 public class BasicTextAreaUI extends BasicTextUI Provides the look and feel for a plain text editor. In this implementation the default UI is extended to act as a simple view factory.Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beanspackage. Please seeXMLEncoder.

Method Detail- 
createUIpublic static ComponentUI createUI(JComponent ta) Creates a UI for a JTextArea.- Parameters:
- ta- a text area
- Returns:
- the UI
 
 - 
getPropertyPrefixprotected String getPropertyPrefix() Fetches the name used as a key to look up properties through the UIManager. This is used as a prefix to all the standard text properties.- Specified by:
- getPropertyPrefixin class- BasicTextUI
- Returns:
- the name ("TextArea")
 
 - 
propertyChangeprotected void propertyChange(PropertyChangeEvent evt) This method gets called when a bound property is changed on the associated JTextComponent. This is a hook which UI implementations may change to reflect how the UI displays bound properties of JTextComponent subclasses. This is implemented to rebuild the View when the WrapLine or the WrapStyleWord property changes.- Overrides:
- propertyChangein class- BasicTextUI
- Parameters:
- evt- the property change event
 
 - 
getPreferredSizepublic Dimension getPreferredSize(JComponent c) The method is overridden to take into account caret width.- Overrides:
- getPreferredSizein class- BasicTextUI
- Parameters:
- c- the editor component
- Returns:
- the preferred size
- Throws:
- IllegalArgumentException- if invalid value is passed
- Since:
- 1.5
- See Also:
- JComponent.getPreferredSize(),- LayoutManager.preferredLayoutSize(java.awt.Container)
 
 - 
getMinimumSizepublic Dimension getMinimumSize(JComponent c) The method is overridden to take into account caret width.- Overrides:
- getMinimumSizein class- BasicTextUI
- Parameters:
- c- the editor component
- Returns:
- the minimum size
- Throws:
- IllegalArgumentException- if invalid value is passed
- Since:
- 1.5
- See Also:
- JComponent.getMinimumSize(),- LayoutManager.minimumLayoutSize(java.awt.Container),- ComponentUI.getPreferredSize(javax.swing.JComponent)
 
 - 
createpublic View create(Element elem) Creates the view for an element. Returns a WrappedPlainView or PlainView.- Specified by:
- createin interface- ViewFactory
- Overrides:
- createin class- BasicTextUI
- Parameters:
- elem- the element
- Returns:
- the view
- See Also:
- View
 
 - 
getBaselinepublic int getBaseline(JComponent c, int width, int height) Returns the baseline.- Overrides:
- getBaselinein class- ComponentUI
- Parameters:
- c-- JComponentbaseline is being requested for
- width- the width to get the baseline for
- height- the height to get the baseline for
- Returns:
- baseline or a value < 0 indicating there is no reasonable baseline
- Throws:
- NullPointerException- if- cis- null
- IllegalArgumentException- if width or height is < 0
- Since:
- 1.6
- See Also:
- JComponent.getBaseline(int, int)
 
 - 
getBaselineResizeBehaviorpublic Component.BaselineResizeBehavior getBaselineResizeBehavior(JComponent c) Returns an enum indicating how the baseline of the component changes as the size changes.- Overrides:
- getBaselineResizeBehaviorin class- ComponentUI
- Parameters:
- c-- JComponentto return baseline resize behavior for
- Returns:
- an enum indicating how the baseline changes as the component size changes
- Throws:
- NullPointerException- if- cis- null
- Since:
- 1.6
- See Also:
- JComponent.getBaseline(int, int)
