BasicButtonUI
public BasicButtonUI()
createUI
public static ComponentUI createUI(JComponent c)
-
getPropertyPrefix
protected String getPropertyPrefix()
-
installUI
public void installUI(JComponent c)
-
Description copied from class:
ComponentUI
-
Configures the specified component appropriate 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:
-
Install any 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.
-
Install a LayoutManager on the component if necessary.
-
Create/add any required sub-components to the component.
-
Create/install event listeners on the component.
-
Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately.
-
Install keyboard UI (mnemonics, traversal, etc.) on the component.
-
Initialize any appropriate instance data.
-
-
Overrides:
-
installUI
in class
ComponentUI
-
-
Parameters:
-
c - the component where this UI delegate is being installed
-

-
installListeners
protected void installListeners(AbstractButton b)
-
installKeyboardActions
protected void installKeyboardActions(AbstractButton b)
-
uninstallUI
public void uninstallUI(JComponent c)
-
Description copied from class:
ComponentUI
-
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:
-
Remove any UI-set borders from the component.
-
Remove any UI-set layout managers on the component.
-
Remove any UI-added sub-components from the component.
-
Remove any UI-added event/property listeners from the component.
-
Remove any UI-installed keyboard UI from the component.
-
Nullify any allocated instance data objects to allow for GC.
-
-
Overrides:
-
uninstallUI
in class
ComponentUI
-
-
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
-

getDefaultTextIconGap
public int getDefaultTextIconGap(AbstractButton b)
-
paint
public void paint(Graphics g,
JComponent c)
-
Description copied from class:
ComponentUI
-
Paints the specified component appropriate for the look and feel. This method is invoked from the ComponentUI.update method when the specified component is being painted. Subclasses should override this method and use the specified Graphics object to render the content of the component.
-
-
Overrides:
-
paint
in class
ComponentUI
-
-
Parameters:
-
g - the Graphics context in which to paint
-
c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
-
See Also:
-
ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)
paintIcon
protected void paintIcon(Graphics g,
JComponent c,
Rectangle iconRect)
-
paintText
protected void paintText(Graphics g,
JComponent c,
Rectangle textRect,
String text)
-
As of Java 2 platform v 1.4 this method should not be used or overriden. Use the paintText method which takes the AbstractButton argument.
-
paintText
protected void paintText(Graphics g,
AbstractButton b,
Rectangle textRect,
String text)
-
Method which renders the text of the current button.
-
-
Parameters:
-
g - Graphics context
-
b - Current button to render
-
textRect - Bounding rectangle to render the text.
-
text - String to render
-
Since:
-
1.4

getMinimumSize
public Dimension getMinimumSize(JComponent c)
-
Description copied from class:
ComponentUI
-
Returns the specified component's minimum size appropriate for the look and feel. If null is returned, the minimum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokes getPreferredSize and returns that value.
-
-
Overrides:
-
getMinimumSize
in class
ComponentUI
-
-
Parameters:
-
c - the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
-
Returns:
-
a Dimension object or null
-
See Also:
-
JComponent.getMinimumSize()

,
ComponentUI.getPreferredSize(javax.swing.JComponent)
getPreferredSize
public Dimension getPreferredSize(JComponent c)
-
Description copied from class:
ComponentUI
-
Returns the specified component's preferred size appropriate for the look and feel. If null is returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returns null.
-
-
Overrides:
-
getPreferredSize
in class
ComponentUI
-
-
Parameters:
-
c - the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
