Public Constructors

public List.AccessibleAWTList.AccessibleAWTListChild (List parent, int indexInParent)

Public Methods

public void addFocusListener (FocusListener l)

Adds the specified focus listener to receive focus events from this component.

Parameters
l the focus listener

public boolean contains (Point p)

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.

Parameters
p the Point relative to the coordinate system of the object
Returns
  • true if object contains Point; otherwise false
See Also

public Accessible getAccessibleAt (Point p)

Returns the Accessible child, if one exists, contained at the local coordinate Point.

Parameters
p the point relative to the coordinate system of this object
Returns
  • the Accessible, if it exists, at the specified location; otherwise null

public Accessible getAccessibleChild (int i)

Return the specified Accessible child of the object. The Accessible children of an Accessible object are zero-based, so the first child of an Accessible child is at index 0, the second child is at index 1, and so on.

Parameters
i zero-based index of child
Returns
  • the Accessible child of the object

public int getAccessibleChildrenCount ()

Returns the number of accessible children of the object.

Returns
  • the number of accessible children of the object.

public AccessibleContext getAccessibleContext ()

Gets the AccessibleContext for this object. In the implementation of the Java Accessibility API for this class, return this object, which acts as its own AccessibleContext.

Returns
  • this object

public int getAccessibleIndexInParent ()

Get the 0-based index of this object in its accessible parent.

Returns
  • the 0-based index of this object in its parent; -1 if this object does not have an accessible parent.

public AccessibleRole getAccessibleRole ()

Get the role of this object.

Returns
  • an instance of AccessibleRole describing the role of the object
See Also

public AccessibleStateSet getAccessibleStateSet ()

Get the state set of this object. The AccessibleStateSet of an object is composed of a set of unique AccessibleState's. A change in the AccessibleStateSet of an object will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_STATE_PROPERTY property.

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

public Color getBackground ()

Get the background color of this object.

Returns
  • the background color, if supported, of the object; otherwise, null

public Rectangle getBounds ()

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.

Returns
  • A rectangle indicating this component's bounds; null if this object is not on the screen.
See Also

public Cursor getCursor ()

Get the Cursor of this object.

Returns
  • the Cursor, if supported, of the object; otherwise, null

public Font getFont ()

Get the Font of this object.

Returns
  • the Font,if supported, for the object; otherwise, null
See Also

public FontMetrics getFontMetrics (Font f)

Get the FontMetrics of this object.

Parameters
f the Font
Returns
  • the FontMetrics, if supported, the object; otherwise, null
See Also

public Color getForeground ()

Get the foreground color of this object.

Returns
  • the foreground color, if supported, of the object; otherwise, null

public Locale getLocale ()

Gets the locale of the component. If the component does not have a locale, then the locale of its parent is returned.

Returns
  • This component's locale. If this component does not have a locale, the locale of its parent is returned.
Throws
IllegalComponentStateException If the Component does not have its own locale and has not yet been added to a containment hierarchy such that the locale can be determined from the containing parent.

public Point getLocation ()

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.

Returns
  • An instance of Point representing the top-left corner of the objects's bounds in the coordinate space of the screen; null if this object or its parent are not on the screen

public Point getLocationOnScreen ()

Returns the location of the object on the screen.

Returns
  • location of object on screen; null if this object is not on the screen

public Dimension getSize ()

Returns the size of this object in the form of a Dimension object. The height field of the Dimension object contains this objects's height, and the width field of the Dimension object contains this object's width.

Returns
  • A Dimension object that indicates the size of this component; null if this object is not on the screen

public boolean isEnabled ()

Determine if the object is enabled. Objects that are enabled will also have the AccessibleState.ENABLED state set in their AccessibleStateSet.

Returns
  • true if object is enabled; otherwise, false

public boolean isFocusTraversable ()

Returns whether this object can accept focus or not. Objects that can accept focus will also have the AccessibleState.FOCUSABLE state set in their AccessibleStateSet.

Returns
  • true if object can accept focus; otherwise false

public boolean isShowing ()

Determine if the object is showing. This is determined by checking the visibility of the object and visibility of the object ancestors. Note: this will return true even if the object is obscured by another (for example, it to object is underneath a menu that was pulled down).

Returns
  • true if object is showing; otherwise, false

public boolean isVisible ()

Determine if the object is visible. Note: this means that the object intends to be visible; however, it may not be showing on the screen because one of the objects that this object is contained by is currently not visible. To determine if an object is showing on the screen, use isShowing().

Objects that are visible will also have the AccessibleState.VISIBLE state set in their AccessibleStateSet.

Returns
  • true if object is visible; otherwise, false

public void removeFocusListener (FocusListener l)

Removes the specified focus listener so it no longer receives focus events from this component.

Parameters
l the focus listener

public void requestFocus ()

Requests focus for this object. If this object cannot accept focus, nothing will happen. Otherwise, the object will attempt to take focus.

public void setBackground (Color c)

Set the background color of this object.

Parameters
c the new Color for the background

public void setBounds (Rectangle r)

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.

Parameters
r rectangle indicating this component's bounds
See Also

public void setCursor (Cursor cursor)

Set 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.

Parameters
cursor the new Cursor for the object
See Also

public void setEnabled (boolean b)

Set the enabled state of the object.

Parameters
b if true, enables this object; otherwise, disables it
See Also

public void setFont (Font f)

Set the Font of this object.

Parameters
f the new Font for the object
See Also

public void setForeground (Color c)

Set the foreground color of this object.

Parameters
c the new Color for the foreground
See Also

public void setLocation (Point p)

Sets the location of the object relative to the parent.

Parameters

Resizes this object so that it has width and height.

Parameters
d - The dimension specifying the new size of the object.
See Also

public void setVisible (boolean b)

Set the visible state of the object.

Parameters
b if true, shows this object; otherwise, hides it
