from Glib::Interface.

Reimplemented in Atk::NoOpObject.

AtkSelection* Atk::Selection::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Atk::NoOpObject.

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.

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.

virtual bool Atk::Selection::remove_selection_vfunc | ( | int | i | ) | `[protected, virtual]`

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