Action behind plus/minus icon tree2 tomahawk
Hi,
does anyone know if there is a possibility to put an action
behind the plus/minus (expand/collapse) icon in a tomahawk tree2?
What I want is to execute a method which adds some more children to the
tree
by clicking the plus icon....
Thanks a lot!
Wolfgang

You can use the jsf AA tree code as an example:

#{node.leaf} will return a boolean. If it returns true the component in question will be rendered, else... not.
Even if you're using your own TreeNode (as I'm sure most of us are), isLeaf is in the TreeNode interface so your TreeNode must have this method. If the node is meant to be expandable then it should return true.

Hi,

t:graphicImage component and
I set rendered to true..... strange...
But could you please explane to me what this " rendered=#{!node.leaf} "
is actually working???

Re: Action behind plus/minus icon tree2 tomahawk
Posted by Wolfgang <wk...@ebi.ac.uk>.
Hi,
thanks for this greate page! I guess it is really a good solution, but
it does not work ;)
The first problem I have is that the plus and minus icon ist not shown
because of the
rendered="#{!node.leaf}". If is set this to true the minus icon appears,
but it is not clickable.
Furthermore I had to change the processToggle method a bit because I do
not use the standard
TreeNodeBase node. I guess this should work, but I can't test it because
there's no icon to click.
I do not really understand how that rendered stuff is working and I
can't find something with "leaf"
in the java code.
So maybe you can have a quick look at the code:
http://nopaste.php-quake.net/14631
It is actually exactly the same as in the example...
Heres my bean: http://nopaste.php-quake.net/14633
Thanks in advance!

I followed that same example. Basically you need to disable the +/- generated by tomahawk and use your own. Which is what Bill does in his example. In your command link, or ajax link use t.toggleExpanded for the action and then have an actionListener call toggle(ActionEvent e) to load the children.

Hallo!
I think you can do so using ajax4jsf.
There is an example here:
http://www.jroller.com/plainoldweblog/entry/use_tomahawk_tree2_and_ajax4jsf
I used this and it worked fine.
When toggling the Items the method public void processToggle(ActionEvent
p_event) is called and there is the possibility to dynamically build the
tree data.
(In the example the functions loadChildren(node); and unloadChildren(node);)
