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 JavaBeansTM has been added to the
java.beanspackage. Please seeXMLEncoder.

public static ComponentUI createUI(JComponent ta)
Creates a UI for a JTextArea.- Parameters:
ta- a text area- Returns:
- the UI

getPropertyPrefix
protected 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 classBasicTextUI- Returns:
- the name ("TextArea")
-
installDefaults
protected void installDefaults()
Description copied from class:BasicTextUIInitializes component properties, such as font, foreground, background, caret color, selection color, selected text color, disabled text color, and border color.

-
propertyChange
protected 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 classBasicTextUI- Parameters:
evt- the property change event
-
getPreferredSize
public Dimension getPreferredSize(JComponent c)
The method is overridden to take into account caret width.- Overrides:
getPreferredSizein classBasicTextUI- 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)
-
getMinimumSize
public Dimension getMinimumSize(JComponent c)
The method is overridden to take into account caret width.- Overrides:
getMinimumSizein classBasicTextUI- Parameters:
c- the editor component- Returns:
- the minimum size
- Throws:
IllegalArgumentException- if invalid value is passed- Since:
- 1.5
- See Also:

getBaselineResizeBehavior
public Component.BaselineResizeBehavior getBaselineResizeBehavior(JComponent c)
Returns an enum indicating how the baseline of the component changes as the size changes.- Overrides:
getBaselineResizeBehaviorin classComponentUI- Parameters:
c-JComponentto return baseline resize behavior for- Returns:
- an enum indicating how the baseline changes as the component size changes
- Throws:
