ClickListener on Panel's caption bar

Is there a way to add a ClickListener to the caption bar portion of a Panel?

It looks like the portion of the panel that is interesting is enclosed in a <div/> with class of 'v-panel-captionwrap'.

class="v-panel-captionwrap"

Here is the full stanza.

<div class="v-panel-captionwrap" style="margin-top: -37px;">
  <div class="v-panel-caption v-panel-caption-color1 v-panel-caption-margin10">
    <span>This is where panel caption would be</span>
  </div>
</div>

This <div/> is enclosed in the Panel's v-panel <div/>.  If you set the id on the panel to 'MyPanelId'  [Panel]

Panel myPanel = new Panel(...);
myPanel.setId("MyPanelId");

the resulting stanza is like what is shown below:

<div class="v-panel v-widget color1 v-panel-color1 margin10 v-panel-margin10"
     id="MyPanelId"
     style="overflow: hidden; padding-top: 37px; padding-bottom: 0px;">

Is there a way to make use of this information to attach a click listener to the 'v-panel-captionwrap' section of this specific panel?  

I prefer not to attach the ClickListener to the entire panel unless necessary.

Thanks in advance, 

John

In lieu of a better solution...

Use case:  

• toggle the contents of a panel when the caption bar is clicked.

The solution (kludge?) is to encapsulate the ClickListener and toggleable behavior in a supporting class called PanelCaptionBarToggler.

Usage:

Panel myPanel = new Panel(...);
new PanelCaptionBarToggler<Panel>( myPanel );

Implementation:

public class PanelCaptionBarToggler<T extends Panel> {
    private T panel;
    private Resource cacheIcon;
    private float COLLAPSED_WIDTH_PIXELS = 400f;
    private static final int CAPTION_BAR_HEIGHT = 30; 
    public PanelCaptionBarToggler(T panel) {
        this.panel = panel;
        panel.addClickListener((clickEvent->{
            if(clickEvent.getRelativeY()<CAPTION_BAR_HEIGHT) {
                toggleContent();
            }
        }));
    }

  
    private void toggleContent() {
      panel.getContent().setVisible(!panel.getContent().isVisible());
        if (!panel.getContent().isVisible()) {
            cacheIcon = panel.getIcon();
            panel.setIcon(FontAwesome.ARROW_CIRCLE_DOWN);
            panel.setWidth(COLLAPSED_WIDTH_PIXELS, Unit.PIXELS);
        } else {
            panel.setIcon(cacheIcon);
            panel.setWidth(-1, Unit.PIXELS);
        }
    }
 
}

Q: How to add a cursor to the caption bar of a panel?

A: For anyone interested, to add a cursor of 'pointer' to the caption bar:

.v-panel-caption-[b]showpointer[/b] {
        cursor: pointer;
    }

Then with your panel:

Panel myPanel = new Panel(...);
myPanel.addStyleName("[b]showpointer[/b]");
