Shows how to specify horizontal and vertical alignment as well as how to align a label's text and image. The following table lists some of the many examples that use labels. Sets or gets which component the label describes. Sets or gets the number of pixels between the label's text and its image. For vertical position: TOP, CENTER (the default), and BOTTOM. SwingConstants interface defines five possible values for horizontal position: LEADING, LEFT, CENTER, RIGHT, and TRAILING (the default). Sets or gets the location where the label's text will be placed, relative to the label's image. For vertical alignment: TOP, CENTER (the default), and BOTTOM. SwingConstants interface defines five possible values for horizontal alignment: LEFT, CENTER (the default for image-only labels), RIGHT, LEADING (the default for text-only labels), TRAILING. Sets or gets the area on the label where its contents should be placed. If you do not specify a disabled image, then the look and feel creates one by manipulating the default image.ДЇine Tuning the Label's Appearance Method Sets or gets the image displayed by the label when it is disabled. Not all types of look and feel may support this feature. For example, setDisplayedMnemonicIndex(5) decorates the character that is at position 5 (that is, the 6th character in the text). This is useful when you have two instances of the same character and wish to decorate the second instance. Sets or gets a hint as to which character in the text should be decorated to represent the mnemonic. If the labelFor property is also set (using setLabelFor), then when the user activates the mnemonic, the keyboard focus is transferred to the component specified by the labelFor property. This is helpful when a label describes a component (such as a text field) that has a keyboard alternative but cannot display it. Sets or gets the letter that should look like a keyboard alternative. Sets or gets the image displayed by the label. You can use HTML tags to format the text, as described in Using HTML in Swing Components. Sets or gets the text displayed by the label. For ease of localization, we strongly recommend using LEADING and TRAILING, rather than LEFT and RIGHT. SwingConstants interface (which JLabel implements): LEFT, CENTER, RIGHT, LEADING, or TRAILING. The horizontal alignment must be one of the following constants defined in the The int argument specifies the horizontal alignment of the label's contents within its drawing area. Setting or Getting the Label's Contents Method or ConstructorД¬reates a JLabel instance, initializing it to have the specified text/image/alignment.

For more information about X and Y alignment, see Typically, the label's painting area is exactly the size needed to paint on the label and thus label alignment is irrelevant. Label alignment simply determines where, inside the label's painting area, the label's contents are positioned. Label alignment, on the other hand, has no effect on a label's size or position. X and Y alignment are used by layout managers and can affect the way any component В— not just a label В— is sized or positioned. In the following API, do not confuse label alignment with X and Y alignment.
