public static void centerWindowOnComponent(Window window,
                                           Component over)

Centers the window over a component (usually another window). The window must already have been sized.

Parameters:

window - the window to center

over - the component over which to center it

isAncestorOfFocusedComponent

public static boolean isAncestorOfFocusedComponent(Component c)

Parameters:

c - the component

Returns:

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

getFocusableComponentOrChild

public static Component getFocusableComponentOrChild(Component c,
                                                     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.

Returns:

the first component that can accept focus

focusComponentOrChild(java.awt.Component)

focusComponentOrChild

public static Component focusComponentOrChild(Component c)

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

Parameters:

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.
