All Implemented Interfaces:

Serializable

Direct Known Subclasses:

NimbusLookAndFeel

public class SynthLookAndFeel
extends BasicLookAndFeel

SynthLookAndFeel provides the basis for creating a customized look and feel. SynthLookAndFeel does not directly provide a look, all painting is delegated. You need to either provide a configuration file, by way of the load(java.io.InputStream, java.lang.Class<?>) method, or provide your own SynthStyleFactory to setStyleFactory(javax.swing.plaf.synth.SynthStyleFactory). Refer to the package summary for an example of loading a file, and SynthStyleFactory for an example of providing your own SynthStyleFactory to setStyleFactory.

SynthIcon interface provides paintIcon(synthContext, graphics, x, y, width, height) method that allows to draw the icon with the given SynthContext.

Warning: This class implements Serializable as a side effect of it extending BasicLookAndFeel. It is not intended to be serialized. An attempt to serialize it will result in NotSerializableException.

Constructor Details

SynthLookAndFeel

public SynthLookAndFeel()

Creates a SynthLookAndFeel.

For the returned SynthLookAndFeel to be useful you need to invoke load to specify the set of SynthStyles, or invoke setStyleFactory.

See Also:

• load(java.io.InputStream, java.lang.Class<?>)
• setStyleFactory(javax.swing.plaf.synth.SynthStyleFactory)

Method Details

setStyleFactory

public static void setStyleFactory(SynthStyleFactory cache)

Sets the SynthStyleFactory that the UI classes provided by synth will use to obtain a SynthStyle.

Parameters:

cache - SynthStyleFactory the UIs should use.

getStyleFactory

public static SynthStyleFactory getStyleFactory()

Returns the current SynthStyleFactory.

Returns:

SynthStyleFactory

getStyle

public static SynthStyle getStyle(JComponent c,
 Region region)

Gets a SynthStyle for the specified region of the specified component. This is not for general consumption, only custom UIs should call this method.

Parameters:

c - JComponent to get the SynthStyle for

region - Identifies the region of the specified component

Returns:

SynthStyle to use.

updateStyles

public static void updateStyles(Component c)

Updates the style associated with c, and all its children. This is a lighter version of SwingUtilities.updateComponentTreeUI.

Parameters:

c - Component to update style for.

getRegion

public static Region getRegion(JComponent c)

Returns the Region for the JComponent c.

Parameters:

c - JComponent to fetch the Region for

Returns:

Region corresponding to c

createUI

public static ComponentUI createUI(JComponent c)

Creates the Synth look and feel ComponentUI for the passed in JComponent.

Parameters:

c - JComponent to create the ComponentUI for

Returns:

ComponentUI to use for c

load

public void load(InputStream input,
 Class<?> resourceBase)
          throws ParseException

Loads the set of SynthStyles that will be used by this SynthLookAndFeel. resourceBase is used to resolve any path based resources, for example an Image would be resolved by resourceBase.getResource(path). Refer to Synth File Format for more information.

Parameters:

input - InputStream to load from

resourceBase - used to resolve any images or other resources

Throws:

ParseException - if there is an error in parsing

IllegalArgumentException - if input or resourceBase is null

load

public void load(URL url)
          throws ParseException,
IOException

Loads the set of SynthStyles that will be used by this SynthLookAndFeel. Path based resources are resolved relatively to the specified URL of the style. For example an Image would be resolved by new URL(synthFile, path). Refer to Synth File Format for more information.

Parameters:

url - the URL to load the set of SynthStyle from

Throws:

ParseException - if there is an error in parsing

IllegalArgumentException - if synthSet is null

IOException - if synthSet cannot be opened as an InputStream

initialize

public void initialize()

Called by UIManager when this look and feel is installed.

Overrides:

initialize in class LookAndFeel

See Also:

• LookAndFeel.uninitialize()
• UIManager.setLookAndFeel(javax.swing.LookAndFeel)

uninitialize

public void uninitialize()

Called by UIManager when this look and feel is uninstalled.

Overrides:

uninitialize in class LookAndFeel

See Also:

• LookAndFeel.initialize()
• UIManager.setLookAndFeel(javax.swing.LookAndFeel)

getDefaults

public UIDefaults getDefaults()

Returns the defaults for this SynthLookAndFeel.

Overrides:

getDefaults in class BasicLookAndFeel

Returns:

Defaults table.

See Also:

• BasicLookAndFeel.initClassDefaults(javax.swing.UIDefaults)
• BasicLookAndFeel.initSystemColorDefaults(javax.swing.UIDefaults)
• BasicLookAndFeel.initComponentDefaults(javax.swing.UIDefaults)

isSupportedLookAndFeel

public boolean isSupportedLookAndFeel()

Returns true, SynthLookAndFeel is always supported.

Specified by:

isSupportedLookAndFeel in class LookAndFeel

Returns:

true.

See Also:

• UIManager.setLookAndFeel(javax.swing.LookAndFeel)

isNativeLookAndFeel

public boolean isNativeLookAndFeel()

Returns false, SynthLookAndFeel is not a native look and feel.

Specified by:

isNativeLookAndFeel in class LookAndFeel

Returns:

false

getDescription

public String getDescription()

Returns a textual description of SynthLookAndFeel.

Specified by:

getDescription in class LookAndFeel

Returns:

textual description of synth.

getName

public String getName()

Return a short string that identifies this look and feel.

Specified by:

getName in class LookAndFeel

Returns:

a short string identifying this look and feel.

getID

public String getID()

Return a string that identifies this look and feel.

Specified by:

getID in class LookAndFeel

Returns:

a short string identifying this look and feel.

shouldUpdateStyleOnAncestorChanged

public boolean shouldUpdateStyleOnAncestorChanged()

Returns whether or not the UIs should update their SynthStyles from the SynthStyleFactory when the ancestor of the JComponent changes. A subclass that provided a SynthStyleFactory that based the return value from getStyle off the containment hierarchy would override this method to return true.

Returns:

whether or not the UIs should update their SynthStyles from the SynthStyleFactory when the ancestor changed.

shouldUpdateStyleOnEvent

protected boolean shouldUpdateStyleOnEvent(PropertyChangeEvent ev)

Returns whether or not the UIs should update their styles when a particular event occurs.

Parameters:

ev - a PropertyChangeEvent

Returns:

whether or not the UIs should update their styles
