Method Detail

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.

Overrides:

[getAccessibleChildrenCount](../../java/awt/Component.AccessibleAWTComponent.html#getAccessibleChildrenCount%28%29) in class [Component.AccessibleAWTComponent](../../java/awt/Component.AccessibleAWTComponent.html "class in java.awt")

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](../../java/awt/Component.AccessibleAWTComponent.html#getAccessibleChild%28int%29) in class [Component.AccessibleAWTComponent](../../java/awt/Component.AccessibleAWTComponent.html "class in java.awt")

Parameters:

i - zero-based index of child

Returns:

the nth Accessible child of the object

getAccessibleAt

public Accessible getAccessibleAt(Point p)

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

Specified by:

[getAccessibleAt](../../javax/accessibility/AccessibleComponent.html#getAccessibleAt%28java.awt.Point%29) in interface [AccessibleComponent](../../javax/accessibility/AccessibleComponent.html "interface in javax.accessibility")

Overrides:

Parameters:

p - the point defining the top-left corner of the Accessible, given in the coordinate space of the object's parent

Returns:

the Accessible, if it exists, at the specified location; else null

addPropertyChangeListener
