Class SynthLookAndFeel

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.

    • 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

      public UIDefaults getDefaults()
      Returns the defaults for this SynthLookAndFeel.
      Overrides:
      getDefaults in class BasicLookAndFeel
      Returns:
      Defaults table.

    • isSupportedLookAndFeel

      public boolean isSupportedLookAndFeel()
      Returns true, SynthLookAndFeel is always supported.
      Specified by:
      isSupportedLookAndFeel in class LookAndFeel
      Returns:
      true.

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)
