isAncestorOfFocusedComponent

public static boolean isAncestorOfFocusedComponent(Component c)

Returns:

returns true if the component of one of its child has the focus

getFocusableComponentOrChild

public static Component getFocusableComponentOrChild(Component c)

Deprecated. replaced by getFocusableComponentOrChild(Component, boolean)

                                                     boolean deepest)

Returns the first component in the tree of c that can accept the focus.

Parameters:

c - the root of the component hierarchy to search

deepest - if deepest is true the method will return the first and deepest component that can accept the focus. For example, if both a child and its parent are focusable and deepest is true, the child is returned.

Puts the focus on the first component in the tree of c that can accept the focus.

Parameters:

c - the root of the component hierarchy to search

deepest - if deepest is true the method will focus the first and deepest component that can accept the focus. For example, if both a child and its parent are focusable and deepest is true, the child is focused.
