In my case with the nested layers if I did that it would take up half the screen.  Plus some layer names are really long (I know bad UI but that is how it has to be.)  It was also be nice that if you hovered the mouse it would show it to you similar to what the windows file browser does.  It would also be nice if MapSwitcher was sizable. I guess I just keep running into that the viewer is really just for small maps of a few layers. ... View more

I had tried the registry MS thing a number of ways with no luck. I was able to get a copy of the new 10.1 SP1 install and that worked! Now if I can get the ports opened up..  Even with windows firewall off still no one can get in. Thanks. ... View more

Ok here you are.  It works by using toc.excludelayers.  At the beginning all layers are in the exclude.  Then when a user wants to add a layer I actually remove it from the exclude list I have.  To remove from the TOC I add it back to the list of excluded layers.  The Visibility check boxes in both TOCs do stay synced, order is also synced when using the base code (my application gets around this but be careful if you do not want this) . First I made a copy of MapSwitcherWidget and called it MapSwitcherWidget2.  I then had to change a few other files to allow the drag and drop mostly.  Overall very few changes to the original code. There is still test code in here commented out.  If I missed anything or questions just let me know. ------------------------------ Drag and Drop Code (and other code parts are seen here also) in MapSwitcherWidget2.mxml    private function dragDropHandler(event:DragEvent):void    {     /*Alert.show(event.dragSource.dataForFormat('text') as String);*/     if (templist.getItemIndex(event.dragSource.dataForFormat('text')) != -1)     {      templist.removeItemAt(templist.getItemIndex(event.dragSource.dataForFormat('text')));     }    }       private function dragEnterHandler(event:Event):void    {     var dropTarget:Button=Button(event.currentTarget);     // Accept the drop.     DragManager.acceptDragDrop(dropTarget);        }    /* drop on the toc button itself because of the autohide  - i later took out the autohide and then moved this to the border container*/    <s:HGroup id="mapLayersContainer" gap="9">         <s:Button id="opLayersButton"                   height="100%"                   label="{opLayerListButtonLabel}"                   rollOut="startHideTimer()"                   rollOver="opLayerListButton_rollOverHandler(event)"                   visible="false"       dragEnter="dragEnterHandler(event)"       dragDrop="dragDropHandler(event)"/> in TocItemRenderer.as protected function onCheckBoxMouseMove(event:MouseEvent):void {   // Get the drag initiator component from the event object.   var dragInitiator:CheckBoxIndeterminate=CheckBoxIndeterminate(event.currentTarget);

        }     } Changed this so it used the text instead of the checkbox for the drag.  The drop handler is where it ignores draggin the checkbox or down arrow (these can be dragged but then you have to change the code to get the name of the layer). protected function onTOCItemMouseMove(event:MouseEvent):void {   // Get the drag initiator component from the event object.   var dragInitiator:TocItemRenderer=TocItemRenderer(event.currentTarget);

I have now finished adding   Auto Add to Working Set TOC on Visible Checkbox Check in other TOC   Ability to add to the Working Set TOC by drag and drop from other TOC   A button to remove a layer from the Working Set TOC   A Save Current Working Set TOC feature that saves the current state to a local txt file   A Load a Saved Working Set TOC feature that loads a saved TOC state from a local txt file I will give the code changes required if anyone wants them.  It has not been cleaned up at all. Thanks for all the help. ... View more

I meant in the viewer application.  The Widgets tab that has the icons for each widget.  The new ones are not in there. ... View more

Thanks Anthony.  Not exactly sure what you mean though.  I have been trying to code the ability to drag a layer from the main large TOC to the Working Set TOC but have not been able to figure it out.  It never lets me drag anything.  I do not see in your code how that works.  I see the part of the map accepting the drag but nothing that allows the drag.  It is just beyond me as a newbie I guess. I have it working where a user checks the visible box in the main TOC and it shows up in working set.  I am now looking into a way to remove a layer from the Working Set TOC (through an icon or menu item I guess).  I also am going to try and find a way to save the list of layers out to a users computer and then be able to add the list back in (saving the session state of the Working TOC basically).

I am at a large govt agency so all the servers are handled by an outside contractor and I do not get to have much insight into this.  It sounds like they are trying just one large machine but as a former server room guy I have my doubts, lets just say that. I did end up creating a "Working Set TOC".  It automatically adds any layer that is made visable during the session.  I might also add a Add To option in the main large TOC.  The dragging is a cool idea but probably beyond my capabilities as a new Flex guy (I might look into it as a challenge).  If you want to see how I got this Working Set TOC to work I posted the code as part of this post - http://forums.arcgis.com/threads/72877-Why-is-Legend-Widget-still-updating?p=255217#post255217 We do have plans for a search function, the autocomplete would be cool, I will have to look into it.  We want to add the saving of session info but the policy people will not let us. Thanks for the ideas. ... View more

I have gone through every line of every file that has to do with the TOC and legend and I still can not find the spot where the legend knows a layer has been turned on.  Anyone know where this happens?  It is not an event listener since it still works without it somehow. ... View more

I am not sure if this will help but when I did a Python Excel script there was a way to check the Excel "cell_type" which is equal to 0 when the cell is blank. ... View more

Thanks Brian.  This is actually exactly what we have now.  But it is still getting really long with the 300 or layers in there so far.  We are looking into a "See More" button to limit the number of layers displayed in each subcategory.  Only bummer there is that we will then have to add each layer one by one to the list instead adding the whole map at once. I looked at UI options all day Friday but did not see anything I wanted.  Maybe using carousels or as someone drills down the current structure appears at the top.  But nothing seems to be a good fit so far. The idea I have now is to leave the TOC like yours and then create a "Working Layers" widget.  This would be a TOC for just the current session.  That way people do not have to go hunting back through the huge list just to toggle layers.  Whenever a layer is turned on in the big list it automatically gets added to the Working Set.  A user could also click Add to Working Set in the TOC without turning it on.  Anyone done anything like this?
