Constants |
NAME_CHANGED |
Use this event type to indicate a change of the name string
of an accessible object. The
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields contain the
name before and after the change.
|
DESCRIPTION_CHANGED |
Use this event type to indicate a change of the description string
of an accessible object. The
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields contain the
description before and after the change.
|
ACTION_CHANGED |
The change of the number or attributes of actions of an accessible
object is signaled by events of this type.
|
STATE_CHANGED |
State changes are signaled with this event type. Use one event for
every state that is set or reset. The
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields contain the
old and new value respectively. To set a state put the state id
into the AccessibleEventObject::NewValue field and
leave AccessibleEventObject::OldValue empty. To
reset a state put the state id into the
AccessibleEventObject::OldValue field and leave
AccessibleEventObject::NewValue empty.
|
ACTIVE_DESCENDANT_CHANGED |
Constant used to determine when the active descendant of a component
has changed. The active descendant is used in objects with
transient children. The AccessibleEventObject::NewValue
contains the now active object. The
AccessibleEventObject::OldValue contains the
previously active child. Empty references indicate that no child
has been respectively is currently active.
|
BOUNDRECT_CHANGED |
This event indicates a change of the bounding rectangle of an
accessible object with respect only to its size or relative
position. If the absolute position changes but not the relative
position then its is not necessary to send an event.
|
CHILD |
A child event indicates the addition of a new or the removal of an
existing child. The contents of the
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields determines
which of both has taken place.
|
INVALIDATE_ALL_CHILDREN |
Use this event to tell the listeners to re-retrieve the whole set of
children. This should be used by a parent object which exchanges all
or most of its children. It is a short form of first sending one
CHILD event for every old child indicating that
this child is about to be removed and then sending one
CHILD for every new child indicating that this
child has been added to the list of children.
|
SELECTION_CHANGED |
Events of this type indicate changes of the selection. The
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields remain empty.

|
VALUE_CHANGED |
This constant indicates changes of the value of an
XAccessibleValue interface. The
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue field contain the
old and new value as a number. Its exact type is implementation
dependant but has to be the same as is returned by the
XAccessibleValue::getCurrentValue function.
|
CONTENT_FLOWS_FROM_RELATION_CHANGED |
Identifies the change of a relation set: The content flow has
changed. The AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields contain

AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields.
|
TEXT_SELECTION_CHANGED |
Events of this type signal changes of the selection. The old or new
selection is not available through the event object. You
have to query the XAccessibleText interface of the

AccessibleEventObject::NewValue fields contain the
name before and after the change.
|
|
DESCRIPTION_CHANGED
const short DESCRIPTION_CHANGED = 2;
- Description
- Use this event type to indicate a change of the description string
of an accessible object. The
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields contain the
description before and after the change.
|
|
ACTION_CHANGED
const short ACTION_CHANGED = 3;
- Description
- The change of the number or attributes of actions of an accessible
object is signaled by events of this type.
The AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields contain the
old and new number of actions.
|
|
STATE_CHANGED
const short STATE_CHANGED = 4;
- Description
- State changes are signaled with this event type. Use one event for
every state that is set or reset. The
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields contain the
old and new value respectively. To set a state put the state id
into the AccessibleEventObject::NewValue field and
leave AccessibleEventObject::OldValue empty. To
reset a state put the state id into the
AccessibleEventObject::OldValue field and leave
AccessibleEventObject::NewValue empty.
|
|
ACTIVE_DESCENDANT_CHANGED
const short ACTIVE_DESCENDANT_CHANGED = 5;
- Description
- Constant used to determine when the active descendant of a component
has changed. The active descendant is used in objects with
transient children. The AccessibleEventObject::NewValue
contains the now active object. The
AccessibleEventObject::OldValue contains the
previously active child. Empty references indicate that no child
has been respectively is currently active.
|
|
BOUNDRECT_CHANGED
const short BOUNDRECT_CHANGED = 6;
- Description
- This event indicates a change of the bounding rectangle of an
accessible object with respect only to its size or relative
position. If the absolute position changes but not the relative
position then its is not necessary to send an event.
Use this event rather than the
VISIBLE_DATA_EVENT when really only the
(relative) bounding box of an accessible object has changed. It is
much more specific than the later one and reduces the number of
calls an AT-Tool has to make to retrieve all affected data.
The AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue remain empty. Use
a call to the XAccessibleComponent::getBounds()
method to determine the new bounding box.
|
|
CHILD
const short CHILD = 7;
- Description
- A child event indicates the addition of a new or the removal of an
existing child. The contents of the
AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue fields determines

If a new child has been added then
the AccessibleEventObject::NewValue contains a
reference to this new object and
AccessibleEventObject::OldValue remains empty.
If a child has been removed then the
AccessibleEventObject::OldValue contains a
reference to this object and
AccessibleEventObject::NewValue remains empty.
If a child has been added and a another one has been removed
don't set both fields at the same. Send separate events
instead.
Note that a child event is sent after a child has been added or
removed. Especially in the case of a removal this means that the
removed object does not have a parent anymore.
|
|
INVALIDATE_ALL_CHILDREN
const short INVALIDATE_ALL_CHILDREN = 8;
- Description
- Use this event to tell the listeners to re-retrieve the whole set of
children. This should be used by a parent object which exchanges all
or most of its children. It is a short form of first sending one
CHILD event for every old child indicating that
this child is about to be removed and then sending one
CHILD for every new child indicating that this
child has been added to the list of children.
When this API is used by Java or Gnome AT-Tools then a bridge can
generate the events described above automatically.

that is exposed through the XAccessibleText and
XAccessibleEditableText interfaces.
The affected text ranges are represented by TextSegment structures.
The content of the AccessibleEventObject::OldValue and
AccessibleEventObject::NewValue expresses the type
of text change: - Insertion: the
AccessibleEventObject::NewValue field specifies the
inserted text after the insertion, the
AccessibleEventObject::OldValue field remains
empty.
- Deletion: the
AccessibleEventObject::OldValue field specifies the
deleted text before the deletion, the
AccessibleEventObject::NewValue field remains
empty.
- Update/Replace/Modification: the
AccessibleEventObject::OldValue and

modified text before respectively after the modification.
- Unknown: when the type of text change or the place where it took
place can not be determined by the event broadcaster then both
fields remain empty. In this case the whole text may have changed
and the listener should refetch the text completely.
When broadcasting an event allways prefer the first three cases
to the last one. Use it only as a last resort.
Text ranges should be as small as possible but, of course,
include all the text that is involved in a modification. That means
that when two or more discontiguous text ranges are inserted,
deleted, or otherwise modified the two fields of the event have to
cover all the effected text ranges as well as the text in
between.
