Which Swing layout manager to get my desired layout?

阅读更多关于 Which Swing layout manager to get my desired layout?

问题 I am trying to make a basic login menu following this mock up : I decided to put this whole menu into a JPanel so I can switch to another panel once the connexion is successful. So I decided to use a Borderlayout to have the title in north area and the connect button in the south area . I made the center of the borderlayout a panel itself .

阅读更多关于 How do I keep JTextFields in a Java Swing BoxLayout from expanding?

I have a JPanel that looks something like this: JPanel panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS)); ... panel.add(jTextField1); panel.add(Box.createVerticalStrut(10)); panel.add(jButton1); panel.add(Box.createVerticalStrut(30)); panel.add(jTextField2); panel.add(Box.createVerticalStrut(10)); panel.add(jButton2); ... //etc. My problem is that the JTextField s become huge vertically. I want them to only be high enough for a single line, since that is all that the user can type in them. The buttons are fine (they don't expand vertically). Is there any way to keep

How to overlay, resize and centre a component on a JPanel?

阅读更多关于 How to overlay, resize and centre a component on a JPanel?

问题 I've spent a while reading and experimenting here, and come up with a few approaches, but not got any of them to work completely yet, so I would like to know what more experienced Swing programmers would do. The main window of my application contains a custom subtype of JPanel, which is used to display an image calculated from a mathematical function. This can take some time to calculate, so while this happens I display a text message and a progress bar superimposed on the middle of the panel

more efficient layout than Box

阅读更多关于 more efficient layout than Box

I've got some very old code which uses a Box to list some information. I create it like so: Box patterns = Box.createVerticalBox(); Very (very) often, new items are added and old items are removed eg: label = new JLabel("xyz"); patterns.add(label); and later patterns.remove(label); whenever something is added ore removed I have to have it repaint, so I call: patterns.revalidate(); patterns.repaint(); Problem is, since this happens very often it chokes up the UI. I think I need a better implementation in order to make it more efficient. I know I could maintain a list of the active items in the
