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

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 )

protectedvirtual

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 ( )

protectedvirtual

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.

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.

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

virtual Glib::RefPtr<Atk::Object> Atk::Selection::get_selection_vfunc ( int  i )

protectedvirtual

static GType Atk::Selection::get_type ( )

static

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

AtkSelection* Atk::Selection::gobj ( )

inline

Provides access to the underlying C GObject.

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

inline

Provides access to the underlying C GObject.

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.

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

protectedvirtual

virtual void Atk::Selection::on_selection_changed ( )

protectedvirtual

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

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

noexcept

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.

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

protectedvirtual

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.

virtual bool Atk::Selection::select_all_selection_vfunc ( )

protectedvirtual

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.
