AtkSelectionAtkSelection — The ATK interface implemented by container objects whose AtkObject children can be selected. |

AtkSelection 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 - AtkSelection is limited to the selection/deselection of children.
gboolean atk_selection_add_selection (AtkSelection *selection,gint i);
Adds the specified accessible child of the object to the object's selection.
gboolean
atk_selection_clear_selection (AtkSelection *selection);
Clears the selection in the object so that no children in the object are selected.
AtkObject * atk_selection_ref_selection (AtkSelection *selection,gint i);
Gets a reference to the accessible object representing the specified
selected child of the object.
Note: callers should not rely on NULL 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.
selection |
a GObject instance that implements AtkSelectionIface |
|
i |
a gint specifying the index in the selection set. (e.g. the ith selection as opposed to the ith child). |
an AtkObject representing the
selected accessible, or NULL if selection
does not implement this
interface.
[nullable][transfer full]
gint
atk_selection_get_selection_count (AtkSelection *selection);
Gets the number of accessible children currently selected.
Note: callers should not rely on NULL 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.
gboolean atk_selection_is_child_selected (AtkSelection *selection,gint i);
Determines if the current child of this object is selected
Note: callers should not rely on NULL 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.
gboolean atk_selection_remove_selection (AtkSelection *selection,gint i);
Removes the specified child of the object from the object's selection.
gboolean
atk_selection_select_all_selection (AtkSelection *selection);
Causes every child of the object to be selected if the object supports multiple selections.
“selection-changed” signalvoid user_function (AtkSelection *atkselection, gpointer user_data)
The "selection-changed" signal is emitted by an object which implements AtkSelection interface when the selection changes.
atkselection |
the object which received the signal. |
|
user_data |
user data set when the signal handler was connected. |
