Before going further, we need to edit the display text of interfavce JLabel we graviche added.
Getting Started with Swing. To add multiple JLabels to the form: JLabels on the second row such that the JTextField overlaps both and is aligned to their baselines.
Afterwards, we’ll set the four buttons to be the same size so they can be easily recognized as offering related functionality.

Once placed, new components are also anchored to the nearest container edge or component to ensure that component relationships are maintained grafche runtime.

To view the project structure, use the IDE’s Files window. This speeds the GUI design process, enabling you to quickly create professional-looking visual interfaces that work.
It makes these suggestions based on the positions of the components that have already been placed in the form, while allowing the padding to remain flexible such that different target look and feels render properly at runtime.

Beginning of Tutorial Next page: The GUI Builder provides helpful inline hints and other visual feedback regarding where components should be placed on your form, automatically snapping components into position along guidelines. Notice that the suggested vertical spacing between the two JPanels is much narrower than that at the edges.
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 and other project files. Notice once again the baseline alignment guidelines that appear to assist us with the positioning.
Now we need to add the buttons that will enable users to confirm the information they enter for an individual contact and add it to the contact list or cancel, leaving the database unchanged. This will, in turn, ensure that our ContactEditor application’s contact information will be displayed in the mail format of our choosing.
