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.

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
