![]() The following figure shows the Property Editor for the newly added JFrame object: The Property Editor is intuitive to use in it you will see a series of rows - one row per property - that you can click and edit without entering the source code directly. The Property Editor does what its name implies: it allows you to edit the properties of each component. Laying Out Components Within a Container. For more information about these components, see: It also tells the application to "exit on close", performs some layout-specific tasks, then packs the (soon to be added) components together on screen.ĭon't feel that you need to understand this code in any detail we mention it here simply to explore the source tab. Commonly expected behavior (such as quitting when the user clicks the "close" button) is auto-generated by the IDE and appears in the source view between uneditable blue sections of code known as guarded blocks.Ī quick look at the source view reveals that the IDE has created a private method named initComponents, which initializes the various components of the GUI. The figure above shows a single JFrame object, as represented by the large shaded rectangle with blue border. You can toggle between views at any time by clicking their respective tabs.

This figure has been reduced to fit on the page.Ĭlick the image to view it at its natural size.įrom this list, our application will use only JLabel (a basic text label), JTextField (for the user to enter the temperature), and JButton (to convert the temperature from Celsius to Fahrenheit.) You can probably already guess what many of these components are for, even if this is your first time using them ( JLabel is a text label, JList is a drop-down list, etc.) The Palette contains all of the components offered by the Swing API. In fact, the only features that you really need to understand are the Palette, the Design Area, the Property Editor, and the Inspector. Taking it 'proprietary', going for the 'roach motel' model of non-standard standards - 'customers check in, but they don't check out.It is not necessary to learn every feature of the NetBeans IDE before exploring its GUI creation capabilities. Java creator James Gosling has said, "It's not so much that Oracle is backing off on EE, but that it's backing off on cooperating with the community. ![]() The much delayed core Java Enterprise Edition (JEE) 8 may finally launch in 2017. Now, OpenOffice is on its deathbed.Īnother significant issue is that Oracle no longer makes Java a priority. The most relevant of Oracle's past moves away from Sun's software to the NetBeans situation is how Sun abandoned OpenOffice. ![]() In 2013, Oracle sunsetted most of Sun's virtualization technologies. Larry Ellison, Sun's ruler no matter his title, dropped OpenSolaris immediately. Since then, Oracle has been shedding Sun's software programs. Oracle picked up NetBeans as part of its 2010 deal for Sun. NetBeans has a long history dating back to 1995. Heading back to school? These are the best deals for students to save on tech
