## 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.

## Constructor & Destructor Documentation

## ◆ Selection() [1/2]

Atk::Selection::Selection | ( |  | ) |
| protected

You should derive from this class to use it.

## ◆ Selection() [2/2]

Atk::Selection::Selection | ( | Selection && | src | ) |
| noexcept

## ◆ ~Selection()

Atk::Selection::~Selection | ( |  | ) |
| overridenoexcept

## Member Function Documentation

## ◆ add_interface()

void Atk::Selection::add_interface | ( | GType | gtype_implementer | ) |
| static

## ◆ add_selection()

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.

## ◆ add_selection_vfunc()

virtual bool Atk::Selection::add_selection_vfunc | ( | int | i | ) |
| protectedvirtual

## ◆ clear_selection()

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.

## ◆ clear_selection_vfunc()

virtual bool Atk::Selection::clear_selection_vfunc | ( |  | ) |
| protectedvirtual

## ◆ get_selection()

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 nullptr 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 nullptr if selection does not implement this interface.

## ◆ get_selection_count()

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

Gets the number of accessible children currently selected.

Note
  callers should not rely on nullptr 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.

## ◆ get_selection_count_vfunc()

virtual int Atk::Selection::get_selection_count_vfunc | ( |  | ) | const
| protectedvirtual

## ◆ get_selection_vfunc()

## ◆ get_type()

GType Atk::Selection::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

## ◆ gobj() [1/2]

AtkSelection * Atk::Selection::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

## ◆ gobj() [2/2]

const AtkSelection * Atk::Selection::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

## ◆ is_child_selected()

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 nullptr 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.

## ◆ is_child_selected_vfunc()

virtual bool Atk::Selection::is_child_selected_vfunc | ( | int | i | ) | const
| protectedvirtual

## ◆ on_selection_changed()

virtual void Atk::Selection::on_selection_changed | ( |  | ) |
| protectedvirtual

This is a default handler for the signal signal_selection_changed().

## ◆ operator=()

Selection & Atk::Selection::operator= | ( | Selection && | src | ) |
| noexcept

## ◆ remove_selection()

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

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

Parameters

Returns
  true if success, false otherwise.

virtual bool Atk::Selection::remove_selection_vfunc | ( | int | i | ) |
| protectedvirtual

## ◆ select_all_selection()

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.

## ◆ select_all_selection_vfunc()

virtual bool Atk::Selection::select_all_selection_vfunc | ( |  | ) |
| protectedvirtual

## ◆ signal_selection_changed()

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

Slot Prototype:
  void on_my_selection_changed()

Flags: Run Last

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

## Friends And Related Symbol Documentation

## ◆ wrap()

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.
