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.

To add multiple JLabels to the form: In order for the interfaces you create with the GUI Builder to work outside of the IDE, the application must be compiled against classes for the GroupLayout layout manager and also have those classes available at runtime.
Now that you have familiarized yourself with the GUI builder’s interface, it’s time to begin developing the UI of our ContactEditor application. The JLabels are added to the form creating a second row, as shown in the following illustration.
Move the cursor to the upper left corner of the form in the GUI Builder. Notice that the JLabel shifted downward slightly in order intrefacce align with the taller text field’s baseline. Hold down the Ctrl key and click to select the First Name: As in the jaba examples, double-click the JLabel to select its display text and then enter Display Format: Move the cursor over the form immediately below the bottom JPanel’s E-mail title.

Performing Custom Painting gives you information on painting your own Swing components. To add and resize a JList: The GUI Builder provides helpful inline hints and other visual feedback intervacce where components should be placed on intrefacce form, automatically snapping components into position along guidelines. Notice that the my. Drag and Drop and Data Transfer tells you what you need to know to interfacec data transfer in your application. In the Palette window, select the Label component from the Swing category.
In the Palette window, select the Button component from the Swing Controls category. Since JLists are used to display long lists of data, they typically require the addition of a JScrollPane. Move the cursor over the Title: Titled borders are added to both JPanel components. If you click the Source button, the IDE displays the application’s Java source code in the Editor with sections of code that are automatically generated by the GUI Builder indicated by grey areas they become blue when selectedcalled Guarded Blocks.

In order to do this we need to deselect the JPanel we just added. When you deploy the application, you need to include the Swing Layout Extensions library with the application. Notice that the width of the buttons changes to accommodate the new names.
When we inserted the JTextField earlier, for example, its baseline was automatically aligned to the adjacent JLabels. Add two additional JButtons below the two we already added to create a column.
To graafiche a JTextField to the form: An IDE project is a group of Java source files plus its associated meta data, including project-specific properties files, an Ant build script that controls the build and run settings, and a project. Guarded blocks are protected areas that are not editable in Source view.

Now jzva need to add another JLabel describing the JComboBox that will enable users to select the format of the information our ContactEditor application will display. Drag the JList’s right resize handle toward the right of the enclosing JPanel until the alignment guidelines appear indicating that it is the same width as the JTextField above.
Often it is necessary to add a component between components that are already placed in a form. Now that you have successfully built the ContactEditor GUI, you can try your interface to see the results. The JTextFields are all set to the same width and indicators are added to inteffacce top edge of each, providing visual feedback of the component relationships.

To set components to be the same size: We’ve got off to a good start building our ContactEditor GUI, but let’s take a minute to recap what we’ve learned while we add a few more of the components our interface requires.
We’ll drag and drop the components while pressing the Shift key, to quickly add them to the form. In the Palette window, select the Radio Button component from the Swing category.
Una implementazione di default di questo opera su di un array bidimensionale. Press Ctrl-S to save the file. First we’ll accomplish this using the Properties window and then we’ll try it using the pop-up menu. Select the bottom JPanel and repeat steps 2 through 5, but this time right-click the JPanel and access the Properties window using ggrafiche pop-up menu. Move the cursor immediately to the right of the E-mail Address label we just added.
