Method Detail
-
getAccessibleSelection
public AccessibleSelection getAccessibleSelection()
Gets the
AccessibleSelectionassociated with this object which allows itsAccessiblechildren to be selected.- Overrides:
getAccessibleSelectionin classAccessibleContext- Returns:
AccessibleSelectionif supported by object; else returnnull- See Also:
AccessibleSelection
-
getAccessibleName
public String getAccessibleName()
Gets the accessible name of this object. This should almost never return
java.awt.MenuComponent.getName, as that generally isn't a localized name, and doesn't have meaning for the user. If the object is fundamentally a text object (e.g. a menu item), the accessible name should be the text of the object (e.g. "save"). If the object has a tooltip, the tooltip text may also be an appropriate String to return.- Overrides:
getAccessibleNamein classAccessibleContext- Returns:
- the localized name of the object -- can be
nullif this object does not have a name - See Also:
AccessibleContext.setAccessibleName(java.lang.String)
-
getAccessibleDescription
public String getAccessibleDescription()
Gets the accessible description of this object. This should be a concise, localized description of what this object is - what is its meaning to the user. If the object has a tooltip, the tooltip text may be an appropriate string to return, assuming it contains a concise description of the object (instead of just the name of the object - e.g. a "Save" icon on a toolbar that had "save" as the tooltip text shouldn't return the tooltip text as the description, but something like "Saves the current text document" instead).
- Overrides:
getAccessibleDescriptionin classAccessibleContext- Returns:
- the localized description of the object -- can be
nullif this object does not have a description - See Also:
AccessibleContext.setAccessibleDescription(java.lang.String)
-
