Really close a widget Pt. deux

TylerWaring — Wed, 08 Jun 2011 01:39:15 GMT

Greetings. This is a continuation of the origional post "Really Close a Widget" (http://forums.esri.com/thread.asp?c=158&f=2421&t=302669). Great stuff. However there are a few conceptual leaps required by the solution that I am not yet equiped to make.

The Solution:
public function closeWidget(id:Number, url:String):void
      {
       if (widgetTable.containsKey(id))
       {
        var widget0:IBaseWidget = widgetTable.find(id) as IBaseWidget;
        var wObj0:DisplayObject = widget0 as DisplayObject;
        widgetTable.remove(id);
        if(widgetBox.contains(wObj0))
         widgetBox.removeChild(wObj0);
       }


       if (moduleTable.containsKey(url))
       {
        var modInfo:IModuleInfo = moduleTable.find(url) as IModuleInfo;
        moduleTable.remove(url);
        modInfo.unload();
       }
      }

Conceptual Leaps:
1. Where does this funciton belong.
2. How do you reference the widgetTable and moduleTable
3. How do you reference the widgetBox.

I realize that this is probably pretty complex to explain so any more hints to get me in the right direction will be greatly appreciated. ViewerContainer.dispatchEvent(new AppEvent(AppEvent.WIDGET_CHANGE_STATE, {id: this.widgetId, state:WidgetStates.WIDGET_CLOSED})); is not the appropriate way to close the widget if you wish to reloas the config file.

Thanks,
Tyler

Tyler,

If you put this function in the WidgetManager.mxml it will have the links it needs to the widgetTable, moduleTable, and widgetBox.

Thanks Robert. Where would my projects be without your replies to my and other people's posts? I have loaded this function into the WidgetManager but widgetBox is not declared in the WidgetManager (Flex Viewer 2.2). Any suggestions?

Tyler,

I did not write that code for the new flex viewer and did not consider that the widgetbox is no longer in the WidgetManager.mxml but now the widgetContainer is a group in the WidgetContainer.mxml and is very different now.

Is there a way to reference the widgetBox or is this line of logic a not the way to truely close a widget? I am having issues with my program because i can not really close a widget. Thanks. Tyler

O.K.
I think that I may have crossed information from two separate versions of the Sample Flex Viewer or misdiagnosed/complicated the issue. There was a flaw in my logic and research that revealed itself last night. I now see that ViewerContainer.dispatchEvent(new AppEvent(AppEvent.WIDGET_CHANGE_STATE, {id: this.widgetId, state:WidgetStates.WIDGET_CLOSED})); does close the widget, at least to the extent I need for my program. I really had a different problem and some testing and research indicated the design I was implementing was flawed from the get go. A quick redesign has me back on track. Thanks for bearing with me.
