org.piccolo2d.PNode

org.piccolo2d.nodes.PHtmlView

All Implemented Interfaces:

Printable, Serializable, Cloneable

public class PHtmlView
extends PNode

PHtmlView is a Piccolo node for rendering HTML text. It uses a JLabel under the hood so you have the same restrictions regarding HTML as you have when using standard Swing components (HTML 3.2 + subset of CSS 1.0).

Since:

1.3

Constructor Detail

PHtmlView

public PHtmlView()

Create an empty HTML text node with the default font and text color.

PHtmlView

public PHtmlView(String text)

Create a HTML text node with the specified HTML text and the default font and text color.

Parameters:

text - HTML text for this HTML text node

PHtmlView

public PHtmlView(String text,
         Font font,
         Color textColor)

Parameters:

text - HTML text for this HTML text node

font - font for this HTML text node

textColor - text color for this HTML text node

Method Detail

getText

public String getText()

Return the HTML text for this HTML text node.

Returns:

the HTML text for this HTML text node

setText

public void setText(String text)

Set the HTML text for this HTML text node to text.

This is a bound property.

Parameters:

text - HTML text for this HTML text node

getFont

public Font getFont()

Return the font for this HTML text node. This font is used to render the HTML text if not otherwise specified via CSS. Defaults to DEFAULT_FONT.

Returns:

the font for this HTML text node

setFont

public void setFont(Font font)

Set the font for this HTML text node to font. This font is used to render the HTML text if not otherwise specified via CSS.

This is a bound property.

Parameters:

font - font for this HTML text node

getTextColor

public Color getTextColor()

Return the text color for this HTML text node. This text color is used to render the HTML text if not otherwise specified via CSS. Defaults to DEFAULT_TEXT_COLOR.

Returns:

the text color for this HTML text node

setTextColor

public void setTextColor(Color textColor)

Set the text color for this HTML text node to textColor. This text color is used to render the HTML text if not otherwise specified via CSS. This is a bound property.

Parameters:

textColor - text color for this HTML text node

setBounds

public boolean setBounds(double x,
                double y,
                double width,
                double height)

Set the bounds of this node to the given position and size. These bounds are stored in the local coordinate system of this node. If the width or height is less then or equal to zero then the bound's empty bit will be set to true. Subclasses must call the super.setBounds() method.

Overrides:

setBounds in class PNode

Parameters:

x - x position of bounds

y - y position of bounds

width - width to apply to the bounds

height - height to apply to the bounds

Returns:

true if the bounds changed.

setBounds

public boolean setBounds(Rectangle2D newBounds)

Set the bounds of this node to the given value. These bounds are stored in the local coordinate system of this node.

Overrides:

setBounds in class PNode

Parameters:

newBounds - bounds to apply to this node

Returns:

true if the bounds changed.

paint

protected void paint(PPaintContext paintContext)

Paint this node behind any of its children nodes. Subclasses that define a different appearance should override this method and paint themselves there.

The HTML text is painted last, so it will appear on top of any child nodes.

Overrides:

paint in class PNode

Parameters:

paintContext - the paint context to use for painting the node

getLinkAddressAt

public String getLinkAddressAt(Point2D point)

Return the address specified in the HTML link at the specified point in this node's local coordinate system, if any.

Parameters:

point - point in this node's local coordinate system

Returns:

the address specified in the HTML link at the specified point in this node's local coordinate system, or null if no such HTML link exists

getLinkAddressAt

public String getLinkAddressAt(double x,
                      double y)

Return the address specified in the HTML link at the specified x and y coordinates in this node's local coordinate system, if any.

Parameters:

x - x coordinate in this node's local coordinate system

y - y coordinate in this node's local coordinate system

Returns:

the address specified in the HTML link at the specified x and y coordinates in this node's local coordinate system, or null if no such HTML link exists
