Hi, Quick background, I am using Netbeans to develop this (I don't have much experience with Swing and have lost points on experience at the chance to gain development speed). In Netbeans it is obviously restrictive as to what code you can modify to stop novice users breaking the code (which I have already amusingly done once) Anyway, I...
I have an application that starts out as an Eclipse RCP application and then fires up a JFace ApplicationWindow, complete with a simple menu, toolbar, display widgets, etc. This second application window includes some model dialogs (extended from JFace Dialog and TitleAreaDialog) from the action classes.

This is basically a architectural question. I want to implement composite pattern in handling Swing components; that is, I want to combine several components with their listeners and logic behind a single component for easier handling. Consider for example a simple directory browser; say, a JTree in JScrollPane with some logic which ha...
I'll try to explain my problem as simply as possible but it's a tricky topic and people who haven't encountered the issue probably won't know what I'm talking about. I want to use a BorderLayout using west, east, north, south, etc. components that are my "normal" components (JLabels, JButtons, etc.) then I want the center component to b...
I've read the definite tutorial on key bindings a few times, but my brain cache doesn't seem large enough to hold the complicated processes. I was debugging a key binding problem (turned out I was using the wrong JComponent.WHEN_* condition), and I stumbled upon a concise and hilarious javadoc for the package private javax.swing.Keyboar...

Hi, I am trying to use a JSplitPane in Netbeans 6.9.1, but I can not configure it properly for some reason. E.g. I add a jtree and a jtable in a jframe. Then I use "enclose in splitpane". Then I set the orientation to vertical (from horizontal). Problem, when I try to adjust the divider location, I can not place it where I want. Either ...

I'm having a little trouble building the grids for a Battleship game for my Java class. So far, I can easily make a for loop to add JPanel or JButton objects to the JFrame. However, my issue is that I'll need to use those Panels or Buttons again when playing the game (such as clicking on a button to see if your opponent put a ship on tha...
Hi all, I'm currently trying to implement a Swing/GUI that could be regarded as a RDF editor. For each property , I can add/remove one ore more widgets storing the values (JTextField, JScrollPane+JTextArea, JCombo, etc.... ). I've been trying to use the GridBagLayout to put the Components in place but I can get any good result. Any ...

How to make the update immediately when the jSpinner value was changed. ChangeListener listener = new ChangeListener() { public void stateChanged(ChangeEvent e) { jLabel.setText(e.getSource()); } }; spinner1.addChangeListener(listener); The code above doesnt change the label text automatically, it required you to click again ...
I have been trying to find a way (in Swing) to connect two JInternalFrames with a CubicCurve2D (otherwise known as a cubic bezier curve). The overall effect I'm trying to achive is an interface similar to Yahoo! Pipes (the curve should go from the bottom of one internal frame to the top of the other). Has anybody here done this before? ...
Okay, I want to override JTextArea's Document's remove method, I can't figure out what class to extend. I can't extend Document cause it's a interface, and that also means it must not be the document that JTextArea creates. So how exactly can I easily override my JTextArea's document's remove method? ...
My problem is, that I have simple Pojos or simply objects that contain data. These can vary and new types of these can be added during runtime. So I need a Swing GUI to input text to them. Is there a framework that dynamically creates a Swing GUI from a POJO during runtime? Technically, it should be possible using reflection and/or ann...
