Seaside.WATree expand and element position

Hi,

I work with VW 7.4 and i'am new to seaside.

I'm interested to work with WATree but i found two problem.

A) First problem : WATree expanded

    is possibol to work with WATree not expanded all on the page, but in a "treeView list " with horizontal and vertical scroll bar ?

  By Lukas  suggestion i think to resolved it with :

        "html div
       style: 'height: 200px; overflow: scroll' ;

with: tree "

For test it i'have change WAExampleBrowser renderContentOn: method to:

renderContentOn: html
html
  cssId: 'test-forms';
  table:
    [html tableRowWith:
      [html form:
        [html
         selectFromList: self allClasses
         selected: class
         callback: [:c | self class: c].
        html submitButtonWithText: 'OK']]
     with:
      [html form:
        [html
         selectFromList: self allSelectors
         selected: selector
         callback: [:s | self selector: s].
        html submitButtonWithText: 'OK']]].
html horizontalRule.

(component isKindOf: WATree)
  ifTrue:
   [html div
    style: 'height: 200px; width: 200px; overflow: scroll';
    with: ( component renderTreeOn: html )]
  ifFalse: [html render: component].

hasAnswer
  ifTrue:
   [html horizontalRule.
   html
    bold: 'Answer ';
    text: answer printString]

Now then i work with WATree the div work fine;

but under it there is another WATree used by WATree selectBlock: [ :class | component call: (WABrowser fullOnClass: class) ];

What do i do to remove it from interface ?

( with new reference for call : WATree selectBlock: [ :class | myComponent call: (WABrowser fullOnClass: class) ];

+Object

+Object

B) Second problem : tree position

Now then rendering one WATree it start always to root of the tree ;

            or to one specific node with lose of upper hierrarchy.

    My question is :
        is possibol display the WATree positioned on one specific node with upper and under hierarchy ?

or render WATree to the last position node select with upper an under hierarchy ?

Thanks & Regards,

Dario Trussardi Romano

Remove "renderTreeOn: html", you should never all render methods of
other components. And since this method returns the component, it is
displayed twice.

Yes, but it is probably not simple and certainly involves changing the
implementation of WATree. You could do it using JavaScript, e.g. with
script.aculo.us and a scroll-to effect.

Cheers,
Lukas
