These top-level Swing containers are heavyweight, that rely on the underlying windowing subsystem of the native platform. The class hierarchy of Swing's JComponent s is as follows.
JComponent and its descendants are lightweight components. For example, the figure shows three buttons: one with text label, one with an image icon, British lingerie models one with both text and icon.
The javax. ImageIcon class Java sun swing an image icon. An ImageIcon is a fixed-size picture, typically small, and mainly used for decorating GUI components. The ImageIcon class implements javax. Icon interface, and hence, often upcasted and referenced as Icon. For example. An ImageIcon uses an java. Image object to hold the image data.
You can retrieve this Image object via the ImageIcon 's getImage method. The Image object is used in the drawImage method for custom drawing which shall be discussed later. Swing's JLabel and buttons AbstractButton subclasses : support both text and icon, which can be specified in the constructor or via the setters. This example creates 3 JComponents : a JLabela JTextField and a JButtonand sets their appearances background and foreground colors, font, preferred size and opacity.
It also sets the horizontal text alignment for the JTextField. You can use the following get methods to get the dimensions of the display area of a JComponent. Each component maintains its own co-ordinates with origin top-left corner at 0, 0width and height. You can also get the origin x, y relative to its parent or the screen.
Swing supports these border types in package javax. To High country webcams in north carolina a border to a JComponentthe easier way is to choose a static method from the BorderFactory class instead of using the constructor of the Border class. The BorderFactory class provides these static methods to create borders:.
To exclude the border, you could use the method getInSets to retrieve the 4 borders in an Insets object says insetsand use insets. You can position your main application window JFrameor top-level container, on the screen, via:. You can get the screen size via static method Toolkit. You can also run your application in full-screen mode with or without decorations such as title barinstead of window-mode. Read "Swing How-To".
A quick way to center your application on Kay parker sex video clip screen is to use setLocationRelativeTo null :. Swing provides 6 text components, as shown in the above class diagram.
All text components extends from JTextComponent. Use getPassword to get the password entered in a char. JTextPane is used for formatted styled text display; whereas JTextArea is used for plain text display.
Although you can set the font and style for JTextAreaall the text is display in the same font. In JTextPaneyou can set different fonts and styles for different sections of text.
This is an excellent example that illustrates many features and concepts. A user can click a button or a menu item to trigger a specific action. Swing supports mouse-less operations, where user could use a keyboard short-cut called mnemonic to activate the action. Buttons and menu-items are inherited from AbstractButtonas shown in the class diagram. You could place a text string called button's label as well as an icon on the button.
You could use different icons for different button states: defaultIcondisabledIconpressedIconselectedIconrolloverIcondisabledSelectedIconrolloverSelectedIcon. The defaultIcon can be set Adult bladder shiness the constructor or setIcon method. The other icons can be set via setXxxIcon methods. You can set the alignment of text and button via setHorizontalAlignment and setVerticalAlignment methods.
For radio button, you can choose none or one among the group. JRadioButton s are typically added into a ButtonGroup to ensure exclusive selection. It also fires ActionEvent to its ActionListener s. Both ItemEvent and ActionEvent can be used. JComboBox can be used to provide a drop-down menu.
It supports single-selection and multiple-selection. JComboBox receives a Object array typically a String arraywhich provides the items in the drop-down list. JComboBox fires ItemEvent. JComboBox also fires ActionEvent. In this example, we have two groups of radio buttons: one group to set the horizontal alignment of the JLabeland processed via ItemEvent ; another group sets the vertical alignment and processed via ActionEvent.
The menu-bar is at the same level as the content-pane of the top-level container JFrame. To create a menu-bar, construct a JMenuBar.
A menu contains menu-item JMenuItem. This menu-bar contains 2 menus Menu-A and Menu-B. Menu-A contains 2 menu-items Up and Down. Menu-B has 1 menu-item Reset. JOptionPane provides standard pre-built diglog boxes to interact with user for both input Java sun swing output.
To create a dialog box, use one of the static methods JOptionPane. All these methods block the caller until the user's interaction is complete. Each of these methods also comes has a showInternalXxxDialog version, which uses an internal frame to hold the dialog box. Take note that input dialog returns the String entered by the user; confirm dialog returns an int JOptionPane.
Swing supports the so-called "pluggable look and feel plaf " for its JComponent s. The "look" refers to the appearance of the widgets JComponent ; while the "feel" refers to how Java sun swing widgets behave e.
You can choose to use the default Java look and feel, the native system's look and feel Windows, Linux, Macor the newer cross-platform Nimbus look and feel.
Pluggable look and feel is supported in Swing's components by separating the components into two classes: JComponent in package javax.
Nonetheless, you shall not interact with the UI delegate directly. These look and feel are supported in packages javax. There are a few ways to set the Look and Feel. You can use the static method UIManager. You can use static method UIManager.
Create a " swing. Nimbus is a polished cross-platform look and feel introduced in the JDK 1. Nimbus is highly customizable. You can use the Nimbus look and feel as is, or you can skin customize the look with your own brand. A Nimbus component can have 4 different sizes: large, regular, small and mini. You can choose the size via:. Absolute Positioning without LayoutManager shall be avoided, as it does not adjust well on screens with different resolutions; or when the window is resize.
You can provide hints on the minimum, preferred and maximum sizes of a component via setMinimumSizesetPreferredSize and setMaximumSize methods. However, some layout managers ignore these requests, especially the maximum size. You can also do these by extending a subclass and overriding the getXxxSize call-back methods.
The setSize method must be issued at the correct point, or else it will not work as Trans saharan trademap was overridden by another implicit setSize. Similarly, you can provide hints on horizontal and vertical alignments of the edges among components via setAlignmentX and setAlignmentY methods. BoxLayout honors them but other layout managers may ignore these hints.
You can also extend a subclass and override the getAlignmentX and getAlignmentY call-back methods. If you change a property of a LayoutManagersuch as hgap or vgap of GridLayoutyou need to issue a doLayout to force the LayoutManager to re-layout the components using the new Java sun swing. A container has only one LayoutManager. You need to follow with a validate to ask the container to re-layout the components.
This example creates 6 buttons, which are arranged in 3x2 and 2x3 GridLayout alternately upon clicking any Java sun swing. Alternatively, you can also change the rows and columns of GridLayout via setRows and setColumns methods, and doLayout. You can use aContainer. You can also use aContainer. You need to issue a validate call to the container after adding or removing components. This example starts with 2 buttons: one to "add" a button and one to "remove" a button.
The buttons are arranged in FlowLayout on the content-pane. For demonstration purpose, I remove all the buttons and re-add all the buttons.
Swing is a GUI widget toolkit for Java. It is part of Oracle's Java Foundation Classes (JFC) – an API for providing a graphical user interface (GUI) for Java programs. Swing was developed to provide a more sophisticated set of GUI components than the earlier Abstract Window Toolkit (AWT). This Swing Java Tutorial describes developing graphical user interfaces (GUIs) for applications and applets using Swing components. Documentation. The Java™ Tutorials Hide TOC. Using Swing Components. Using Top-Level Containers. The JComponent Class. Using Text Components The Java Tutorials have been written for JDK 8. Examples and. The Swing classes (part of the Java TM Foundation Classes (JFC) software) implement a set of components for building graphical user interfaces (GUIs) and adding rich graphics functionality and interactivity to Java applications. The Swing components are implemented entirely in the Java programming language.

The Swing group is comprised of developers involved in the design, implementation, and maintanence of Swing GUI Toolkit. This includes basic elements such as windows, buttons, scrollbars, etc. This paradigm separates an application's business logic from its user interface so that they can be evolved independently. JComponent is the core Controller class which coordinates Models and Views to display a final user component. All Swing components are inherited from JComponent. Note that components can have different views represented by different UIs. The javax.
