  java.awt.FlowLayout
      info.monitorenter.gui.chart.layouts.FlowLayoutCorrectMinimumSize

All Implemented Interfaces:

java.awt.LayoutManager, java.io.Serializable

public class FlowLayoutCorrectMinimumSize
extends java.awt.FlowLayout

A flow layout that claims the correct height of the component managed in case the available width is known. The standard FlowLayout does not claim the correct size but chooses the maximum width of all components to render which is worthless as the fact of flow breaks is not taken into account.

This class is inspired by the sun class FlowLayout with modifications to the methods preferredLayoutSize(Container) and minimumLayoutSize(Container).

Constructor Detail

FlowLayoutCorrectMinimumSize

public FlowLayoutCorrectMinimumSize(int align)

Constructs a new FlowLayout with the specified alignment and a default 5-unit horizontal and vertical gap. The value of the alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, FlowLayout.CENTER, FlowLayout.LEADING, or FlowLayout.TRAILING.

Parameters:

align - the alignment value

FlowLayoutCorrectMinimumSize

public FlowLayoutCorrectMinimumSize(int align,
                                    int hgap,
                                    int vgap)

Creates a new flow layout manager with the indicated alignment and the indicated horizontal and vertical gaps.

The value of the alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, FlowLayout.CENTER, FlowLayout.LEADING, or FlowLayout.TRAILING.

Parameters:

align - the alignment value

hgap - the horizontal gap between components and between the components and the borders of the Container

vgap - the vertical gap between components and between the components and the borders of the Container

Method Detail

layoutContainer

public void layoutContainer(java.awt.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 FlowLayout object.

Specified by:

layoutContainer in interface java.awt.LayoutManager

Overrides:

layoutContainer in class java.awt.FlowLayout

Parameters:

target - the specified component being laid out

See Also:

Container, Container.doLayout()

minimumLayoutSize

public java.awt.Dimension minimumLayoutSize(java.awt.Container target)

Returns the minimum dimensions needed to layout the visible components contained in the specified target container.

Specified by:

minimumLayoutSize in interface java.awt.LayoutManager

Overrides:

minimumLayoutSize in class java.awt.FlowLayout

Parameters:

target - the container that needs to be laid out

Returns:

the minimum dimensions to lay out the subcomponents of the specified container

See Also:

preferredLayoutSize(java.awt.Container), Container, Container.doLayout()

preferredLayoutSize

public java.awt.Dimension preferredLayoutSize(java.awt.Container target)

Returns the preferred dimensions for this layout given the visible components in the specified target container.

Specified by:

preferredLayoutSize in interface java.awt.LayoutManager

Overrides:

preferredLayoutSize in class java.awt.FlowLayout

Parameters:

target - the container that needs to be laid out

Returns:

the preferred dimensions to lay out the subcomponents of the specified container
