Close one widget when another is opened

MartynSmith — Wed, 29 Feb 2012 13:22:44 GMT

My goal is to have "WidgetA" and "WidgetB" mutually exlusive (in fact really I only want to allow one widget open at a time). I found some code from RSchleitin's "widgets communications" thread that Robert posted to close one widget when another is opened:

for each (var widgetId:Number in ViewerContainer.getInstance().widgetManager.getAllLoadedWidgetIds()) {     if(ViewerContainer.getInstance().widgetManager.getWidget(widgetId).widgetTitle == "WidgetA")     AppEvent.dispatch(AppEvent.WIDGET_CLOSE, widgetId); }

Inserted above code into "WidgetB" it works great and closes "WidgetA" when "WidgetB" is opened. I put the same code in "WidgetA" (except exchanged for "WidgetB").

The problem is, if I open "WidgetB" ("WidgetA" closes), then open "WidgetA" again, both widgets remain open. Any ideas on why this doesn't work both ways?

Martyn,

Are you putting that code in the init function or the widgetOpenedHandler? Because you should be adding it to the widgetOpenedHandler.

Robert- Thanks!

Hmm....I have it in the "init" function... There isn't a "widgetOpenedHandler" function (using the LayerList widget).

Martyn,

Then go to the WidgetTemplate in the code ad add one:

<viewer:WidgetTemplate id="wTemplate"                            open="wTemplate_openHandler(event)"                            width="300" height="300"                            closed="AppEvent.dispatch(AppEvent.TOC_HIDDEN)"                            minimized="AppEvent.dispatch(AppEvent.TOC_HIDDEN)">

            import com.esri.viewer.ViewerContainer;             protected function wTemplate_openHandler(event:Event):void             {                 for each (var widgetId:Number in ViewerContainer.getInstance().widgetManager.getAllLoadedWidgetIds())                 {                     if(ViewerContainer.getInstance().widgetManager.getWidget(widgetId).widgetTitle == "WidgetA")                         AppEvent.dispatch(AppEvent.WIDGET_CLOSE, widgetId);                 }             }
