Classes Added in SDK 1.3 and 1.4
The 1.3 and 1.4 SDKs both augmented the Accessibility package. Three interfaces in
particular stand out: AccessibleIcon,
AccessibleEditableText, and AccessibleTable.
The AccessibleIcon Interface
Added in the 1.3 release, the AccessibleIcon interface allows assistive technologies to get
information about any icons on a component (such as a button or a
label). Notice that the getAccessibleIcon(
) method from the AccessibleContext class returns an array of
icons. While Swing labels and buttons do not support multiple icons,
custom components can freely do so and still provide useful
information to assistive technologies.
Properties
Table 25-12
lists the three descriptive properties for AccessibleIcon. accessibleIcon -Description is the
most useful property and can be set through the accessible context
as it is on other components.
Table 25-12. AccessibleIcon properties
Property | Data type | get | is | set | Default value |
|---|---|---|---|---|---|
accessibleIconDescription | String | · | · | ||
accessibleIconHeight | int | · | |||
accessibleIconWidth | int | · |
The AccessibleEditableText Interface
While the AccessibleText
interface has always been part of Swing, an editable
representation for text did not exist. With the release of the 1.4
SDK, AccessibleEditableText fills
that gap.
Property
As an extension of the AccessibleText interface, most of the
properties for AccessibleEditableText are inherited. One
writable property to alter the contents of the text component,
textContents , was added. It is shown in Table 25-13.
