Method Summary

void	doLayout(Band b, LayoutSupport support) Performs the layout of a band.
StrictDimension	minimumLayoutSize(Band b, StrictDimension containerDims, StrictDimension maxUsableSize, LayoutSupport support) Calculates the minimum layout size for a band.
StrictDimension	preferredLayoutSize(Band b, StrictDimension containerDims, StrictDimension maxUsableSize, LayoutSupport support) Calculates the preferred layout size for a band.

Field Detail

LAYOUTMANAGER

public static final StyleKey LAYOUTMANAGER

The LayoutManager styleKey. All bands must define their LayoutManager by using this key when using the PageableReportProcessor.

Method Detail

preferredLayoutSize

public StrictDimension preferredLayoutSize(Band b,
                                           StrictDimension containerDims,
                                           StrictDimension maxUsableSize,
                                           LayoutSupport support)

Calculates the preferred layout size for a band.

Parameters:

b - the band.

containerDims - the bounds of the surrounding container.

maxUsableSize - the maximum size that can be granted by the surrounding container.

support - the layout support used to compute sizes.

Returns:

the preferred size.

minimumLayoutSize

public StrictDimension minimumLayoutSize(Band b,
                                         StrictDimension containerDims,
                                         StrictDimension maxUsableSize,
                                         LayoutSupport support)

Calculates the minimum layout size for a band.

Parameters:

b - the band.

containerDims - the bounds of the surrounding container.

maxUsableSize -

support - the layout support used to compute sizes.

Returns:

the minimum size.

doLayout

public void doLayout(Band b,
                     LayoutSupport support)

Performs the layout of a band.

Parameters:

b - the band.

support - the layout support used to compute sizes.
