 org.eclipse.swt.accessibility.AccessibleAdapter
| AccessibleAdapter | | abstract public class AccessibleAdapter implements AccessibleListener(Code) | | This adapter class provides default implementations for the
methods described by the AccessibleListener interface.
Classes that wish to deal with AccessibleEvents can
extend this class and override only the methods that they are
interested in.
Note: Accessibility clients use child identifiers to specify
whether they want information about a control or one of its children.
Child identifiers are increasing integers beginning with 0.
The identifier CHILDID_SELF represents the control itself.

| Method Summary | |
| public void | getDescription(AccessibleEvent e)
Sent when an accessibility client requests a description
of the control, or a description of a child of the control.
The default behavior is to do nothing.
This is a textual description of the control or child's visual
appearance, which is typically only necessary if it cannot be
determined from other properties such as role.
Return the description of the control or specified child in
the result field of the event object. | | public void | getHelp(AccessibleEvent e)
Sent when an accessibility client requests the help string
of the control, or the help string of a child of the control.
The default behavior is to do nothing.
The information in this property should be similar to the help
provided by toolTipText. | | public void | getKeyboardShortcut(AccessibleEvent e)
Sent when an accessibility client requests the keyboard shortcut
of the control, or the keyboard shortcut of a child of the control.
The default behavior is to do nothing.
A keyboard shortcut can either be a mnemonic, or an accelerator.
As a general rule, if the control or child can receive keyboard focus,
then you should expose its mnemonic, and if it cannot receive keyboard
focus, then you should expose its accelerator.
Return the keyboard shortcut string of the control or specified child
in the result field of the event object. | | public void | getName(AccessibleEvent e)
Sent when an accessibility client requests the name
of the control, or the name of a child of the control.
The default behavior is to do nothing.
Return the name of the control or specified child in the
result field of the event object. |
| getDescription | | public void getDescription(AccessibleEvent e)(Code) | | Sent when an accessibility client requests a description
of the control, or a description of a child of the control.
The default behavior is to do nothing.
This is a textual description of the control or child's visual
appearance, which is typically only necessary if it cannot be
determined from other properties such as role.
Return the description of the control or specified child in
the result field of the event object. Returning
an empty string tells the client that the control or child
does not have a description, and returning null tells the
client to use the platform description.
Parameters:
e - an event object containing the following fields:- childID [IN] - an identifier specifying the control or one of its children
- result [OUT] - the requested description string, or null
|
| getHelp | | public void getHelp(AccessibleEvent e)(Code) | | Sent when an accessibility client requests the help string
of the control, or the help string of a child of the control.
The default behavior is to do nothing.
The information in this property should be similar to the help
provided by toolTipText. It describes what the control or child
does or how to use it, as opposed to getDescription, which
describes appearance.
Return the help string of the control or specified child in
the result field of the event object. Returning
an empty string tells the client that the control or child
does not have a help string, and returning null tells the
client to use the platform help string.
Parameters:
e - an event object containing the following fields:- childID [IN] - an identifier specifying the control or one of its children
- result [OUT] - the requested help string, or null
|
| getKeyboardShortcut | | public void getKeyboardShortcut(AccessibleEvent e)(Code) | | Sent when an accessibility client requests the keyboard shortcut
of the control, or the keyboard shortcut of a child of the control.
The default behavior is to do nothing.
A keyboard shortcut can either be a mnemonic, or an accelerator.
As a general rule, if the control or child can receive keyboard focus,
then you should expose its mnemonic, and if it cannot receive keyboard
focus, then you should expose its accelerator.
Return the keyboard shortcut string of the control or specified child
in the result field of the event object. Returning an
empty string tells the client that the control or child does not
have a keyboard shortcut string, and returning null tells the client
to use the platform keyboard shortcut string.
Parameters:
e - an event object containing the following fields:- childID [IN] - an identifier specifying the control or one of its children
- result [OUT] - the requested keyboard shortcut string (example: "ALT+N"), or null
|
| getName | | public void getName(AccessibleEvent e)(Code) | | Sent when an accessibility client requests the name
of the control, or the name of a child of the control.
The default behavior is to do nothing.
Return the name of the control or specified child in the
result field of the event object. Returning
an empty string tells the client that the control or child
does not have a name, and returning null tells the client
to use the platform name.
Parameters:
e - an event object containing the following fields:- childID [IN] - an identifier specifying the control or one of its children
- result [OUT] - the requested name string, or null
