Class IlvBetterFlowLayout

java.lang.Object

java.awt.FlowLayout

ilog.views.util.swing.layout.IlvBetterFlowLayout

All Implemented Interfaces:

LayoutManager, Serializable

public class IlvBetterFlowLayout
extends FlowLayout

A subclass of FlowLayout that better computes the preferred and minimum size of a container, taking into account wrapping. For example, you can use this layout to put two toolbars in a panel placed at the north of a BorderLayout. With a standard FlowLayout, the north panel would always be the height of one toolbar, whereas this subclass lets the north panel resize itself so that both toolbars are placed one on top of another if the parent is not wide enough to put them side-by-side.

Method Detail

layoutContainer

public void layoutContainer(Container target)

Lays out the container. This method lets each visible component take its preferred size by reshaping the components in the target container in order to satisfy the alignment of this IlvBetterFlowLayout object.

Specified by:

layoutContainer in interface LayoutManager

Overrides:

layoutContainer in class FlowLayout

Parameters:

target - the specified component being laid out

preferredLayoutSize

public Dimension preferredLayoutSize(Container target)

Compute the preferred size of the container.

Specified by:

preferredLayoutSize in interface LayoutManager

Overrides:

preferredLayoutSize in class FlowLayout

Parameters:

target - The container.

minimumLayoutSize

public Dimension minimumLayoutSize(Container target)

Compute the minimum size of the container.

Specified by:

minimumLayoutSize in interface LayoutManager

Overrides:

minimumLayoutSize in class FlowLayout

Parameters:

target - The container.
