Constructor Detail

• AccessibleAWTMenuComponent

  protected AccessibleAWTMenuComponent()

  Although the class is abstract, this should be called by all sub-classes.

Method Detail

• 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:

  AccessibleContext.setAccessibleDescription(java.lang.String)

• getAccessibleRole

  public AccessibleRole getAccessibleRole()

  Gets the role of this object.

  Specified by:

  getAccessibleRole in class AccessibleContext

  Returns:

  an instance of AccessibleRole describing the role of the object

  See Also:

• getAccessibleStateSet

  public AccessibleStateSet getAccessibleStateSet()

  Gets the state of this object.

  Specified by:

  getAccessibleStateSet in class AccessibleContext

  Returns:

  an instance of AccessibleStateSet containing the current state set of the object

  See Also:

  AccessibleState

• getAccessibleParent

  public Accessible getAccessibleParent()

  Gets the Accessible parent of this object. If the parent of this object implements Accessible, this method should simply return getParent.

• getAccessibleIndexInParent

  public int getAccessibleIndexInParent()

  Gets the index of this object in its accessible parent.

  Specified by:

  getAccessibleIndexInParent in class AccessibleContext

  See Also:

  getAccessibleParent()

• getAccessibleChildrenCount

  public int getAccessibleChildrenCount()

  Returns the number of accessible children in the object. If all of the children of this object implement Accessible, then this method should return the number of children of this object.
