Class StaticLayoutManager

java.lang.Object
  org.pentaho.reporting.engine.classic.core.layout.StaticLayoutManager

All Implemented Interfaces:

BandLayoutManager

Deprecated. This layout manager is no longer used.

public class StaticLayoutManager
extends Object
implements BandLayoutManager

An implementation of the BandLayoutManager interface.

Rule: Bands can have minimum, max and pref size defined. These values are hints for the layout container, no restrictions. If min and pref are '0', they are ignored. MaxSize is never ignored.

Elements that have the "dynamic" flag set, are checked for their content-bounds. This operation is expensive, so this is only done if really needed. The dynamic flag will influence the height of an element, a valid width must be already set.

Invisible elements within the layouted band are not evaluated. This layout manager will ignore invisible child bands and -elements.

Note to everybody who tries to understand this class: This class is full of old compatibility code, this class is not designed to be smart, or suitable for complex layouts. The only purpose of this class is to maintain backward compatiblity with older releases of JFreeReport.

The use of relative elements (the one's with 100% should be considered carefully, as these elements are not fully predictable).

Method Detail

preferredLayoutSize

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

Deprecated.

Calculates the preferred layout size for a band. The band is limited to the given container bounds as well as to the own maximum size.

The preferred size of non-absolute elements is calculated by using the parents dimensions supplied in containerDims. Elements with a width or height of 100% will consume all available space of the parent.

Specified by:

preferredLayoutSize in interface BandLayoutManager

Parameters:

b - the band.

containerDims - the maximum size the band should use for that container.

maxUsableSize -

support - the layout support used to compute sizes.

Returns:

the preferred size.

minimumLayoutSize

public StrictDimension minimumLayoutSize(Band b,
                                         StrictDimension containerBounds,
                                         StrictDimension maxUsableSize,
                                         LayoutSupport support,
                                         ExpressionRuntime runtime)

Deprecated.

Calculates the minimum layout size for a band. The width for the child elements are not calculated, as we assume that the width's are defined fixed within the parent.

Specified by:

minimumLayoutSize in interface BandLayoutManager

Parameters:

b - the band.

containerBounds - the bounds of the bands parents.

maxUsableSize -

support - the layout support used to compute sizes.

Returns:

the minimum size.

doLayout

public void doLayout(Band b,
                     LayoutSupport support,
                     ExpressionRuntime runtime)

Deprecated.

Layout a single band with all elements contained within the band.

The band has its BOUNDS already set and all elements are laid out within these bounds. The band's properties will not be changed during the layouting.

This layout manager requires that all direct child elements have the ABSOLUTE_POS and MINIMUM_SIZE properties set to valid values.

Specified by:

doLayout in interface BandLayoutManager

Parameters:

b - the band to lay out.

support - the layout support used to compute sizes.

Throws:

IllegalStateException - if the bands has no bounds set.
