Add a component to ScrollPane in Java

Hi All,

 

I am very new to Pivot and just starting to play with it. I have a
ScrollPane declared in the wtkx file as the following:

 

 

          <ScrollPane wtkx:id="serverTreeScrollPane"
verticalScrollBarPolicy="fill_to_capacity"
styles="{backgroundColor:'#E8E8E8'}"> 

          </ScrollPane>

 

And have the following code in Java to add a link button to the
scrollpane:

 

 

          LinkButton l2 = new LinkButton("Test");

          serverTreeScrollPane.add(l2);

 

When I run the code, nothing shows in the scrollpane. For BoxPane
(<BoxPane wtkx:id="serverTreeScrollPane" orientation="vertical">), the
button was added just fine.

 

What did I do wrong?

 

Thanks,

 

Yunlong

A scroll pane doesn't know what to do with arbitrary components added to
it via add(). You need to tell the scroll pane specifically what to do
with your component. For example, try calling:

 

  serverTreeScrollPane.setView(l2);
