Table of Contents - Legend Widget for FlexViewer 2.x

RobertScheitlin__GISP

All,

Here is the next in my line of widgets for the FlexViewer 2.x.

The legend portion of this widget is the same code as my dynamic legend widget so,

IT IS FOR ARCGIS SERVER 10 OR GREATER ONLY

This is just a simple TOC Widget that includes my dynamic legend component.
This widget also includes my enhancement for map service transparency,
right click context menu for zoom to make layer visible, and my scale
dependent renderer for the TOC checkboxes.

Khaled,

I don't have any other suggestions for this error:

1046: Type was not found or it is not compile-time constant: Tocitem

KhaledGh_

Thanks very much for your help; I'll recheck it and reply if I found any solution.

Edit: It worked; I had the name of the package as TOCWidget instead of TOC; I renamed it to TOC and worked smoothly.
It's a very good and nice tool.

Hi Robert,

Is there a way we could simply hide the layer names in TOC so that it does not appear. I have a string of booleans coming from java (1,0,1,0,0....) which matches the layer order structure in map service. The string keeps changing depending on different views user can choose (Views are basically extent) fromm a drop down. Each view has its own set of mandatory layers to be on/off. I was able to get the different layers on/off with views.
When I have 1 I use

      if (Arr=="1")
      {
       itm1.children.visible=true; 
                                                                  k=k+1;                                //For Group Layers
        
      }

and

                                    if (Arr=="1")
       { 
                                            itm1.children.children.visible= true;
                                                             k=k+1;               //For SubLayers in group 
       }

With the 0s I simply do not want them to appear on the TOC. How can I achieve this. I simply want to hide them and exclude from the TOC without using excludelayer property. Can some display property make this invisible.

Thanks.

My FlexViewer application is not fully honoring the ExludeLayer list in the TOC.xml configuration. I list layer numbers to exclude map service sub-layers. They are not loaded into the TOC, so the TOC is created properly, but when turning a layer on, or back on after it is turned off, all layers turned on, even the excluded layers.

RobertScheitlin__GISP

Scott,

That is actually the desired behavior of many users. If you want to eliminate those layers from the map than you have to use a layer definition.

Hi Robert,

By going here: http://gis.calhouncounty.org/FlexViewer2.4/index.html?config=config-toc.xml
And firstly clicking on the plus sign to the left of "Parcel Data" in the widget. A small pop-up shows up with the text, "Show Details". This only occurs on the top layer in the Table of contents.

Any way I can fix this or stop it from popping up?

Thanks for all of your great widgets; I use them all the time.

RobertScheitlin__GISP

This bug will be fixed in the 2.5 version of this widget coming soon.

ScottKiley

Robert, I must be missing the intention of listing sub layer numbers in the excludelayer tag of the TOCWidget configuration file. Please explain why you would want to limit layers of a map service in the TOC, but then not have that be honored when actually using the TOC to turn layers on and off.

To save server resources, I cannot make a map service for every application I create. So, I repeatedly use map services for many different applications. I need some way to limit the display of map services to specific layers. I have used the visiblelayers attribute of the layers tag in the past, and removed code to expand and collapse the tree in the TOC widget (essentially to mask the unnecesarry layers). I assumed you adding the ability to do this in the Widget configuration file met my needs.

Also, are you talking about using the definitionexpression tag when you refer to "a layer definition."? Because having one exhibits the same behavior. All layers of the map service still turn on.

Thank you for sharing all your work and knowledge.

RobertScheitlin__GISP

Scott,

The request from other users was the ability to have layers in the map that could not be toggled on or off by the user, hence them not being listed in the TOC but being turned on when the parent layer is turned on. I initially thought this idea pretty odd but was encouraged to add this ability by other users. Yes I was referring to definitionexpression for a layer that is of type="feature". As a developer it is hard to develop something that meets everyone's needs...

RobertScheitlin__GISP

All,

The new Flex Viewer 2.5 version of the TOC Widget is now available.

Version 2.5 - 12 Dec, 2011
* Added new Flex Viewer 2.5 Layer menu capability to TOC.
* Enhanced the visual appearance of the out of the box Flex Viewer 2.5 Layer options menu and added more options.
* You can choose to use esri's new description capability or the current functionality that the TOC Widget has for Metadata.

Hi, Robert,
thanks for the upgrade.

I am experiencing a problem with the widget:
- I have an operational layer in the config.xml file as type="feature" and the symbology of the layer is a set to categories with unique values (example .png file attached).
- the widget shows the legend of this layer wrongly, as it only shows the last category. I mean, the legend only has the symbol of the last category and nothing of the others.

Could you give some hints to solve it??, thanks a lot.

Coneje,

When you go to the REST Service Directory for this MapService and click legend does it appear in the results correctly?

For example if you enter a url like this in your browser:

http://MyServer/ArcGIS/rest/services/ParcelViewer/MapServer/legend

Good Morning Robert,

I hope your Holidays are going well.

I was wondering how complicated it would be to have the legend widget (or possibly a second widget) work as in this site :
http://maps.dublin.oh.us/Dubscovery/

My thinking is that the operational layers categories would still be located under the "More" button and when you select the category you get the individual window with the same functionality as shown on the site above.

One of the complaints we get from users is that since we have many operational layers it involves a lot of searching for their particular legend and transparency. It would be nice if they have all their options within one category as above.

I have attempted to contact them to see if they would be willing to share some code but have not received any responses. I understand this may be something to add to a wish list.

Have a great Holiday.

Nestor.

Hi, again,
In the path of the REST URL when I add legend I see the map service, but nothing about ¿legends?.
I must be missing something.

Anyway I send you what I see in the ArcGIS Desktop project, in TOC-Flex viewer and in the REST interface.

thanks

Coneje,

What version of ArcGIS Server are you using and what service pack number if any?

RobertScheitlin__GISP

Nestor,

I will not be adding this ability or producing another widget that has this ability and here is why. In RIA Web Maps the model (best Practice) is to design a map that is focused on one particular task or focus area. Web maps are not suppose to have LOTS of operational layers that force unskilled users to have to spend a lot of time searching for what they are looking for by going through a long list of layers, they should be focused and not have every available layer and the kitchen sink too. You should probably look at focusing your web map more and eliminating some operational layers.

Hello Robert,

I'm sure you have covered this, so hopefully it will be easy to respond. When I combine the TOC with the Selection Widget, Once the Selection widget is activated, all the FeatureLayers used in the Selection Widget get added to the TOC, preventing FeatureLayers from being added is an option for me, but I'd figured I'll check with you to see if there is a cleaner solution.

Thanks for your hard work

ConejeSapiens

In the Desktop version-> 10.0
In the Server version-> I think it is the same, but where can I see it?, where in the Server Manager web?

Coneje,

Go to your http://YourServer/ArcGIS/rest/services and it should look something like this:

RobertScheitlin__GISP

Harold,

Do you have the source code for the selection widget? The way esri is handling this is adding "hiddenLayer_" to the name of the layer.

ConejeSapiens

ok, Robert,
the version I see in this URL is 10.0

Coneje,

You might not see all the symbology properly in the TOC Widget until you apply at least service pack 1 to ArcGIS Server. There are 3 service packs out for ArcGIS Server 10. I would recommend that you apply SP3 now.

ConejeSapiens

ok, we will try with an upgrade of the service pack in the server.

Thanks!!

Hi again, Robert,
just telling you that we upgraded the server to SP3 and the problem is solved.
That was the solution, as you suggested.

Thanks, really!!

Hi Robert,

I have layers that are only visible at certain scales. Is it possible to have these layers only show in the legend when they are visible in the map?

Thanks for your help!

Ashley

RobertScheitlin__GISP

Ashley,

Scale dependent layers are respected by the legend and are visible but disabled (grayed out) and have a special checkbox icon like ArcMap that shows they are scale disabled. You can see this behavior in the live demo site of my widget (look at Parcel Data).

AshleyPeters

Robert,

I noticed that. I'd like for the scale-dependent layers to not show in the legend until they are visible on the map. That may not be possible or easily accomplished. I'm still pretty new at this.

Thanks for your quick reply!

Ashley

MattiasEkstrom

Robert,
I know you've been asked about legends for WMS layers before, and that's not your priority now.
I'm thought I could take a look at this my self, as a first step I would be happy just to be able to add a single image with a hard coded imageURL for each WMS layer.
Can you give me some hints how to accomplish this?
My guess so far is that I might start with something like:

}else if (m_layer is WMSLayer){

in the getLegendData function in TocMapLayerItem.as

but then I'm lost 😃
