This Swing Java Tutorial describes developing graphical user interfaces (GUIs) interfaces (GUIs) for applications and applets, using the Swing components. Swing è un framework per Java, appartenente alle Java Foundation Classes ( JFC) e orientato La Internet Foundation Classes (IFC) era una libreria grafica per Java Grazie a questo, la maggior parte dei componenti Swing hanno associati modelli (specificati in termini di Java interfaces), il programmatore può usare.

The JButton components snap into the positions designated by the alignment interfaccr. To add a JPanel: The last thing we need to do is delete the placeholder text in the various components. Drag the resize handles of the Nickname: The small square resize handles reappear around the component’s perimeter.

The additional toolbar buttons provide convenient access to common commands, such as choosing between Selection and Connection modes, aligning components, setting component auto-resizing behavior, and previewing forms. La Internet Foundation Classes IFC era una libreria grafica per Java sviluppata originalmente dalla Netscape Communications Corporation e distribuita per la prima volta nel 16 dicembre To add title borders to the Interfaccce When the guidelines appear indicating that the JLabel is positioned in the top left corner of the JPanel with a small margin at the top and left edges, click to place the label.

In the Palette window, select the Text Field component from the Swing category. It is important to understand, however, that another integral part of component placement is anchoring. Now that the buttons are positioned where we want them, we’ll set the four buttons to be the same size for visual consistency as well as to clarify that they are related functionally.



Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)

Il sistema grafico Inteffacce risente di queste limitazioni, in quanto l’insieme dei componenti e le caratteristiche che questi ultimi offrono all’applicazione sono ristretti ad uno standard comune, un minimo insieme che possa essere supportato da tutti i sistemi operativi sui quali AWT deve funzionare.

The GUI Builder enables you to accomplish indenting easily by providing special guidelines suggesting the preferred offset for your operating system’s look and feel.

To view the project structure, use the IDE’s Files window. To resize a JTextField: Move the cursor over the form directly below the First Name: Creating a Project Because all Java development in the IDE takes place within projects, we first need to create a new ContactEditor project within which to store sources intrefacce other project files.

Guarded blocks are protected areas that are not editable in Source view. You can edit a button’s text jsva right-clicking the button and choosing Edit Text.

When the guidelines appear indicating that the JList’s top and left edges are aligned with the preferred margins along the JPanel’s left edge and the JLabel above, click to position the JList. The JButton components’ code is also added to the form’s source file which is visible in the Editor’s Source view. JLabel we added earlier.

JLabel and is chained to the JLabel. Now we’ll add the combo box that will enable users to select the format of the information that our ContactEditor application will display.


Now we’ll add the Title: The width of the buttons changes to accommodate the new names. Now that we’ve added a panel to contain our UI’s Name information, we need to repeat the process to add another directly below the first for the E-mail information. In the Palette window, select the Radio Button component from the Swing category. Add two additional JButtons below the two we already added to create a column. Before we’re finished with the JTextFields we added earlier, we need to make sure that the two JTextFields we inserted between the JLabels are set to resize correctly.

Una implementazione di default di questo opera su di un array bidimensionale. Whenever you resize the form, switch locales, or specify a different look and feel, your GUI automatically adjusts to respect the target look and feel’s insets and offsets.

Double-click the JLabel to select its display text. Move the cursor immediately to the right of the First Name: Le classi Swing sono contenuto nella gerarchia package. In the Run Project dialog select the main class name my.

Unlike the two JTextFields that we stretched to the right edge of our form, inserted components’ resizeability behavior uava automatically set.

This ensures that your GUI is automatically rendered respecting the target operating system’s look and feel at runtime.
