Hi, I need to develop some java gui using swing. A few years ago I did develop a bit with swing. But it was pretty exhausting, you see, back than there weren't much tools to help you. But I do believe today it should be easier, there must be tools. I would like to use some kind of a generator or maybe a utility or even a framework. I kn...
Hi SOers, I need to change the direction of the growth of JTextField object when more characters are added to it. Currently when I add more stuff to it, it grows from left to right but I need this growth of the bounds of the JTextField from right to left. For e.g. when I add "StackOverflow" to this JTextField the o/p is, <empty space>St...
i had a situation where i had to use this setDataVector function. I was puzzled to see there was an extra second argument(Vector columnIdentifiers) in the function. I'm just resetting the data. Why do i need to send the column identifiers?? And it doesn't take the old column identifiers by default if i don't pass the second argument. Irr...

I have created a custom JPanel that displays images (lets call it MyPanel), I have added this to JFrame's contentPane. I want JFrame to be resized automatically to fit the MyPanel when image changes. It looks like I need to call frame.pack() to do this. Calling pack() from MyPanel increases coupling so I don't want to do that. To solv...

Hi Everyone, I have an application which opens multiple JIFs, But I only want to create a single instance of the JIF, so I use these function to check that, and I use dispose to close the JIF after a key is pressed(JDesktopPane.getSelectedFrame().dispose()). However after 2-3 successive disposes, it doesn't create a new JIF? Am I doing ...
So the problem that I am having appears to be a bug that occurs only on Linux. I'm trying to have my swing app record when a key is pressed down, then to detect when that key is released. Now that shouldn't be in issue because KeyListener is supposed to handle this for me. The problem is that when I hold the key down I get lots of repea...
I would like to add a hint value to my JTextField. It should look like Firefox rendering of <input type="text" title="bla">. This creates a edit field with the text 'bla' in the background. If the textbox has focus the title-text disappeares and just reappears if the user leaves the editbox without text. Is there a (free) swing componen...

As is widely known, anything related to Swing components must be done on the event dispatch thread. This also applies to the models behind the components, such as TableModel. Easy enough in elementary cases, but things become pretty complicated if the model is a "live view" of something that must run on a separate thread because it's cha...
