[Jtreemap-user] JTreeMap still active?

[Barrie T. <bae...@gm...>]

I've stumbled across this project looking for a TreeMap implementation in SWT.

I'll re-ask Scott's question: Is JTreeMap still active?

>From the home page "We believe that JTreemap is the only java,
open-source and maintained library for treemapping. JTreeMap
components are released under the business-friendly Apache 2.0
license.", so unless the project is miraculously bug free, the last
release was in 2007, this is probably no longer an accurate statement?

[Jtreemap-user] JTreeMap still active?

[Scott M. <mor...@gm...>]

Is this project still active?  I have a few enhancements (performance
and functional) that I'd like to make and I'm considering forking it
into a new project on google code.  But if the project committers are
still around I'll go through the patch process.

thanks
scott

Re: [Jtreemap-user] on click event hooks on leaf nodes

[David P. <Dav...@be...>]

Hi,

 

After inspecting the source for the various components I found one
fairly inefficient solution that requires iterating through all leaves:

 

Add a MouseListener to the JTreeMap object:

 

jTreeMap.addMouseListener(new ClickListener(this));

 

Inside ClickListener() in the mousePressed call:

 

TreeMapNode node =
map.curTree.getActiveLeaf().getActiveLeaf(arg0.getX(), arg0.getY());

 

Gives me the leaf in question, which I can then extract whatever info I
need from. The getActiveLeaf call is where the iteration happens. It's
effectively searching for which leaf is at the x,y specified.

 

 

David

Subject: [Jtreemap-user] on click event hooks on leaf nodes

 

Hi All,

 

I was bored on Friday and decided to attach a jtreeview program to the
live market data feed from betfair.com to show relative market activity.
What I'd now like to be able to do is hook into the click events for the
leaf nodes so I can add some custom behaviour. I had a poke around in
the docs but couldn't find anything. Thanks for the great work so far on
the lib!

 

Cheers,

David Prime
