 View v)

Constructor

Parameters:

f - factory

v - root view

Method Details

get

public static HTMLRenderer get(String html)

Get View from HTML String

Parameters:

html - html string

Returns:

renderer view

getWidth

public float getWidth()

Get Width

Returns:

width

getHeight

public float getHeight()

Get Height

Returns:

height

getHeightOneLine

public float getHeightOneLine()

Get Height for one line

Returns:

height

setAllocation

public void setAllocation(int width,
 int height)

Set Allocation (actual print size)

Parameters:

width - actual print width

height - actual print height

setAllocation

public void setAllocation(Rectangle allocation)

Set Allocation (actual size)

Parameters:

allocation - actual print size

getAllocation

public Rectangle getAllocation()

Get Allocation

Returns:

actual print size or if not defined the renderer size

getAttributes

public AttributeSet getAttributes()

Fetches the attributes to use when rendering. At the root level there are no attributes. If an attribute is resolved up the view hierarchy this is the end of the line.

Overrides:

getAttributes in class View

Returns:

attribute set

getPreferredSpan

public float getPreferredSpan(int axis)

Determines the preferred span for this view along an axis.

Specified by:

getPreferredSpan in class View

Parameters:

axis - may be either X_AXIS or Y_AXIS

Returns:

the span the view would like to be rendered into. Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.

getMinimumSpan

public float getMinimumSpan(int axis)

Determines the minimum span for this view along an axis.

Overrides:

getMinimumSpan in class View

Parameters:

axis - may be either X_AXIS or Y_AXIS

Returns:

the span the view would like to be rendered into. Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.

getMaximumSpan

public float getMaximumSpan(int axis)

Determines the maximum span for this view along an axis.

Overrides:

getMaximumSpan in class View

Parameters:

axis - may be either X_AXIS or Y_AXIS

Returns:

the span the view would like to be rendered into. Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.

getAlignment

public float getAlignment(int axis)

Determines the desired alignment for this view along an axis.

Overrides:

getAlignment in class View

Parameters:

axis - may be either X_AXIS or Y_AXIS

Returns:

the desired alignment, where 0.0 indicates the origin and 1.0 the full span away from the origin

paint

public void paint(Graphics g,
 Shape allocation)

Renders the view.

Specified by:

paint in class View

Parameters:

g - the graphics context

allocation - the region to render into

setParent

public void setParent(View parent)

Sets the view parent.

Overrides:

setParent in class View

Parameters:

parent - the parent view

getViewCount

public int getViewCount()

Returns the number of views in this view. Since this view simply wraps the root of the view hierarchy it has exactly one child.

Overrides:

getViewCount in class View

Returns:

the number of views

See Also:

• getView(int)

getView

public View getView(int n)

Gets the n-th view in this container.

Overrides:

getView in class View

Parameters:

n - the number of the view to get

Returns:

the view

modelToView

public Shape modelToView(int pos,
 Shape a,
 Position.Bias b)
                  throws BadLocationException

Provides a mapping from the document model coordinate space to the coordinate space of the view mapped to it.

Specified by:

modelToView in class View

Parameters:

pos - the position to convert

a - the allocated region to render into

b - position

Returns:

the bounding box of the given position

Throws:

BadLocationException

modelToView

public Shape modelToView(int p0,
 Position.Bias b0,
 int p1,
 Position.Bias b1,
 Shape a)
                  throws BadLocationException

Provides a mapping from the document model coordinate space to the coordinate space of the view mapped to it.

Overrides:

modelToView in class View

Parameters:

p0 - the position to convert >= 0

b0 - the bias toward the previous character or the next character represented by p0, in case the position is a boundary of two views.

p1 - the position to convert >= 0

b1 - the bias toward the previous character or the next character represented by p1, in case the position is a boundary of two views.

a - the allocated region to render into

Returns:

the bounding box of the given position is returned

Throws:

BadLocationException - if the given position does not represent a valid location in the associated document

IllegalArgumentException - for an invalid bias argument
