I'm trying to create a custom extension of BasicSliderUI. I'm just trying to make the thumb a circle (note I'm in the Windows L&F). I've created a very simple implementation that just calls g.drawOval, but whenever I drag it, it leaves a "trail" behind. Any ideas why this is? thanks, Jeff ...
I've got a custom tree cell renderer that I'm using to render custom icons a JTree, and I really like the warning icon and the error icon that JOptionPane displays for both warning messages and error messages respectively. Obviously I can use the following code to get the icons for my own use, but this is way heavy handed and requires me...
I've implemented drag scroll before, but what's the best way to go about creating an infinite scroll pane? Of course there won't be any scrollbars and I will implement drag scroll. What I am trying to do is implement dynamic loading on an infinite surface. EDIT Of course it wouldn't actually be infinite. I am asking how to fake it. ...
I need to take text from a source as plain text and display it in a JTextPane or JEditorPane. The source text is not HTML but will contain URLs between square brackets which need to be displayed and function as hyperlinks. I've considered setting the pane's content type to text/html and surounding the url in html tags but that ends up i...
Hi everyone, I've heard about the JavaFX->AWT bridge (or hack) for a moment now. But examples I find are quite fuzzy or blur to me. So, if anyone knows an "Hello World" example for this bridge I'd be really interested ! (Just to be clear I don't need a way to embed a Swing component in a JFX animation or to launch a JFX from a Swing b...

I swear... i hope this is the last question I have to ask like this, but I'm about to go crazy.

As you know Swing/AWT gives you several ways to execute a particular action when a button is clicked. I've seen it done several different ways in the applications I've worked on. The project I'm currentl...
Hey everyone, I've been writing code in Java for awhile now, however I feel as though I lack in code "design" - that is, creating packages and separating classes and such. I'm just not sure when to create what. So, I'm practicing :) I am setting out to write a Calculator (with a Swing GUI), and I want to create a really good design for...

Is there a good example/tutorial for TreeModel and/or AbstractTreeModel that explains how to implement a custom treemodel? I'm going through a lot of head-scratching and can't seem to find some code out there which is a good starting point. edit: I did find...

In my program I frequently need to print various JComponents (generally JPanels) and I like them to be full-page. The way I do it now is by using the following code: g2d.scale(pf.getImageableWidth()/componentToPrint.getWidth(), pf.getImageableHeight()/componentToPrint.getHeight()); but this often stretches or otherwise deforms whatev...
