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.

Checks whether the specified point is within the extent of the component.

Returns the alpha value (i.e. the opacity) for this component, on a scale from 0 (fully transparent) to 1.0 (fully opaque).

Gets the rectangle which gives the extent of the component.

Gets the layer of the 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.

Gets the position of component in the form of a point specifying component‘s top-left corner.

Gets the size of the component in terms of width and height.

Grabs focus for this component.

Gets a reference to the accessible child, if one exists, at the coordinate point specified by x and y.

Remove the handler specified by handler_id from the list of functions to be executed when this object receives focus events (in or out).

Makes component visible on the screen by scrolling all necessary parents.

Move the top-left of component to a given position of the screen by scrolling all necessary parents.

Sets the extents of component.

Sets the position of component.

Set the size of the component in terms of width and height.

Gets the value of this object.

Gets the minimum increment by which the value of this object may be changed. If zero, the minimum increment is undefined, which may mean that it is limited only by the floating point precision of the platform.

Gets the maximum value of this object.

Gets the minimum increment by which the value of this object may be changed. If zero, the minimum increment is undefined, which may mean that it is limited only by the floating point precision of the platform.

Gets the minimum value of this object.

Gets the range of this object.

Gets the list of subranges defined for this object. See AtkValue introduction for examples of subranges and when to expose them.

Gets the current value and the human readable text alternative of obj. text is a newly created string, that must be freed by the caller. Can be NULL if no descriptor is available.

Sets the value of this object.

Sets the value of this object.

Table caption.

Accessible table column description.

Accessible table column header.

Accessible table row description.

Accessible table row header.

Numeric value of this object, in case being and AtkValue.

The “active-descendant-changed” signal is emitted by an object which has the state ATK_STATE_MANAGES_DESCENDANTS when the focus object in the object changes. For instance, a table will emit the signal when the cell in the table which has focus changes.

The “announcement” signal can be emitted to pass an announcement on to be read by a screen reader.

The signal “children-changed” is emitted when a child is added or removed form an object. It supports two details: “add” and “remove”.

The signal “focus-event” is emitted when an object gained or lost focus.

The “notification” signal can be emitted to pass an announcement on to be read by a screen reader.

The signal “property-change” is emitted when an object’s property value changes. arg1 contains an AtkPropertyValues with the name and the new value of the property whose value has changed. Note that, as with GObject notify, getting this signal does not guarantee that the value of the property has actually changed; it may also be emitted when the setter of the property is called to reinstate the previous value.

The “state-change” signal is emitted when an object’s state changes. The detail value identifies the state type which has changed.

The “visible-data-changed” signal is emitted when the visual appearance of the object changed.

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

The ‘bounds-changed” signal is emitted when the bposition or size of the component changes.

The ‘value-changed’ signal is emitted when the current value that represent the object changes. value is the numerical representation of this new value. text is the human readable text alternative of value, and can be NULL if it is not available. Note that if there is a textual description associated with the new numeric value, that description should be included regardless of whether or not it has also changed.
