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.

Mattias,

I looked into this once and just didn't have the time to commit to it. As the TOC Widget uses a tree and tree item renderers You can't just stick an image into it. I don't have any advice for you on this right now.

MattiasEkstrom

Robert,
I understand, thanks anyway for this great widget.
I found a way to add show meta data button for WMS layers that shows a modified details window with the legend image, I'll settle for that for now.

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

I modeled the implementation for excluding graphics layers to accomplish this, thanks

RobertScheitlin__GISP

Harold,

Glad you got it working I had intended to respond but must have gotten side tracked. I don't use the selection widget so I could not respond without investigating Marks code.

MattiasEkstrom

Robert, did you ever got that proxy support code that Jeremy Moore mentioned in an earlier post?
What I can tell it isn't implemented yet, right?

Jeremy could you share some code?

I would like just that part of the code because I'm using my own customized version of this TOCwidget.

EDIT:
I think I found a solution my self, I've only tested this a little bit in my own application that only has DynamicLayers in the legend, but it seems to work...
I made just a few changes to the getLegendData function in TocMapLayerItem.as

  private function getLegendData(m_layer:*):void
  {
   if (_legendDataLoaded)
    return;
   _legendDataLoaded = true;
   
   if (m_layer.hasOwnProperty("url")){
    const url:String = m_layer["url"];
    if (url === null)
     return;

Hi, Robert,
thanks for the widget.

I am experiencing a problem with the widget:

The legend for the layers that have more than one full symbolism is not displayed in the widget.

I use FlexViewer version 2.3.1 and TOC version 2.3.7.2.
I read that can be for the Tree component Scroll adobe.
I wonder if this error was fixed for version 2.3.1 FlexView.

If it was resolved I would like the 2.3.x version of TOC where the solution or the way
to implement it in version 2.3.7.2 because I do not upgrade to FlexViewer version 2.5.

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

Alexander Mena.
Procalculo.

RobertScheitlin__GISP

Alexander,

Support is only offered for the latest version of my widgets. The code attached is what I believe to be the 2.3.9.2 version. You really have to watch for new releases, as bugs are constantly fixed and enhancements made to my widgets. All of the below happend for FlexViewer 2.3.1 version of the TOC widget since 2.3.7.2:

Version 2.3.9.2 - 1 August, 2011, 8:40 PM
* This probably will not happen ever again but I wanted to have a good stable Flex Viewer 2.3.1
version of this widget available so I have added the compiled version with the memory leak fix
and the follow-up fix for the disapearing labels.
* Uncompiled code is written for Flex Viewer 2.4 ONLY!

Version 2.3.9.1 - 19 July, 2011
* Fixed a item alignment issue in the TOC

Version 2.3.9 - 12 July, 2011
* Added exit code for people still using ArcGIS Server 9.3.1 or lower so that the Generating Legends
message was not be stuck on the widget. (Lengend swatches will not be gerated for Server 9.3.1 or lower).

Version 2.3.8.6 - 6 July, 2011
* Added Ability to collapse ALL legend symbology
* Added new context menu for "expand all layers" and "collapse all layers"
* Changed the expand and contract icon for legends to the plus and minus (like in ArcMap).

Version 2.3.8.5 - 1 July, 2011
* Added Ability to collapse legend symbology is more than one symbol is present for a layer
* Added ability to have all collapsible legend symbology collapsed at startup based on
TOCWidget.xml setting.

Version 2.3.8.4 - 23 June, 2011
* Slowed down mouse wheel scroll speed
* Added generic legend support for Dimension, Annotation, Raster Catalog, and Tiled Raster Basemaps
* I am not real happy with the Tiled Raster Basemaps but the way esri currently returns legend info
is not real conducive to legend generation. Maybe 10.1 of server will fix this.

Version 2.3.8.3 - 21 June, 2011
* Fixed issue with excluding multiple sublayers of a dynamic map service.
* Added a busy indicator and message for large complicated legends.

Version 2.3.8.2 - 21 June, 2011
* More optimization of the layout to use less vertical and horizontal space.

Version 2.3.8.1 - 20 June, 2011
* Fixed Horizontal clipping issues when tree leafs were collapsed.

Version 2.3.8 - 11 June, 2011
* Fixed Horizontal and vertical scrolling issues.
* Enhanced layout of TOC swatches and checkboxes.
* Cleaned up lots of unused portions of the code.
* TOC Item label is gray when item is scale dependent.

Version 2.3.7.2 - 10 June, 2011
* Fixed ZoomToMakeVisible context menu when using cached/tiled base maps.
* Feature layers now only have one checkbox at the parent map service that show
Scale dependency and has context menus.

Don't forget to click the top arrow (promote) as shown below:

Thank you Robert for you reply, but.

Where I find the lastest version without compiling for FlexViewer 2.3.1? I need the code to fix the scrolling.

I have customized the widget. I try to replicate the code for Scroll of the version 2.5 but remains the same.

<s:Scroller id="scr" width="100%" height="100%">
    <s:Group>
     <s:layout>
      <s:VerticalLayout gap="1"/>
     </s:layout>
     <s:HGroup id="boxMessage"
         width="100%"
         includeInLayout="false"
         visible="false"
         verticalAlign="middle"
         horizontalAlign="center">
      <mx:Image id="swfMessage"
          source="widgets/TOC/assets/images/loader.swf"/>
      <s:Label id="txtMessage"
         width="90%"
         text="{GeneratingLegendMsg}"/>
     </s:HGroup>
     <toccomp:TOC id="toc"
         width="100%"
         height="100%"
         labels="{[ZoomToMakeVisible,ExpandAll,CollapseAll]}"
         useesridescription="{UseNewEsriDescrption}"
         expanded="{expanded}"
         legendCollapsed="{legendCollapsed}"
         liveScrolling="false"
         variableRowHeight="true"
         tocMinWidth="{wTemplate.width - 45}"
         scroller="{scr}"
         loader="{boxMessage}"/>
    </s:Group>
   </s:Scroller>

Thank you.

Your out of luck there. I don't keep older versions of the source code only the compiled code.

Hi Robert,
I am currently using your "Table of Contents/Legend Widget Version 2.5 - For Flex Viewer 2.5". I am fairly new to flex, but was wondering if there is any way to make the widget grow dynamically as layers are added (like your dynamic legend widget)? Also, is there any way to remove the option to close the widget (and keep the option to minimize), as I do not want an icon for this widget on my toolbar.
Cheers,
Matt Giles

RobertScheitlin__GISP

Matt,

there is any way to make the widget grow dynamically as layers are added

No, if you are talking about the widget container itself.

is there any way to remove the option to close the widget

Not without change the code or using a custom widgetTemplateSkin

BarbRosenbaum

Hi Robert -

Your TOC contribution is great - in particular the integrated legend!

I'm wondering if you can think of a way to add a group heading to a set of services I might add to your TOC? I have several sets of services I'd like to group under headings in a tree structure. For example:

Map Contents
   group heading 1
     service x
       layer 1
       layer 2
     service y
     service z
   group heading 2
     service p
     service q
       layer 1
       layer 2

I know it's possible to do this with groups/headings in a MXD, but these are individual services and I don't want to cascade services. And I know this will confound the service/layer "move up and down" - but if I only needed to move the services within a group instead of moving groups?

Thanks,

Barb Rosenbaum

RobertScheitlin__GISP

Barb,

No, many have asked about this before and it would just completely convelute the whole TOC code and be a nightmare to manage.

MattiasEkstrom

Barb, and others who would like use groups/headings,

I want this functionality as well, and there is a way to do this without adding the functionality to the actual TOC-component. What I've done is that I've rewritten the widget to use several TOC-components, one for each group, and each TOC-components only include the layers belonging to that code. In the config-file I specify my different groups and which layers that belongs to them and then in the code I create an Accordion in my case with the different TOC-components.
See the attached image to get an idea of what it might look like, (I've also moved everything to the MapSwitcher and the operational layers box).
One big disadvantage is that I have to specify my layers twice, once in the main config file and once in the TOC-widget/MapSwither config file with the exact same name where I also specify the groups.

Unfortunately I won't be able to share my code as it is because I've made a lot of my own customizations and haven't been careful enough to comment all of my changes.
But the principle of using one TOC-compontent including only some specified layers for each group is a way to achieve groups/headings without to much coding.

I think my question may be the same / similar to Barbs above:

I have two wms layers from atlas of canada: protected areas and protected area labels.

I was wondering if theres any way to nest the two layers inside the TOC?
ex: Protected areas
            Protected Areas
            Labels

This is done in the example for Recreation
                                              - Trails
                                              - Facilities
                                              - Recreational Areas

BoCastillo

Robert,

First, thanks for the great widget and the hard work you have given the Flex community.

Is it possible to only expand the "top layer"? The problem is with using "extended=true" is that it expands lengthy layers such as "soils' and some layers don't expand at all. This is what I get by default in the first screenshot. What I would like to see is in the second screenshot.

Thanks,
Bo

Bo,

Open a new thread with this question and I will provide you the code that needs to be changed in the widgets source. This is not something that can be done without changing the code.

Thanks for your quick reply. I may not describe my question clearly. I would like to incoporate the TOC widget in the custom Flex API application instead of Flex Viewer application. I tried to do it. However, I did not figure it out how. Any suggestions would be greatly appreciated.

RobertScheitlin__GISP

Lixin,

You are on your own when you want to use the widget outside the Flex Viewer. That would require alot of decoupling from the Flex Viewer framework.

giuseppemolinario

Dear Robert,

I just saw that you made several revisions to your TOC! I also see that finally the ESRI team decided to copy it and offer some of the same tools.

So let me get this straight, your widget offers:

- Legend and TOC in the same place (a la arcmap)
- legends of classified rasters will appear
- WMS layers will appear (with legend?)
- transparency, move up and down, expand all (esri team didn't copy this one)

That's great! downloading and configuring it asap. I'll be back!

Thanks SO much!

Giuseppe

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.

RobertScheitlin__GISP

Giuseppe,

Actually, esri came up with the TOC menu first, I just added more options and made it look better.
WMS layer legends are not supported.

I do look for the Flex team to add a true TOC like this to the API and/or viewer as all the other APIs have this functionality (Silverlight, JS).

Actually, esri came up with the TOC menu first, I just added more options and made it look better.
WMS layer legends are not supported.

I do look for the Flex team to add a true TOC like this to the API and/or viewer as all the other APIs have this functionality (Silverlight, JS).

Hi Robert,

I might have been looking in the wrong place, but I can't find a full explanation of all the supported tags for the widget in both the config.xml file and the widget's own xml file. I'm asking because I want to make sure I use all the functionality that you've made available. Also, currently, I have two problems and a question about an implementation:

the icons for the "expand all layers" and "collapse all layers" are not showing
i am not seeing the "description" icon on any of my layer's menus, and am thinking I am missing how to enable it
the question is: (and I think i might know the answer) is there a way to change the width and height of the widget? or would that involve changing the code and recompiling it?

Thanks again,

Giuseppe
