used to provide
default support for accessibility. This class is not meant
to be used directly by application developers, but is instead
meant only to be subclassed by menu component developers.
The class used to obtain the accessible role for this object.
Method from java.awt.MenuComponent$AccessibleAWTMenuComponent Detail: |
public void addAccessibleSelection(int i) {
// To be fully implemented in a future release
}
Adds the specified Accessible child of the object
to the object's selection. If the object supports multiple selections,
the specified child is added to any existing selection, otherwise
it replaces any existing selection in the object. If the
specified child is already selected, this method has no effect. |
public void addFocusListener(FocusListener l) {
// Not supported for MenuComponents
}
Adds the specified focus listener to receive focus events from this
component. |
public void clearAccessibleSelection() {
// To be fully implemented in a future release
}
Clears the selection in the object, so that no children in the
object are selected. |
public boolean contains(Point p) {
return false; // Not supported for MenuComponents
}
Checks whether the specified point is within this object's bounds,
where the point's x and y coordinates are defined to be relative to
the coordinate system of the object. |
public Accessible getAccessibleAt(Point p) {
return null; // MenuComponents don't have children
}
Returns the Accessible child, if one exists,
contained at the local coordinate Point .
If there is no Accessible child, null
is returned. |
public Accessible getAccessibleChild(int i) {
return null; // MenuComponents don't have children
}
Returns the nth Accessible child of the object. |
public int getAccessibleChildrenCount() {
return 0; // MenuComponents don't have children
}
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. |
public AccessibleComponent getAccessibleComponent() {
return this;
}
Gets the AccessibleComponent associated with
this object if one exists. Otherwise return null . |
public String getAccessibleDescription() {
return accessibleDescription;
}
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). |
public int getAccessibleIndexInParent() {
return MenuComponent.this.getAccessibleIndexInParent();
}
Gets the index of this object in its accessible parent. |
public String getAccessibleName() {
return accessibleName;
}
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. |
public Accessible getAccessibleParent() {
if (accessibleParent != null) {
return accessibleParent;
} else {
MenuContainer parent = MenuComponent.this.getParent();
if (parent instanceof Accessible) {
return (Accessible) parent;
}
}
return null;
}
Gets the Accessible parent of this object.
If the parent of this object implements Accessible ,
this method should simply return getParent . |
public AccessibleRole getAccessibleRole() {
return AccessibleRole.AWT_COMPONENT; // Non-specific -- overridden in subclasses
}
Gets the role of this object. |
public AccessibleSelection getAccessibleSelection() {
return this;
}
Gets the AccessibleSelection associated with this
object which allows its Accessible children to be selected. |
public Accessible getAccessibleSelection(int i) {
return null; // To be fully implemented in a future release
}
Returns an Accessible representing the specified
selected child in the object. If there isn't a selection, or there are
fewer children selected than the integer passed in, the return
value will be null .
Note that the index represents the i-th selected child, which
is different from the i-th child. |
public int getAccessibleSelectionCount() {
return 0; // To be fully implemented in a future release
}
Returns the number of Accessible children currently selected.
If no children are selected, the return value will be 0. |
public AccessibleStateSet getAccessibleStateSet() {
return MenuComponent.this.getAccessibleStateSet();
}
Gets the state of this object. |
public Color getBackground() {
return null; // Not supported for MenuComponents
}
Gets the background color of this object. |
public Rectangle getBounds() {
return null; // Not supported for MenuComponents
}
Gets the bounds of this object in the form of a
Rectangle object.
The bounds specify this object's width, height, and location
relative to its parent. |
public Cursor getCursor() {
return null; // Not supported for MenuComponents
}
Gets the Cursor of this object. |
public Font getFont() {
return MenuComponent.this.getFont();
}
Gets the Font of this object. |
public FontMetrics getFontMetrics(Font f) {
return null; // Not supported for MenuComponents
}
Gets the FontMetrics of this object. |
public Color getForeground() {
return null; // Not supported for MenuComponents
}
Gets the foreground color of this object. |
public Locale getLocale() {
MenuContainer parent = MenuComponent.this.getParent();
if (parent instanceof Component)
return ((Component)parent).getLocale();
else
return java.util.Locale.getDefault();
}
Returns the locale of this object. |
public Point getLocation() {
return null; // Not supported for MenuComponents
}
Gets the location of the object relative to the parent in the form
of a point specifying the object's top-left corner in the screen's
coordinate space. |
public Point getLocationOnScreen() {
return null; // Not supported for MenuComponents
}
Returns the location of the object on the screen. |
public Dimension getSize() {
return null; // Not supported for MenuComponents
}
Returns the size of this object in the form of a
Dimension object. The height field of
the Dimension object contains this object's
height, and the width field of the Dimension
object contains this object's width. |
public boolean isAccessibleChildSelected(int i) {
return false; // To be fully implemented in a future release
}
Determines if the current child of this object is selected. |
public boolean isEnabled() {
return true; // Not supported for MenuComponents
}
Determines if the object is enabled. |
public boolean isFocusTraversable() {
return true; // Not supported for MenuComponents
}
Returns whether this object can accept focus or not. |
public boolean isShowing() {
return true; // Not supported for MenuComponents
}
Determines if the object is showing. This is determined by checking
the visibility of the object and ancestors of the object. Note:
this will return true even if the object is obscured by another
(for example, it happens to be underneath a menu that was pulled
down). |
public boolean isVisible() {
return true; // Not supported for MenuComponents
}
Determines if the object is visible. Note: this means that the
object intends to be visible; however, it may not in fact be
showing on the screen because one of the objects that this object
is contained by is not visible. To determine if an object is
showing on the screen, use isShowing . |
public void removeAccessibleSelection(int i) {
// To be fully implemented in a future release
}
Removes the specified child of the object from the object's
selection. If the specified item isn't currently selected, this
method has no effect. |
public void removeFocusListener(FocusListener l) {
// Not supported for MenuComponents
}
Removes the specified focus listener so it no longer receives focus
events from this component. |
public void requestFocus() {
// Not supported for MenuComponents
}
Requests focus for this object. |
public void selectAllAccessibleSelection() {
// To be fully implemented in a future release
}
Causes every child of the object to be selected
if the object supports multiple selections. |
public void setBackground(Color c) {
// Not supported for MenuComponents
}
Sets the background color of this object.
(For transparency, see isOpaque .) |
public void setBounds(Rectangle r) {
// Not supported for MenuComponents
}
Sets the bounds of this object in the form of a
Rectangle object.
The bounds specify this object's width, height, and location
relative to its parent. |
public void setCursor(Cursor cursor) {
// Not supported for MenuComponents
}
Sets the Cursor of this object.
The method may have no visual effect if the Java platform
implementation and/or the native system do not support
changing the mouse cursor shape. |
