public class TableRenderer
extends AbstractRenderer

This class represents the renderer object for a Table object. It will delegate its drawing operations on to the CellRenderer instances associated with the table cells.

Method Summary

Modifier and Type	Method and Description
void	addChild(IRenderer renderer) Adds a child to the current renderer
protected float[]	calculateScaledColumnWidths(Table tableModel, float tableWidth)

Field Detail

rows

protected List<CellRenderer[]> rows

rowRange

protected Table.RowRange rowRange

headerRenderer

protected TableRenderer headerRenderer

footerRenderer

protected TableRenderer footerRenderer

isOriginalNonSplitRenderer

protected boolean isOriginalNonSplitRenderer

True for newly created renderer. For split renderers this is set to false. Used for tricky layout.

Constructor Detail

TableRenderer

public TableRenderer(Table modelElement,
                     Table.RowRange rowRange)

Creates a TableRenderer from a Table which will partially render the table.

Parameters:

modelElement - the table to be rendered by this renderer

rowRange - the table rows to be rendered

TableRenderer

public TableRenderer(Table modelElement)

Creates a TableRenderer from a Table.

Parameters:

modelElement - the table to be rendered by this renderer

Method Detail

addChild

public void addChild(IRenderer renderer)

Description copied from interface: IRenderer

Adds a child to the current renderer

Specified by:

addChild in interface IRenderer

Overrides:

addChild in class AbstractRenderer

Parameters:

renderer - a child to be added

layout

public LayoutResult layout(LayoutContext layoutContext)

Description copied from interface: IRenderer

This method simulates positioning of the renderer, including all of its children, and returns the LayoutResult, representing the layout result, including occupied area, status, i.e. if there was enough place to fit the renderer subtree, etc. LayoutResult can be extended to return custom layout results for custom elements, e.g. TextRenderer uses TextLayoutResult as its result. This method can be called standalone to learn how much area the renderer subtree needs, or can be called before IRenderer.draw(DrawContext), to prepare the renderer to be flushed to the output stream.

Parameters:

layoutContext - the description of layout area and any other additional information

Returns:

result of the layout process

draw

public void draw(DrawContext drawContext)

Description copied from interface: IRenderer

Flushes the renderer subtree contents, i.e. draws itself on canvas, adds necessary objects to the PdfDocument etc.

Specified by:

draw in interface IRenderer

Overrides:

draw in class AbstractRenderer

Parameters:

drawContext - contains the PdfDocument to which the renderer subtree if flushed, the PdfCanvas on which the renderer subtree is drawn and other additional parameters needed to perform drawing

drawChildren

public void drawChildren(DrawContext drawContext)

Description copied from class: AbstractRenderer

Performs the drawing operation for all children of this renderer.

Overrides:

drawChildren in class AbstractRenderer

Parameters:

drawContext - the context (canvas, document, etc) of this drawing operation.

getNextRenderer

public IRenderer getNextRenderer()

Description copied from interface: IRenderer

Gets a new instance of this class to be used as a next renderer, after this renderer is used, if IRenderer.layout(LayoutContext) is called more than once.

Returns:

new renderer instance

move

public void move(float dxRight,
                 float dyUp)

Description copied from interface: IRenderer

Moves the renderer subtree by the specified offset. This method affects occupied area of the renderer.

Specified by:

move in interface IRenderer

Overrides:

move in class AbstractRenderer

Parameters:

dxRight - the x-axis offset in points. Positive value will move the renderer subtree to the right.

dyUp - the y-axis offset in points. Positive value will move the renderer subtree to the top.

calculateScaledColumnWidths

protected float[] calculateScaledColumnWidths(Table tableModel,
                                              float tableWidth)

split

protected TableRenderer[] split(int row)

split

protected TableRenderer[] split(int row,
                                boolean hasContent)

createSplitRenderer

protected TableRenderer createSplitRenderer(Table.RowRange rowRange)

createOverflowRenderer

protected TableRenderer createOverflowRenderer(Table.RowRange rowRange)

drawBorders

protected void drawBorders(DrawContext drawContext)
