Constructor Detail

WrappingFlowLayout

public WrappingFlowLayout()

Constructs a new WrappingFlowLayout with a centered alignment and a default 5-unit horizontal and vertical gap.

WrappingFlowLayout

public WrappingFlowLayout(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 WrappingFlowLayout, WrappingFlowLayout, or WrappingFlowLayout.

Parameters:

align - the alignment value

WrappingFlowLayout

public WrappingFlowLayout(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 WrappingFlowLayout, WrappingFlowLayout, or WrappingFlowLayout.

Parameters:

align - the alignment value

hgap - the horizontal gap between components

vgap - the vertical gap between components

Method Detail

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 component which needs to be laid out

Returns:

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

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 component which needs to be laid out

Returns:

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

layoutContainer

public void layoutContainer(java.awt.Container target)

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

Specified by:

layoutContainer in interface java.awt.LayoutManager

Overrides:

layoutContainer in class java.awt.FlowLayout

Parameters:

target - the specified component being laid out
