Constructor Detail

• AbstractColorChooserPanel

  public AbstractColorChooserPanel()

Method Detail

• updateChooser

  public abstract void updateChooser()

  Invoked automatically when the model's state changes. It is also called by installChooserPanel to allow you to set up the initial state of your chooser. Override this method to update your ChooserPanel.

• buildChooser

  protected abstract void buildChooser()

  Builds a new chooser panel.

• getDisplayName

  public abstract String getDisplayName()

  Returns a string containing the display name of the panel.

  Returns:

  the name of the display panel

• getMnemonic

  public int getMnemonic()

  Provides a hint to the look and feel as to the KeyEvent.VK constant that can be used as a mnemonic to access the panel. A return value <= 0 indicates there is no mnemonic.

  The return value here is a hint, it is ultimately up to the look and feel to honor the return value in some meaningful way.

  This implementation returns 0, indicating the AbstractColorChooserPanel does not support a mnemonic, subclasses wishing a mnemonic will need to override this.

  Returns:

  KeyEvent.VK constant identifying the mnemonic; <= 0 for no mnemonic

  getDisplayedMnemonicIndex()

• getDisplayedMnemonicIndex

  public int getDisplayedMnemonicIndex()

  Provides a hint to the look and feel as to the index of the character in getDisplayName that should be visually identified as the mnemonic. The look and feel should only use this if getMnemonic returns a value > 0.

  The return value here is a hint, it is ultimately up to the look and feel to honor the return value in some meaningful way. For example, a look and feel may wish to render each AbstractColorChooserPanel in a JTabbedPane, and further use this return value to underline a character in the getDisplayName.

  This implementation returns -1, indicating the AbstractColorChooserPanel does not support a mnemonic, subclasses wishing a mnemonic will need to override this.

  Returns:

  Character index to render mnemonic for; -1 to provide no visual identifier for this panel.
