Field Details

mBean

protected StringBean mBean
The underlying bean that provides our htmlparser specific properties.

Constructor Details

HTMLTextBean

public HTMLTextBean()
Creates a new HTMLTextBean. This uses an underlying StringBean and displays the text.

Method Details

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)
Add a PropertyChangeListener to the listener list. The listener is registered for all properties.

Delegates to the underlying StringBean

Parameters:
listener - The PropertyChangeListener to be added.

Returns:
The StringBean this bean uses to fetch text.

getCollapse

public boolean getCollapse()
Get the current 'collapse whitespace' state. If set to true this emulates the operation of browsers in interpretting text where auser agents should collapse input white space sequences when producing output inter-word space.

getConnection

public URLConnection getConnection()
Getter for property Connection.
Returns:
Value of property Connection.

getLinks

public boolean getLinks()
Getter for property links.

Delegates to the underlying StringBean

Returns:
Value of property links.

getMinimumSize

public Dimension getMinimumSize()
Return the minimum dimension for this visible bean.
Returns:
a minimum bounding box for this bean.

getReplaceNonBreakingSpaces

public boolean getReplaceNonBreakingSpaces()
Get the current 'replace non breaking spaces' state.
Returns:
The true if non-breaking spaces (character '\u00a0', numeric character reference &160; or character entity reference  ) are to be replaced with normal spaces (character '\u0020').
