MenuComponent.AccessibleAWTMenuComponent
protected MenuComponent.AccessibleAWTMenuComponent()
-
Although the class is abstract, this should be called by all sub-classes.
getAccessibleSelection
public AccessibleSelection getAccessibleSelection()
-
Gets the AccessibleSelection associated with this object which allows its Accessible children to be selected.
-
-
Overrides:
-
getAccessibleSelection
in class
AccessibleContext
-
-
Returns:
-
AccessibleSelection if supported by object; else return null
-
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:
-
getAccessibleName
in class
AccessibleContext
-
-
Returns:
-
the localized name of the object -- can be null if 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:
-
getAccessibleDescription
in class
AccessibleContext
-
-
Returns:
-
the localized description of the object -- can be null if this object does not have a description
-
See Also:
-
