Basics of Java Netbeans

Shrey Goswami

In this presentation you will learn how to use coponents offer by Swing API in Java Netbeans.

You will also be introduced by some basic things like Pallete, Design Area, the Property Editor, and the Inspector which are very useful to know.

Introduction

Netbeans IDE: layout.

The Pallete

How Pallete Looks in Netbeans?

Pallete contains all components which you can use while making a GUI application. The Pallete provides you components like jTextField,jLabel etc.

You can design Swing GUIs by dragging GUI components from a palette onto a canvas. 

The Pallete

The Design Area

The Design Area: Design View

The Design area is where you can drag the components from Pallete and design the GUI application.

In Netbeans you are provided with an option to toggle between source and Design by clicking in button provided.

For Ex- In this I have designed a GUI using swing components in jFrame object .

The Design Area: Source View

Take a quick look at Source View where you can add the code for components.

Property Editor

Property EditorThe Property Edior edits the property of Swing Components.

You can edit properties very easily using this property editor. You can see it in the screenshot provided.

jLabel – it is a label used to display a single line text in application. jTextField- It is used to take a input from user in a application. jTextArea – It is used to display multi line text, it also supports line

wrap. We can make it editable or non editable by changing property. jCheckbox-A checkbox is a labeled toggle switch. Each time the user

clicks it, its state toggles between checked and unchecked. Swing implements the checkbox as a special kind of button.

JRadioButton-Radio buttons are similar to checkboxes, but they are usually arranged in groups. Click on one radio button in the group, and the others automatically turn off. They are named for the preset buttons on old car radios.

jList- It is a list of items from which selections can be made. Multiple elements can also be selected at a time.

jComboBox- It provides a dropdown list of items. New Items can be added to it.

Useful Swing Components.
