To add icons to a button, specify a default button, or use HTML in a button involves one or more of these steps: 1 To specify the default icon (which is shown when the button is enabled), pass the icon to the JButton constructor You can also set the default icon by calling setIcon( ) 2 To specify an icon that is displayed when the button is rolled over by the mouse, call setRolloverIcon( ) 3 To specify an icon that is displayed when the button is disabled, call setDisabledIcon( ) 4 To specify an icon that is displayed when the button is pressed, call setPressedIcon( ) 5 To specify a mnemonic for a button, call setMnemonic( ) 6 To define a default button (a button that will be pressed when the user presses ENTER), call setDefaultButton( ) 7 To display HTML inside a button, begin the string with <html>

To create a push button that contains an icon, you will use this JButton constructor: JButton(Icon icon) Here, icon specifies the icon used for the button To create a push button that contains both an icon and text, use this constructor: JButton(String str, Icon icon) When both text and an icon are present, the icon is on the leading edge and the text is on the trailing edge However, you can change the relative positions of image and text The icon specified in these constructors is the default icon This is the icon that will be used for all purposes if no other icons are specified

The default icon can also be specified or changed after it has been created by calling setIcon( ) It is shown here: void setIcon(Icon defIcon) The default icon is specified by defIcon JButton also allows you to specify icons that are displayed when the button is disabled, when it is pressed, and when it is rolled over by the mouse To set these icons, you will use the following methods: void setDisabledIcon(Icon disabledIcon) void setPressedIcon(Icon pressedIcon) void setRolloverIcon(Icon rolloverIcon) Once the specified icon has been set, it will be displayed whenever one of the events occurs Keep in mind, however, that the rollover icon may not be supported by all look and feels You can determine if the rollover icon is enabled by calling isRolloverEnabled( ) Setting the rollover icon automatically enables the rollover icon You can explicitly set the rollover-enabled property by calling setRolloverEnabled(true) You can define a button that will automatically be pressed when the user presses ENTER on the keyboard This is called a default button To create a default button, call setDefaultButton( ) on the JRootPane object that holds the button This method is shown here: void setDefaultButton(JButton button) Here, button is the push button that will be selected as the default button Remember, this method is defined by JRootPane and, therefore, must be called on the root pane You can obtain a reference to the root pane by calling getRootPane( ) on the top-level container You can add a mnemonic to the text displayed within a button by calling setMnemonic( ) When this key is pressed in conjunction with the ALT key, the button will be pressed This method is shown here: void setMnemonic(int mnemKey) Here, mnemKey specifies the mnemonic It should be one of the constants defined in javaawteventKeyEvent, such as VK_A, VK_X, or VK_S The KeyEvent class defines VK_ constants for all the keys on the keyboard Therefore, assuming a JButton called jbtn, you can set the keyboard mnemonic to T with this statement:
jtbnsetMnemonic(KeyEventVK_T);
