Change the subtitle of flex viewer dynamically from widget

SaugatJoshi

Hi all,

Is there a way I can change the subtitle of the Flex viewer dynamically? I have a list of tags in a combobox eg: tag 1 , tag 2 and so on in the LayerList widget. When i click on tag 1 it changes the layer visibility and now I want the tag name appear as a subtitle in the Flex viewer. How can I achieve this.
The snippet below does not seem to work. I must me missing something here....

configData.ViewerUI.subtitlle.value

Thank you.

Saugat,

This is what you need:

AppEvent.dispatch(AppEvent.SET_TITLES, { title: "Hello", subtitle: "World" });

Robert, Where does the addlistener go for this dispatched event?

Thanks.

Saugat,

You don't have to add one the viewer already is listening for this event.

Robert thanks,

I am using viewer 2.3.1 and do not see it defined anywhere.

Saugat,

OK, you didn't tell me Flex Viewer 2.3.1... I will have to look how to do this in 2.3.1

Robert,

For this I think in the layerList widget.

ViewerContainer.dispatchEvent( new AppEvent("subtitleChanged",subtitleP);

Then in init() of Mapmanager.mxml

ViewerContainer.addEventListener("subtitleChanged",changeSub);

,and

private function changeSub(event:AppEvent):void
   {
    configData.ViewerUI.subtitlle.value=event.subtitleP.toString()
   }

Do you think this is a correct way?

Saugat,

No there is nothing that is listening for a change to the configData.ViewerUI.subtitlle.value you would have to add:

ViewerContainer.addEventListener("subtitleChanged",changeSub);

to the headerControllerWidget.mxml and add the changeSub fuction that would change the

bannerSubtitle.text =event.subtitleP.toString();

Thanks Robert,

Solution works fine.
