I'm pretty sure I've done it this way before, but for some reason, the JFrame won't show up when I run it. JLabel originalString = new JLabel("Original String: " + str.getMutator()); JLabel currentString = new JLabel("Current String: " + str.getMuta...
Is there a way to run a swing component through a pyqt widget? I'd like to write a small project using pyqt, but there's a java library that draws to a JPanel-inherited panel, and it would be really convenient to be able to embed one into the other. I know I could use jython and qtjambi, but I was curious if there was an alternative su...

Everytime the use clicks on a row of this list, the selected_row value should be updated and the string "The format row selected is ...." should therefore change. However after c...
We have an old Java Swing application. we need to display thousands, hundreds of thousands small circle spots on the canvas based on the real data. Right now we have an image file of a small circle spot. When we need it, we draw that image onto the canvas, thousands, hundreds of thousands times. Now I am think it may be better (better p...
My wizard isn't rendering correctly in Eclipse 3.6.1. It's leading me to wonder: when does one have to use Composite.pack()? Some SWT examples have it, and some don't. How my wizard pages renders depends on the target platform. If I run my plugins in 3.5.2, they render correctly as soon as I open them. But in 3.6.1, their contents areas...
Is there any naming convention for swing components such JButtons..? or does any body knows any good way for doing that? Thanks ...
I haven't understood this since I had started working with Swing. Why BoxLayout with Y-Axis sorting places (from the example) buttons one under another with space all the way to the end of panel (that's what I thought how it works) but placing JPanels same way but making them stretch. Would someone be so kind to explain to me the phenome...
Hi, I'd like to create an app where some events are supposed to be handled as if they were delivered to parent containers. For example I've got a JPanel which contains JLabel. The top JPanel implements mousepress and dragging right now. What do I need to do, in order to make the events look like they arrived to JPanel instead of the labe...

I want it to simply draw a line that goes from P1(0,1) to P2(1,2) inside my graph. here is my code : import java.awt.*; import javax.swing.*...
EDIT: As in the example (now written by me) what I'm trying to achieve is packing JLabel (+JTextFields, not in the example) into JPanel with FlowLayout and sorting these panels with BoxLayout one under another but limitting it with JScrollPane so I can specify how high the view area is and if those JPanels (packed JLabels) exceed the hei...
There should be an error/omission in the next code but I can't see where mostly because I've never used threads. Can someone please find what I'm missing? import java.awt.BorderLayout; import java.awt.Button; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.util.Timer; import java.util.TimerTask; imp...
I believe an application exists that lets you visually analyze your swing application, I've used it before but I can't remember the name. From what I remember, you launch your app from within this analyzer and you can hover over any component and the analyzer will tell you the properties of the component, such as the type, name of the h...
I want to show the dialogs JColorChooser and JFileChooser programmatically from a method called when I submit a buttons. After the button is clicked the method is invoked but the dialogs won't display. I have a JFrame with a null layout (absolute positioning) and, e.g., the following code: public class _TEST_ extends JFrame { priv...
Apologies if I'm missing something silly... but I'm experimenting with NetBean's WYSIWYG Swing GUI builder, and am having some issues with GridBagLayout. When writing a Swing application from scratch, I'll typically establish the column and row weights in one fell swoop at the time I first declare the layout. Something like this: fina...

I have an application that uses Swing. The display I am working on, uses a Box with a Horizontal Layout as the top container. In it, are three other boxes (which actually contain the content). The appearance to the user is a window with three panes, arranged horizontally across the screen. What I want to do is give the user the ...
