w - the window to center

parent - the window to center within

setEnabled

public static void setEnabled(Component component,
                              boolean enabled)

Enable or disable the specified component and, if it's a Container, its children components.

Parameters:

component - the component to modify

enabled - the enabled state

getMaxSize

public static Dimension getMaxSize(Collection components)

Return the largest size of the component in the given collection.

Parameters:

components - the collection of components

setSameSize

public static void setSameSize(Component[] components)

Fix the size of all the components in the array to the size of the largest component.

Parameters:

components - the array of components

setSameSize

public static void setSameSize(Collection components)

Fix the size of all the components in the collection to the size of the largest component.

Parameters:

components - the collection of components

setSameSize

public static void setSameSize(Collection components,
                               Dimension size)

Fix the size of all the components in the collection.

Parameters:

components - the collection of components
