Adjusting the CelsiusConverter GUI
First, double-click the
JButton to change the default text that was inserted by the IDE. When you erase the text from the
JTextField , it will shrink in size as shown below. Change the text of the
JButton from "JButton1" to "Convert." Also change the top
JLabel text to "Celsius" and the bottom to "Fahrenheit."
Setting the Component Text
Next, shift-click the
JButton components. This will highlight each showing that they are selected. Right-click (control-click for mac users) Same Size -> Same Width. The components will now be the same width, as shown below. When you perform this step, make sure that
JFrame itself is not also selected. If it is, the Same Size menu will not be active.
Setting the JTextField and JButton Sizes
Finally, grab the lower right-hand corner of the
JFrame and adjust its size to eliminate any extra whitespace. Note that if you eliminate all of the extra space (as shown below) the title (which only appears at runtime) may not show completely. The end-user is free to resize the application as desired, but you may want to leave some extra space on the right side to make sure that everything fits correctly. Experiment, and use the screenshot of the finished GUI as a guide.
The Completed GUI
The GUI portion of this application is now complete! If the NetBeans IDE has done its job, you should feel that creating this GUI was a simple, if not trivial, task. But take a minute to click on the source tab; you might be surprised at the amount of code that has been generated.
This figure has been reduced to fit on the page.

To see the code in its entirety, scroll up and down within the IDE as necessary. You can expand or collapse certain blocks of code (such as method bodies) by clicking the + or - symbol on the left-hand side of the source editor.
