The JFC changed in 1.5, .useful needs a tweek

Thu, 17 May 2007 09:46:08 GMT

Bee-u-t-ful code I must first comment. Wow. I was trying to use the AutomatedXMLTree.java. I note the date of posting this code is 2004. Evidentially, XML is a moving target and moving fast. Using the XMLTree code in my choice of JDK 1.5 or 1.6, I get ---> [#document: null]. Because of all the different tools required, the choice of parser, the methodology, the JFC's latest changes, the w3org rewriting the xml specs, ad infintim, it strikes me there is a light year's worth of difference between code that ran in 1.42 and code that runs in 1.5. I searched the Sun forums and I find this insight: /* The parse() method doesn't return null, * "[#document: null]" is what's returned by toString() * method when you print it. * Call getDocumentElement() method for * the document returned by parse() to get * the root node of the document. */ Because .toString() is a method of everything JFC (for instance, any System.out.println() ) it is difficult for me to discover where in the .useful API I should be making modifications.

RE: how to implement resizing of tree node (or any Box) by dragging its edge?

Hey Anil, Got your email with a program. That's a pretty uncommon task you have. I think you will need to accomplish it by yourself! If you want you can make your contribution to dotuseful then. A small hint: you might look at how Swing resizable containers work. Good luck! Denis Krukovsky. - 1 reply

Yes, if the user drags the border - just as in a JFrame. Dont misunderstand me but it will be good if you can implement this functionality for dotuseful, otherwise dotuseful will be not useful. We are looking for dotuseful to provide us with functionality that can be useful to us - without all of us reimplementing the wheel. thanks, Anil - 2 replies

Not so, each node has two JTextAreas where one can type into. so we do need to enlarge and shrink each node. Do you know how? thanks, Anil - 2 replies

Hi Anil, The new dotuseful forum is here. Quick answer is that I think you would not to resize a tree node by dragging it. What you can think about is to resize a container you have your JTree in. You can try putting your JTree into JSPlitPane for example. Denis Krukovsky. - 1 reply

how to implement resizing of tree node (or any Box) by dragging its edge?

Mon, 20 Mar 2006 16:58:46 GMT

Hello I notice there are 2 forums for dot useful? Which one to use? ---------- Hello, Suggestion: implement resizing of tree node (or any Box) by dragging its edge. Each node of my JTree contains JPanels in a Box. But actually, this is a general question. Is there a 'best' way to implement resize of a container by dragging its edge? This might be a good enhancement to dot-useful. I dont know how the details of how to implement this. Do you know exactly how? Please email if you have a solution. thanks, Anil - 3 replies
