BasicTextAreaUI (Java Platform SE 6) (original) (raw)
javax.swing.plaf.basic
Class BasicTextAreaUI
java.lang.Object
javax.swing.plaf.ComponentUI
javax.swing.plaf.TextUI
javax.swing.plaf.basic.BasicTextUI
javax.swing.plaf.basic.BasicTextAreaUI
All Implemented Interfaces:
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.beans package. Please see XMLEncoder.

BasicTextAreaUI
public BasicTextAreaUI()
Constructs a new BasicTextAreaUI object.
| Method Detail |
|---|
createUI
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:
[getPropertyPrefix](../../../../javax/swing/plaf/basic/BasicTextUI.html#getPropertyPrefix%28%29) in class [BasicTextUI](../../../../javax/swing/plaf/basic/BasicTextUI.html "class in javax.swing.plaf.basic")
Returns:
the name ("TextArea")
installDefaults
protected void installDefaults()
Description copied from class: [BasicTextUI](../../../../javax/swing/plaf/basic/BasicTextUI.html#installDefaults%28%29)
Initializes component properties, e.g. font, foreground, background, caret color, selection color, selected text color, disabled text color, and border color. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.
Overrides:
[installDefaults](../../../../javax/swing/plaf/basic/BasicTextUI.html#installDefaults%28%29) in class [BasicTextUI](../../../../javax/swing/plaf/basic/BasicTextUI.html "class in javax.swing.plaf.basic")
See Also:
BasicTextUI.uninstallDefaults(), BasicTextUI.installUI(javax.swing.JComponent)
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:
[propertyChange](../../../../javax/swing/plaf/basic/BasicTextUI.html#propertyChange%28java.beans.PropertyChangeEvent%29) in class [BasicTextUI](../../../../javax/swing/plaf/basic/BasicTextUI.html "class in javax.swing.plaf.basic")
Parameters:
evt - the property change event
getPreferredSize
public Dimension getPreferredSize(JComponent c)
The method is overridden to take into account caret width.
Overrides:
[getPreferredSize](../../../../javax/swing/plaf/basic/BasicTextUI.html#getPreferredSize%28javax.swing.JComponent%29) in class [BasicTextUI](../../../../javax/swing/plaf/basic/BasicTextUI.html "class in javax.swing.plaf.basic")
Parameters:
c - the editor component
Returns:
the preferred size
Throws:
[IllegalArgumentException](../../../../java/lang/IllegalArgumentException.html "class in java.lang") - 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:
[getMinimumSize](../../../../javax/swing/plaf/basic/BasicTextUI.html#getMinimumSize%28javax.swing.JComponent%29) in class [BasicTextUI](../../../../javax/swing/plaf/basic/BasicTextUI.html "class in javax.swing.plaf.basic")
Parameters:
c - the editor component
Returns:
the minimum size
Throws:
[IllegalArgumentException](../../../../java/lang/IllegalArgumentException.html "class in java.lang") - if invalid value is passed
Since:
1.5
See Also:
JComponent.getMinimumSize(), LayoutManager.minimumLayoutSize(java.awt.Container), ComponentUI.getPreferredSize(javax.swing.JComponent)
create
public View create(Element elem)
Creates the view for an element. Returns a WrappedPlainView or PlainView.
Specified by:
[create](../../../../javax/swing/text/ViewFactory.html#create%28javax.swing.text.Element%29) in interface [ViewFactory](../../../../javax/swing/text/ViewFactory.html "interface in javax.swing.text")
Overrides:
[create](../../../../javax/swing/plaf/basic/BasicTextUI.html#create%28javax.swing.text.Element%29) in class [BasicTextUI](../../../../javax/swing/plaf/basic/BasicTextUI.html "class in javax.swing.plaf.basic")
Parameters:
elem - the element
Returns:
the view
See Also:
getBaseline
public int getBaseline(JComponent c, int width, int height)
Returns the baseline.
Overrides:
[getBaseline](../../../../javax/swing/plaf/ComponentUI.html#getBaseline%28javax.swing.JComponent, int, int%29) in class [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")
Parameters:
c - JComponent baseline 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](../../../../java/lang/NullPointerException.html "class in java.lang") - if c is null
[IllegalArgumentException](../../../../java/lang/IllegalArgumentException.html "class in java.lang") - if width or height is < 0
Since:
1.6
See Also:
[JComponent.getBaseline(int, int)](../../../../javax/swing/JComponent.html#getBaseline%28int, int%29)
getBaselineResizeBehavior
public Component.BaselineResizeBehavior getBaselineResizeBehavior(JComponent c)
Returns an enum indicating how the baseline of the component changes as the size changes.
Overrides:
[getBaselineResizeBehavior](../../../../javax/swing/plaf/ComponentUI.html#getBaselineResizeBehavior%28javax.swing.JComponent%29) in class [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")
Parameters:
c - JComponent to return baseline resize behavior for
Returns:
an enum indicating how the baseline changes as the component size changes
Throws:
[NullPointerException](../../../../java/lang/NullPointerException.html "class in java.lang") - if c is null
Since:
1.6
