Constructor Detail

CellRenderer

public CellRenderer(Cell modelElement)

Creates a CellRenderer from its corresponding layout object.

Parameters:

modelElement - the Cell which this object should manage

Method Detail

getModelElement

public IPropertyContainer getModelElement()

Gets the model element associated with this renderer.

Specified by:

getModelElement in interface IRenderer

Overrides:

getModelElement in class AbstractRenderer

Returns:

the model element, as a container of properties

retrieveWidth

protected Float retrieveWidth(float parentBoxWidth)

Description copied from class: AbstractRenderer

Retrieves element's fixed content box width, if it's set. Takes into account Property.BOX_SIZING, Property.MIN_WIDTH, and Property.MAX_WIDTH properties.

Overrides:

retrieveWidth in class AbstractRenderer

Parameters:

parentBoxWidth - width of the parent element content box. If element has relative width, it will be calculated relatively to this parameter.

Returns:

element's fixed content box width or null if it's not set.

AbstractRenderer.hasAbsoluteUnitValue(int)

createSplitRenderer

protected AbstractRenderer createSplitRenderer(int layoutResult)

Overrides:

createSplitRenderer in class BlockRenderer

createOverflowRenderer

protected AbstractRenderer createOverflowRenderer(int layoutResult)

Overrides:

createOverflowRenderer in class BlockRenderer

drawBackground

public void drawBackground(DrawContext drawContext)

Description copied from class: AbstractRenderer

Draws a background layer if it is defined by a key Property.BACKGROUND in either the layout element or this IRenderer itself.

Overrides:

drawBackground in class AbstractRenderer

Parameters:

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

drawBorder

public void drawBorder(DrawContext drawContext)

Performs the drawing operation for the border of this renderer, if defined by any of the Property.BORDER values in either the layout element or this IRenderer itself.

Overrides:

drawBorder in class AbstractRenderer

Parameters:

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

applyBorderBox

protected Rectangle applyBorderBox(Rectangle rect,
                                   Border[] borders,
                                   boolean reverse)

Description copied from class: AbstractRenderer

Applies the given border box (borders) on the given rectangle

Overrides:

applyBorderBox in class AbstractRenderer

Parameters:

rect - a rectangle paddings will be applied on.

borders - the borders to be applied on the given rectangle

reverse - indicates whether the border box will be applied inside (in case of false) or outside (in case of false) the rectangle.

Returns:

a border box of the renderer

applyMargins

protected Rectangle applyMargins(Rectangle rect,
                                 UnitValue[] margins,
                                 boolean reverse)

Description copied from class: AbstractRenderer

Applies given margins on the given rectangle

Overrides:

applyMargins in class AbstractRenderer

Parameters:

rect - a rectangle margins will be applied on.

margins - the margins to be applied on the given rectangle

reverse - indicates whether margins will be applied inside (in case of false) or outside (in case of true) the rectangle.

Returns:

a border box of the renderer

applySpacings

protected Rectangle applySpacings(Rectangle rect,
                                  boolean reverse)

applySpacings

protected Rectangle applySpacings(Rectangle rect,
                                  float[] spacings,
                                  boolean reverse)

getNextRenderer

public IRenderer getNextRenderer()

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
