    • getDisplayName

      public String getDisplayName()
      Specified by:
      getDisplayName in class AbstractColorChooserPanel

    • 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 looks up the value from the default ColorChooser.rgbMnemonic, or if it isn't available (or not an Integer) returns -1. The lookup for the default is done through the UIManager: UIManager.get("ColorChooser.rgbMnemonic");.

      Overrides:
      getMnemonic in class AbstractColorChooserPanel
      Returns:
      KeyEvent.VK constant identifying the mnemonic; <= 0 for no mnemonic
      Since:
      1.4

    • 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 looks up the value from the default ColorChooser.rgbDisplayedMnemonicIndex, or if it isn't available (or not an Integer) returns -1. The lookup for the default is done through the UIManager: UIManager.get("ColorChooser.rgbDisplayedMnemonicIndex");.

      Overrides:
      getDisplayedMnemonicIndex in class AbstractColorChooserPanel
      Returns:
      Character index to render mnemonic for; -1 to provide no visual identifier for this panel.

      1.4
