Method Detail

* #### createUI  
public static [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf") createUI([JComponent](../../../../javax/swing/JComponent.html "class in javax.swing") c)  
* #### installUI  
public void installUI([JComponent](../../../../javax/swing/JComponent.html "class in javax.swing") c)  
Configures the specified component appropriately for the look and feel. This method is invoked when the `ComponentUI` instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:  
         1. Install default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should _not_ be overridden.  
         2. Install a `LayoutManager` on the component if necessary.  
         3. Create/add any required sub-components to the component.  
         4. Create/install event listeners on the component.  
         5. Create/install a `PropertyChangeListener` on the component in order to detect and respond to component property changes appropriately.  
         6. Install keyboard UI (mnemonics, traversal, etc.) on the component.  
         7. Initialize any appropriate instance data.  
Overrides:  
`[installUI](../../../../javax/swing/plaf/ComponentUI.html#installUI-javax.swing.JComponent-)` in class `[ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")`  
Parameters:  
`c` \- the component where this UI delegate is being installed  
See Also:  
[ComponentUI.uninstallUI(javax.swing.JComponent)](../../../../javax/swing/plaf/ComponentUI.html#uninstallUI-javax.swing.JComponent-), [JComponent.setUI(javax.swing.plaf.ComponentUI)](../../../../javax/swing/JComponent.html#setUI-javax.swing.plaf.ComponentUI-), [JComponent.updateUI()](../../../../javax/swing/JComponent.html#updateUI--)  
* #### uninstallUI  
public void uninstallUI([JComponent](../../../../javax/swing/JComponent.html "class in javax.swing") c)  
Reverses configuration which was done on the specified component during`installUI`. This method is invoked when this`UIComponent` instance is being removed as the UI delegate for the specified component. This method should undo the configuration performed in `installUI`, being careful to leave the `JComponent` instance in a clean state (no extraneous listeners, look-and-feel-specific property objects, etc.). This should include the following:  
         1. Remove any UI-set borders from the component.  
         2. Remove any UI-set layout managers on the component.  
         3. Remove any UI-added sub-components from the component.  
         4. Remove any UI-added event/property listeners from the component.  
         5. Remove any UI-installed keyboard UI from the component.  
         6. Nullify any allocated instance data objects to allow for GC.  
Overrides:  
`[uninstallUI](../../../../javax/swing/plaf/ComponentUI.html#uninstallUI-javax.swing.JComponent-)` in class `[ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")`  
Parameters:  
`c` \- the component from which this UI delegate is being removed; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

* #### installDefaults  
protected void installDefaults([JPanel](../../../../javax/swing/JPanel.html "class in javax.swing") p)  
* #### uninstallDefaults  
protected void uninstallDefaults([JPanel](../../../../javax/swing/JPanel.html "class in javax.swing") p)  
* #### getBaseline  
public int getBaseline([JComponent](../../../../javax/swing/JComponent.html "class in javax.swing") c,  
                       int width,  
                       int height)  
Returns the baseline.  
Overrides:  
`[getBaseline](../../../../javax/swing/plaf/ComponentUI.html#getBaseline-javax.swing.JComponent-int-int-)` 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

* #### getBaselineResizeBehavior  
public [Component.BaselineResizeBehavior](../../../../java/awt/Component.BaselineResizeBehavior.html "enum in java.awt") getBaselineResizeBehavior([JComponent](../../../../javax/swing/JComponent.html "class in javax.swing") c)  
Returns an enum indicating how the baseline of the component changes as the size changes.  
Overrides:  
`[getBaselineResizeBehavior](../../../../javax/swing/plaf/ComponentUI.html#getBaselineResizeBehavior-javax.swing.JComponent-)` 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
