    Default User Interface Problems

    Hi,
    I am trying to create a specific user interface according to certain specifications given to me... I have figured out how to put the panels together and I have everything almost where I want it.

    I am having a lot of trouble figuring out how to make my schedule button a more reasonable size and also with bringing the JTextFields closer to their corresponding labels. If you compile this you will see how the two JTextFields are way too far away from their labels and the schedule button is way bigger than needed. Also the time JLabel is off to the left too far, I would like it more centered in the leftPanel. Any help would be much appreciated. thanks.

     
            private JTextField startAddress = new JTextField(10);
    	private JTextField endAddress = new JTextField(10);
    	private JList hourDisplay = new JList();
     
    	private JList minDisplay = new JList();	
    	private JScrollPane minPane = new JScrollPane(minDisplay);
     
     
    	private JTextArea itinDisplay = new JTextArea(22,50);
    	private JScrollPane itinPane = new JScrollPane(itinDisplay);

    	final static int maxGap = 20;
    	private double hour = 00;
    	private double min = 00;

    Why don't you use IDE instead of notepad?

    If you haven't yet, browse the following webpage: A Visual Guide to Layout Managers (The Java™ Tutorials > Creating a GUI With JFC/Swing > Laying Out Components Within a Container)
    Layouts can be mixed and matched, and calling setPreferredSize will help with the sizing

    Where did the OP say s/he was using notepad? And besides, I actually recommend that newbies stick with a basic editor for as long as possible. Relying on an IDE, especially code generators, actually makes it harder to learn.

    thanks for the replies, unfortunately I'm still not getting it.... When i use setPreferredSize it's not working properly the button's width refuses to change.

    From his/her code, it seems like he uses notepad. Anyways, our concern is not what he/she uses, but what's his problem.

    How so?

    I can mostly agree with this, other than when people post IDE-generated code without understanding it. But you were the one that started the discussion on using an IDE instead of notepad. I just threw in my dissenting opinion in the conversation that you started.
