Vaadin 6 / 7 / 8 Framework UI

Heyho community,

I have a timeline graph in bar chart mode in my application and want to get notifications if the user clicks on a or hovers over a certain bar in the graph.
Is there any way I can do this?

Thanks in advance,

René

I’m afraid adding click listeners to the graphs are currently not supported by Vaadin Timeline.

It would make a nice feature though, so please feel free to make a enhancement ticket about it in the vaadin trac.
(And if you are a
Pro
 member you can always Vote for the feature :wink: )

Hello Everyone,

Is the ticket raised for the events handling in timeline as i can see addListener method in timeline class but it seems its not working when i used below code?

Code snippet :
timeline.addListener(new Timeline.EventClickListener()
{
@Override
public void eventClick(EventButtonClickEvent event)
{
System.out.println(event);
Notification.show(event.toString());
}
});

I am currently using scatter for showing some data and planning to move timeline but i would need somethng like an click event as on click of each plot i need to process that event and do something …

any suggest on this…
