Virtually all widgets will need to have AtkComponent implementations provided for their corresponding AtkObject class. In short, only UI elements which are *not* GUI elements will omit this ATK interface. A possible exception might be textual information with a transparent background, in which case text glyph bounding box information is provided by AtkText. DetailsAtkComponenttypedef struct _AtkComponent AtkComponent; The AtkComponent structure does not contain any fields. atk_component_add_focus_handler ()guint atk_component_add_focus_handler (AtkComponent *component, AtkFocusHandler handler); Add the specified handler to the set of functions to be called when this object receives focus events (in or out). If the handler is already added it is not added again
atk_component_contains ()gboolean atk_component_contains (AtkComponent *component, gint x, gint y, AtkCoordType coord_type);
Checks whether the specified point is within the extent of the
atk_component_get_extents ()void atk_component_get_extents (AtkComponent *component, gint *x, gint *y, gint *width, gint *height, AtkCoordType coord_type);
Gets the rectangle which gives the extent of the
atk_component_get_layer ()AtkLayer atk_component_get_layer (AtkComponent *component); Gets the layer of the component.
atk_component_get_mdi_zorder ()gint atk_component_get_mdi_zorder (AtkComponent *component); Gets the zorder of the component. The value G_MININT will be returned if the layer of the component is not ATK_LAYER_MDI or ATK_LAYER_WINDOW.
atk_component_get_position ()void atk_component_get_position (AtkComponent *component, gint *x, gint *y, AtkCoordType coord_type);
Gets the position of
atk_component_get_size ()void atk_component_get_size (AtkComponent *component, gint *width, gint *height);
Gets the size of the
atk_component_grab_focus ()gboolean atk_component_grab_focus (AtkComponent *component);
Grabs focus for this
atk_component_ref_accessible_at_point ()AtkObject* atk_component_ref_accessible_at_point (AtkComponent *component, gint x, gint y, AtkCoordType coord_type);
Gets a reference to the accessible child, if one exists, at the
coordinate point specified by
atk_component_remove_focus_handler ()void atk_component_remove_focus_handler (AtkComponent *component, guint handler_id);
Remove the handler specified by
atk_component_set_extents ()gboolean atk_component_set_extents (AtkComponent *component, gint x, gint y, gint width, gint height, AtkCoordType coord_type);
Sets the extents of
atk_component_set_position ()gboolean atk_component_set_position (AtkComponent *component, gint x, gint y, AtkCoordType coord_type);
Sets the postition of
atk_component_set_size ()gboolean atk_component_set_size (AtkComponent *component, gint width, gint height);
Set the size of the
atk_component_get_alpha ()gdouble atk_component_get_alpha (AtkComponent *component);
Returns the alpha value (i.e. the opacity) for this
