I'm practicing MVC style programming. I have a Mastermind game in a single file, working with no problems (maybe apart of the fact that "Check" button is invisible at start). http://paste.pocoo.org/show/226726/ But when I've rewritten it to model, view, controller files - when I click on empty Pin (that should be updated, and repainted...
I've created a JPanel canvas that holds all graphics; namely JLabel. To get animated sprites to work you have to over ride the paintComponent of the extended JLabel class. I've successfully implemented animated sprites this way. Is it bad practice to have a Graphics2D canvas and then have multiple 'images' in their own Graphics2D? ...
I would like to use a JProgressBar and augment it to print its current value as well as the graphical bar. I'm guessing the best way to do this is to override paintComponent: @Override protected void paintComponent(Graphics g) { // Let component paint first super.paintComponent(g); // paint my contents next.... } but I am not...

So for example, if I write: AWTUtilities.setWindowOpacity(this, 0.5f); This will make do exactly what I want with one exception, the color is white. How can I make the color become black?

I want to make a help/instructions page for my Java program but I really don't want to have to go through and program all the frames and searching and such. Is there a package or program that I can just insert the data into and it will read it and create the dialog? I couldn't seem to find anything about it on Google. It doesn't have ...
In a master/detail view I have a series of text fields (and one or two other controls) that all pertain to the detail of the currently selected item. They all share the same DocumentListener so if you change any of them a pair of "save"/"discard" buttons become enabled. The buttons invoke a method and I can happily save/discard items. H...
Hi there, I code Java/Swing based UI. My dialogs are quite complex and there are many rules for screen dynamics: when to enable/disable buttons, when to allow to edit some fields, etc. In general there are widgets and there are some rules to set them in some state. I am wondering if there are any nice patterns, ideas how to resolve suc...
Are there guidelines for how much space controls in Swing should have around them? Also there is the question on how exactly to achieve that: Some layout managers have support for gaps between controls; some don't, where you then have to use EmptyBorder – which can be a pain as well since borders don't overlap and you may end up with too...

As I said, i have a java desktop application. The interface contains a JList and I modify the content of this list in some custom listeners that i implemented.

Hi all, I need some genius advice on this one. I have a Java Swing application that needs to launch a word processor in order to allow the user to complete some work, and then retrieve the output of that work and evaluate it later. In my head I am thinking my application can look in the normal places for Open Office or Word executables...
