How to handle doubleclick on ContentPanel header?

[koenjan]

Dear,

How can I handle a double click on the header of a ContentPanel?

I am trying to expand/collapse the panel (collapsible is set to true) when the user double clicks on the header, with the following code, but it's not reacting to a double click (also a ClickHandler is not working)... What is wrong?

panel.getHeader().addHandler(new DoubleClickHandler() {
@Override
public void onDoubleClick(DoubleClickEvent event) {
if (panel.isCollapsed()) {
panel.expand();
} else {
panel.collapse();
}
}
}, DoubleClickEvent.getType());

Best regards,
Koen

Very strange,

If I add an additional DomHandler, which is not doing anything, it is working

Now I have:

        panel.getHeader().addDomHandler(new DoubleClickHandler() {
            
            @Override
            public void onDoubleClick(DoubleClickEvent event) {
                // TODO Auto-generated method stub
                System.out.println("doubleclick DOM");


            }
        }, DoubleClickEvent.getType());
        
        panel.getHeader().addHandler(new DoubleClickHandler() {
            
            @Override
            public void onDoubleClick(DoubleClickEvent event) {
                System.out.println("doubleclick");
                if (panel.isCollapsed()) {
                    panel.expand();
                } else {
                    panel.collapse();
                }
            }
        }, DoubleClickEvent.getType());

Now, when I double click on the header I get both sysouts...
If I comment out the DomHandler, I don't get the "doubleclick" sysout...

Is this a bug???
