Constructor Detail

BlockView

public BlockView(Element elem,
                 int axis)

Creates a new view that represents an html box. This can be used for a number of elements.

Parameters:

elem - the element to create a view for

axis - either View.X_AXIS or View.Y_AXIS

Method Detail

calculateMajorAxisRequirements

protected SizeRequirements calculateMajorAxisRequirements(int axis,
                                                          SizeRequirements r)

Calculate the requirements of the block along the major axis (i.e. the axis along with it tiles). This is implemented to provide the superclass behavior and then adjust it if the CSS width or height attribute is specified and applicable to the axis.

Overrides:

calculateMajorAxisRequirements in class BoxView

calculateMinorAxisRequirements

protected SizeRequirements calculateMinorAxisRequirements(int axis,
                                                          SizeRequirements r)

Calculate the requirements of the block along the minor axis (i.e. the axis orthoginal to the axis along with it tiles). This is implemented to provide the superclass behavior and then adjust it if the CSS width or height attribute is specified and applicable to the axis.

Overrides:

calculateMinorAxisRequirements in class BoxView

paint

public void paint(Graphics g,
                  Shape allocation)

Renders using the given rendering surface and area on that surface. This is implemented to delegate to the css box painter to paint the border and background prior to the interior.

Parameters:

g - the rendering surface to use

allocation - the allocated region to render into

Overrides:

paint in class BoxView

See Also:

View.paint(java.awt.Graphics, java.awt.Shape)

getAttributes

public AttributeSet getAttributes()

Fetches the attributes to use when rendering. This is implemented to multiplex the attributes specified in the model with a StyleSheet.

Overrides:

getAttributes in class View

getResizeWeight

public int getResizeWeight(int axis)

Gets the resize weight.

Parameters:

axis - may be either X_AXIS or Y_AXIS

Returns:

the weight

Throws:

IllegalArgumentException - for an invalid axis

Overrides:

getResizeWeight in class BoxView

getAlignment

public float getAlignment(int axis)

Gets the alignment.

Parameters:

axis - may be either X_AXIS or Y_AXIS

Returns:

the alignment

Overrides:

getAlignment in class BoxView

changedUpdate

public void changedUpdate(DocumentEvent changes,
                          Shape a,
                          ViewFactory f)

Overrides:

changedUpdate in class CompositeView

setPropertiesFromAttributes

protected void setPropertiesFromAttributes()

Update any cached values that come from attributes.

getStyleSheet

protected StyleSheet getStyleSheet()
