The problem is quite basic. I have a JTable showing cached data from a database. If a user clicks in a cell for editing, I want to attempt a lock on that row in the database. If the lock does not succeed, I want to prevent editing. But I can't seem to find any clean way to accomplish this. Am I missing something? ...
I'm resizing a JPanel inside of a JScrollPane, and I want to make sure that the point on the JPanel where my mouse is currently located retains its position with respect to the JScrollPane after the resize (like Google maps does when you zoom in/out). I find the mouse position on the JPanel, which lets me deal with the viewport being at...

We're seeing JTable selection get cleared when we do a fireTableDataChanged() or fireTableRowsUpdated() from the TableModel. Is this expected, or are we doing something wrong? I didn't see any property on the JTable (or other related classes) about clearing/preserving selection on model updates. If this is default behavior, is there a...
What is the proper way to terminate a Swing application from the code, and what are the pitfalls? I'd tried to close my application automatically after a timer fires. But just calling dispose() on the JFrame didn't do the trick - the window vanished but the application did not terminate. However when closing the window with the close bu...

For example, so that the user could select some text in JTextArea and have it converted into speech by Services -> Speech -> Start Speaking Text. Is there a simple way to achieve that?

Here are a few references on the subject: http://www.hibernate.org/333.html http://blog.schauderhaft.de/2008/09/28/hibernate-sessions-in-two-tier-rich-client-applications/ http://in.relation.to/Bloggers...
I have a JFrame with a menu bar and a canvas covering all the remaining surface. When I click on the menu bar, the menu opens behind the Canvas and I can't see it. Has anyone experienced this? Other than resizing the Canvas (which I am reluctant to do) is there any solution? Thanks, Vlad ...
I am creating a buffered image that is going to be a snapshot of a JComponent (via paint()) and rendered inside an ImageIcon. There are a large amount of types in the BufferedImage(int width, int height, int imageType) constructor, but which one should I use? I am sure that any of them would work, but which ones are better than the o...
In my database application I sometimes have to deal with null strings in the database. In most cases this is fine, but when it comes do displaying data in a form the Swing components - using JTextField for example - cannot handle null strings. (.setText(null) fails) (EDIT: I just noticed that JTextField actually accepts a null string, b...
Hi, since JTree & TreeModel don't provide tooltips straight out-of-the-box, what do you think, what would be the best way to have item-specific tooltips for JTree? Edit: (Answering my own question afterwards.) @Zarkonnen: Thanks for the getTooltipText idea. I found out another (maybe still a bit nicer) way with overriding DefaultTr...
