@JavaBean(defaultProperty="UI", description="A component that displays a short string and an icon.") public class JLabel extends JComponent implements SwingConstants, Accessible
A display area for a short text string or an image, or both. A label does not react to input events. As a result, it cannot get the keyboard focus. A label can, however, display a keyboard alternative as a convenience for a nearby component that has a keyboard alternative but can't display it.

A `JLabel` object can display either text, an image, or both. You can specify where in the label's display area the label's contents are aligned by setting the vertical and horizontal alignment. By default, labels are vertically centered in their display area. Text-only labels are leading edge aligned, by default; image-only labels are horizontally centered, by default.

You can also specify the position of the text relative to the image. By default, text is on the trailing edge of the image, with the text and image vertically aligned.

A label's leading and trailing edge are determined from the value of its `ComponentOrientation` property. At present, the default ComponentOrientation setting maps the leading edge to left and the trailing edge to right.

Finally, you can use the `setIconTextGap` method to specify how many pixels should appear between the text and the image. The default is 4 pixels.

See How to Use Labels in The Java Tutorial for further documentation.

Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the `java.beans` package. Please see `XMLEncoder`.

  1.2

See Also:
  - `setDisabledIcon(Icon)`
  - `LookAndFeel.getDisabledIcon(JComponent, Icon)`
  - `ImageIcon`

### setDisabledIcon

@BeanProperty(visualUpdate=true, description="The icon to display if the label is disabled.") public void setDisabledIcon(Icon disabledIcon)
Set the icon to be displayed if this JLabel is "disabled" (JLabel.setEnabled(false)).

Parameters:
  `disabledIcon` - the Icon to display when the component is disabled
See Also:
  - `getDisabledIcon()`
  - `JComponent.setEnabled(boolean)`

### setDisplayedMnemonic

@BeanProperty(visualUpdate=true, description="The mnemonic keycode.") public void setDisplayedMnemonic(int key)
Specify a keycode that indicates a mnemonic key. This property is used when the label is part of a larger component. If the labelFor property of the label is not null, the label will call the requestFocus method of the component specified by the labelFor property when the mnemonic is activated.

Parameters:
  `key` - a keycode that indicates a mnemonic key
See Also:
  - `getLabelFor()`
  - `setLabelFor(Component)`

### setDisplayedMnemonic

public void setDisplayedMnemonic(char aChar)
Specifies the displayedMnemonic as a char value.

Parameters:
  `aChar` - a char specifying the mnemonic to display
See Also:
  - `setDisplayedMnemonic(int)`

### getDisplayedMnemonic

public int getDisplayedMnemonic()
Return the keycode that indicates a mnemonic key. This property is used when the label is part of a larger component. If the labelFor property of the label is not null, the label will call the requestFocus method of the component specified by the labelFor property when the mnemonic is activated.

Returns:
  int value for the mnemonic key
See Also:
  - `getLabelFor()`
  - `setLabelFor(Component)`

### setDisplayedMnemonicIndex

@BeanProperty(visualUpdate=true, description="the index into the String to draw the keyboard character mnemonic at") public void setDisplayedMnemonicIndex(int index) throws IllegalArgumentException
Provides a hint to the look and feel as to which character in the text should be decorated to represent the mnemonic. Not all look and feels may support this. A value of -1 indicates either there is no mnemonic, the mnemonic character is not contained in the string, or the developer does not wish the mnemonic to be displayed.

The value of this is updated as the properties relating to the mnemonic change (such as the mnemonic itself, the text...). You should only ever have to call this if you do not wish the default character to be underlined. For example, if the text was 'Save As', with a mnemonic of 'a', and you wanted the 'A' to be decorated, as 'Save As', you would have to invoke `setDisplayedMnemonicIndex(5)` after invoking `setDisplayedMnemonic(KeyEvent.VK_A)`.

Parameters:
  `index` - Index into the String to underline
Throws:
  `IllegalArgumentException` - will be thrown if `index` is >= length of the text, or < -1
Since:
  1.4

### getDisplayedMnemonicIndex

public int getDisplayedMnemonicIndex()
Returns the character, as an index, that the look and feel should provide decoration for as representing the mnemonic character.

Returns:
  index representing mnemonic character
Since:
  1.4
See Also:
  - `setDisplayedMnemonicIndex(int)`

### checkHorizontalKey
