How do I cause a popup to get shown in Scala? I have a "backdoor" but it seems pretty ugly to me: val item = new MenuIterm(new Action("Say Hello") { def apply = println("Hello World"); }) //SO FAR SO GOOD, NOW FOR THE UGLY BIT! val popup = new javax.swing.JPopupMenu popup.add(item.peer) popup.setVisible(true) ...

Hello! I've seen a lot of examples which use getAccessibleContext().setAccessibleDescription(...) to set some "magic" description. What is the use of this description? Where can it be seen and how should it support accessibility? Why setDescription(...) is not used? Additionally, what is your opinion / experience with Java accessibil...

I want a behavior similar to e.g. Firefox where the list of available tabs does only show up if at least two tabs exist. I wasn't able to find anything like that, yet. The best idea I had was changing the layout manually: in case of one component, just add that to the surrounding panel if a component is added, remove the component fr...

But I can't find a way to customise the entire appearance of a JComboBox to achieve this. Any suggestions? Update: I don't want all JComboBoxes to look like this. I only want to create ...

I have some radio buttons whose text may be very long. Is there an easy way to word-wrap them? Yes, wrapping them in <html> tags and inserting <br> tags would work, but is there a more automatic way to accomplish this? I don't really want to roll my own typesetter. ...
I am working inside of a quite complex eclipse based application, and having a problem with a JTable based custom component inside of a JSplitPane.

I have an editable JComboBox which contains a list of single letter values. Because of that the combobox is very small. Every letter has a special meaning which sometimes isn't clear to the user in case of rarely used letters. Because of that I've created a custom ListCellRenderer which shows the meaning of each letter in the dropdown ...

Query q = em.createNamedQuery("Files.findAll"); List rl = q.getResultList(); It would probably be preferable to use the List returned by that (In this case, that would make a list of Files objects (where Files is an internal class, not java...
I'm developing a java swing application that will have several subsystems.
