New objects can be added to the ArrayList elsewhere in the GUI, so I need to know when it is updated, so I can refresh the dropdown menu. From what I can gather, my two options are to extend the ArrayList class to allow me to add my own change...

I've been running up against a problem with Java Swing + my Wacom Graphire tablet for a few years in several Java applications and have now encountered it in my own. I use a pen tablet to get around wrist issues while clicking a mouse, and it works fine under Windows except when I'm using Java applications. In Java applications, the sin...

I have the f...

I'm messing about with HTMLDocument in a JTextPane in Swing. If I have this situation: <html>... <p id='paragraph1'><span>something</span></p> <span id='span1'><span>something else</span></span> ...</html> (the extra <span> tags are to prevent Swing from complaining that I can't change the innerHTML of a leaf) or this situ...

How do I easily edit the style of the selected text in a JTextPane? There doesn't seem to be many resources on this. Even if you can direct me to a good resource on this, I'd greatly appreciate it.
