How do you use classlib instead of taglib?

Question

Hi!
Perhaps a very novice-like question but I just don't know what to do. I'm trying to build a tree and want to use the function where you can click a treenode. The problem is that there is no tag for this but you have to use "setOnNodeClick" in the classlib instead. In the "PDK-portal" see "Examples/HTML Business Controls/" and then "Tree". Choose "Documentation" and in the new window "Tree.jsp". There you will see a complete jsp-file that will work as it is. If you then chose "Control API for Tree" you will see the controls for Tree and another code example for both taglib and classlib. The problem is that they are not complete and don't show how to incorporate the classlib. Is it used in a jsp file what so ever or in the dynPage??? If used in jsp file, is there any equivalent classlib-things to the content and page tags? And the line "Form form=(Form)this.getForm(); naturally renders an error since there is no such method in the example! I would like to see a full example in order to understand this.

You can use the classlib functions in either your java code or in the jsp.
Here is an example of using the classlib in jsp for the button control
<hbj:form id="myDisplayResultsFormId">
     <hbj:button id="buttonNewSearch"
            text="New Search"
            width="50"
            onClick="onButtonNewSearchClicked"
     >
     <% myDisplayResultsFormId.setDefaultButton(buttonNewSearch);  %>
     </hbj:button>
</hbj:form>
note the classlib function comes before the end of the button control but outside the button def.
Under the htmlb documentation you can access the control API which will list all of the taglib and classlib usages showing the equivalents. there is almost always an equivalent classlib for each taglib but there are lots of classlib methods without equivalent taglib entries.
Hope this helps
