Hello! How could I make non-rectangular windows with soft borders in Java? Soft borders (also known as soft clipping) are borders without aliasing artifacts. I searched the web a lot and found several posts about translucent and/or non-rectangular windows. The topic "soft border" is confusing. It seems that the information I found dea...

Hi, I have a question about GUI design, specifically with Java Swing and creating clean separation between presentation and model. It's a bit difficult to describe, but essentially we have lots of reference data in our system (i.e. that would correspond to lookup tables in the DB). We want people to be able to edit them all from one scr...
I've figured out how to get a JTable to be sorted properly, but I can't figure out how to get it to automatically update the sort order when a table cell is changed. Right now, I have this (admittedly long) code, mostly based on that in the Java Tutorial's How to Use Tables. I've highlighted the changes I've made with // ADDED. In this ...

On the iPhone scrolling through lists is animated smoothly. Ignoring the inertia effect (though having it would be cool as well) - how would I go about making a Swing listbox scroll smoothly like that?

I have some Java user interface controls that I want to host in my .NET application as I can't afford to rewrite them. How can I do that? Do I need to wrap them up in COM? How do I do that? I want the component to sit on a form with other components written in .NET. ...

I remember having once seen a list of properties that could be set on Swing components to make them look more native on Mac OS X. This included ways to mark "dirty" documents with the "dot" in the window close button, open dialogs as sheets (not sure about that, but sure would be nice) etc. I know Apple has let Java down as a "primary"...

Currently, I add a pound sterling () sign to the Java source and compile the resulting Swing component shows as the square (unsupported character) symbol.

Hi, i am using a ThreadPoolExecutor with a thread pool size of one to sequentially execute swing workers. I got a special case where an event arrives that creates a swing worker that does some client-server communication and after that updates the ui (in the done() method). This works fine when the user fires (clicks on an item) some ev...
