I'm well aware this code is horrible. I just made it so I could try out different Swing stuff. This is an interesting problem. This creates 4 buttons one for adding, subtracting, dividing and multiplying. Multiplying and adding works perfectly, no problems at all, but when the user tries to subtract it always returns 0. When the user tri...

Hi, I am new to Swing and wish to implement the download file feature in my Swing code, that would allow the user to either save or open the specific file.

I'm coming up the learning curve for Swing and am reading about InputMap and ActionMap. The O'Reilly book on Swing says the keys for ActionMap can be any Object, but by convention are Strings. Is there any reason to use an object other than a String? (e.g. an enum) I would think it's bad practice to use String literals, as they can be ...

As far as I know the Java Swing event handling is single threaded - did this change in any recent update? My problem is, that multiple event queues will tend to cause deadlocks since I've got some more locks than only...

Hi I'm working on a project for university which is essentially a re-working of the Space Invaders game with the rules changed a bit. So far I've got a main JFrame, containing a subclass of JPanel (for the background image) which contains another subclass of JPanel which I'm using for the sprites. However, when I run it the JFrame and t...

There are many methods you shouldn't call if you are not on the AWT event thread. These are generally methods that manipulate the UI in some way. Is this the case with Component's getGraphicsConfiguration(...)? It is only a getter but it appears to cause a deadlock if the event thread is waiting on the thread calling this method. Whi...
