      Overrides:
      getAccessibleChildrenCount in class JComponent.AccessibleJComponent
      Returns:
      the number of accessible children in the object.

    • getAccessibleChild

      public Accessible getAccessibleChild(int i)
      Returns the nth Accessible child of the object.
      Overrides:
      getAccessibleChild in class JComponent.AccessibleJComponent
      Parameters:
      i - zero-based index of child
      Returns:
      the nth Accessible child of the object

      Get the role of this object.
      Overrides:
      getAccessibleRole in class JMenuItem.AccessibleJMenuItem

      See Also:

    • getAccessibleSelection

      public AccessibleSelection getAccessibleSelection()

      Overrides:
      getAccessibleSelection in class AccessibleContext
      Returns:
      this object
      See Also:

    • getAccessibleSelectionCount

      public int getAccessibleSelectionCount()
      Returns 1 if a sub-menu is currently selected in this menu.
      Specified by:
      getAccessibleSelectionCount in interface AccessibleSelection
      Returns:
      1 if a menu is currently selected, else 0

    • getAccessibleSelection

      public Accessible getAccessibleSelection(int i)
      Returns the currently selected sub-menu if one is selected, otherwise null (there can only be one selection, and it can only be a sub-menu, as otherwise menu items don't remain selected).
      Specified by:
      getAccessibleSelection in interface AccessibleSelection
      Parameters:
      i - the zero-based index of selected children
      Returns:
      the i-th selected child
      See Also:

    • isAccessibleChildSelected

      public boolean isAccessibleChildSelected(int i)
      Returns true if the current child of this object is selected (that is, if this child is a popped-up submenu).
      Specified by:
      isAccessibleChildSelected in interface AccessibleSelection
      Parameters:
      i - the zero-based index of the child in this Accessible object.
      Returns:
      true if the current child of this object is selected; else false
      See Also:

    • addAccessibleSelection

      public void addAccessibleSelection(int i)
      Selects the ith menu in the menu. If that item is a submenu, it will pop up in response. If a different item is already popped up, this will force it to close. If this is a sub-menu that is already popped up (selected), this method has no effect.
      Specified by:
      addAccessibleSelection in interface AccessibleSelection
      Parameters:
      i - the index of the item to be selected
      See Also:

    • removeAccessibleSelection

      public void removeAccessibleSelection(int i)
      Removes the nth item from the selection. In general, menus can only have one item within them selected at a time (e.g. one sub-menu popped open).
      Specified by:
      removeAccessibleSelection in interface AccessibleSelection
      Parameters:
      i - the zero-based index of the selected item
      See Also:

    • clearAccessibleSelection

      public void clearAccessibleSelection()
      Clears the selection in the object, so that nothing in the object is selected. This will close any open sub-menu.
      Specified by:
      clearAccessibleSelection in interface AccessibleSelection

    • selectAllAccessibleSelection

      public void selectAllAccessibleSelection()
      Normally causes every selected item in the object to be selected if the object supports multiple selections. This method makes no sense in a menu bar, and so does nothing.
      Specified by:
      selectAllAccessibleSelection in interface AccessibleSelection
