public final class CanvasMajorAxisLayoutStep
extends AbstractMajorAxisLayoutStep

This processes the second step of the vertical-layouting.

At this point, the static height of all elements is known (that is the height of all elements that do not use percentages in either the y or height properties).

That height is then used as base-value to resolve all relative heights and y positions and the layouting is redone.

public CanvasMajorAxisLayoutStep()

Method Detail

compute

public void compute(LogicalPageBox pageBox)

Overrides:

compute in class AbstractMajorAxisLayoutStep

initialize

public void initialize(OutputProcessorMetaData metaData)

startBlockLevelBox

protected boolean startBlockLevelBox(RenderBox box)

Overrides:

startBlockLevelBox in class IterateVisualProcessStep

processBlockLevelNode

protected void processBlockLevelNode(RenderNode node)

Overrides:

processBlockLevelNode in class IterateVisualProcessStep

finishBlockLevelBox

protected void finishBlockLevelBox(RenderBox box)

Overrides:

finishBlockLevelBox in class IterateVisualProcessStep

processParagraphChilds

protected void processParagraphChilds(ParagraphRenderBox box)

Specified by:

processParagraphChilds in class IterateVisualProcessStep

startCanvasLevelBox

protected boolean startCanvasLevelBox(RenderBox box)

Overrides:

startCanvasLevelBox in class IterateVisualProcessStep

processCanvasLevelNode

protected void processCanvasLevelNode(RenderNode node)

Overrides:

processCanvasLevelNode in class IterateVisualProcessStep

finishCanvasLevelBox

protected void finishCanvasLevelBox(RenderBox box)

Finishes up a canvas level box. This updates/affects the height of the parent, as the canvas model defines that the parent always fully encloses all of its childs.

When no preferred height is defined, the height of an element is the maximum of its minimum-height and the absolute height of all of its direct children.

To resolve the value of percentages, the system uses the maximum of the parent's height and the maximum of all (y + height) of all children.)
