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.

Phillip,

That is one of those unfortunate 99 bugs that the mx Tree component of the Flex SDK has, and I make reference to in my read me file.

Hi Robert,
Just downloaded and am testing 2.3.7 of the TOC. I had to incorporate a fix to allow grouped listings to function properly in the "latest" version of the TOC I am using (2.3.3). I have a different behavior on the 2.3.7 version of the widget. I cannot turn on a grouped sublayer - I click and it does not respond. I have attached a screen shot. It may relate to the "old" issue....Does the grouped layer code fix need to be applied to this new version also?
Any ideas?
Thanks

Eric,

I see the issue now with Groups of Groups and I am looking into this.

Nathan,

You should never publish a map service inside another map service. Just not good practice...

Done't get me started on this. I know. Not only is it friggen slow, it sucks balls for rendering legend and populating search widgets, identify etc.

Better allows me to manipulate which layers are turned on by default and which layers are turned off.
I've tried using visible layers tag in the config, but can't seem to get it to work. I'll post a new thread on it maybe.

Eric,

Issue is resolved in new version 2.3.7.1, but is caused me to depreciate the TOC updating based on programmatic layer visibility changes (Not a big deal for most people).

Robert,

This is spectacular, thank you for your hard work. Up and running on this site (with a few visual modifications). And thank you as always for the source code.

RobertScheitlin__GISP

All,

New version is available.

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.

EricVenden

Robert,
Is there an option in the latest config file for the TOC (2.3.8) to enable the inclusion of the entire layer name? It appears to be cut off. Seems to only happen at certain levels of the TOC (I have many groups of groups).... See attached.

It appears that if the "biggest" group is not expanded, then it cuts off the rest of the legend entries...as soon as I expand this biggest group (on my site it is floodplains) then the items display.

Thanks much for the improvements to this widget. It is greatly appreciated.
Thanks
Eric

Excellent widget!

I'm experiencing a little issue if the user close (collapses) all the layers, the layer name gets cut off, I checked the demo and also occurs there; the only difference is: un-collapsing (open) the layers revels the full layer name on the demo but not on my download. Any suggestions?

thank you

RobertScheitlin__GISP

Guys,

OK I am working on this issue.

RobertScheitlin__GISP

All,

Well this has been a sort of challenging release...Adding in the legend to the TOC. I have the issue with the horizontal clipping resolved now though. Go get the next version 2.3.8.1

DanielMx

Beautiful!

I have a silly question where does the tooltip for description and/or copyright information come from?

my *.xml has the tag <metadatatooltip>Show details</metadatatooltip>

I place text in the Description box when i created the service with ArcGIS manager, but i don't get the tooltip icon on the widget. Do i need to create metadata for the layer? any suggestions are very much appreciated.

Thank you!

RobertScheitlin__GISP

Daniel,

If you open the MXD and File > Map Document Properties there is a description text box there fill in that for the map service description. For each individual layer in the MXD you can right click on it in the TOC and choose properties and on the general tab there is a description there as well.

FrankRoberts

Thanks for the latest release! One additional feature to add to the config for the TOC widget would be a width and height of the widget. For some reason, I need to set my width really wide. It almost seems as if there is a larger than necessary boundary between the text of the legend and metadata button. I've attached an image to show you what I mean.

We all greatly appreciate your dedication to nailing this thing.

Thanks again,
Frank

Just noticed that no matter how wide I set the widget, I only get 1/2 the metadata icon on load. So if I set it to 500 or 600, for somereason only half the icon is displayed. I can manualy resize the icon, after load and all is well.

Frank,

Test this code for me and see if it fixes the issue for you.

Replace the existing measure function in the TocItemRenderer.as under TOC>toc>tocClasses

        override protected function measure():void
        {
            super.measure();
            const tocItem:TocItem = TocItem(data);
    
            // Add space for the checkbox and gaps
            if (isNaN(explicitWidth) && !isNaN(measuredWidth))
            {
                var w:Number = measuredWidth;
                if(tocItem)
                    if(w < tocItem.tocMinWidth)
                        w = tocItem.tocMinWidth - 20;
                if (_vbox && _vbox.numChildren > 0) w += _vbox.measuredWidth;
                measuredWidth = w;
            }
            if (!isNaN(measuredHeight))
            {
                var h:Number = measuredHeight + 5;
                if(_vbox && _vbox.numChildren > 0) h += _vbox.getExplicitOrMeasuredHeight();
                measuredHeight = h;
            }
        }

FrankRoberts

That code fixes the 1/2 icon on the load. However in my legend seems like it is forcing it to be pretty wide. See attached image.

Thanks for the code,

Frank,

Have you tried to change the width of the WidgetTemplate in the TOCWidget.mxml?

<viewer:WidgetTemplate id="wTemplate"
                           height="300"
                           skinClass="com.esri.viewer.skins.WidgetTemplateSkin"
                           width="440">

RobertScheitlin__GISP

Frank,

Try this instead:

        override protected function measure():void
        {
            super.measure();
            const tocItem:TocItem = TocItem(data);
    
            // Add space for the checkbox and gaps
            if (isNaN(explicitWidth) && !isNaN(measuredWidth))
            {
                var w:Number = measuredWidth;
                if(tocItem)
                    if(w < tocItem.tocMinWidth)
                        w = tocItem.tocMinWidth - 20;
                if (_vbox && _vbox.numChildren > 0 && _vbox.measuredWidth > w) w = _vbox.measuredWidth;
                measuredWidth = w;
            }
            if (!isNaN(measuredHeight))
            {
                var h:Number = measuredHeight + 5;
                if(_vbox && _vbox.numChildren > 0) h += _vbox.getExplicitOrMeasuredHeight();
                measuredHeight = h;
            }
        }

Robert,

Thank you very much for the information on the tooltip, It works now but only with the map service but not with the individual layers, I'm going to assume it's because I'm using *.msd instead of *.mxd and shapefiles instead of sde layers. I'm going to try with others services, thanks again.

Daniel

FrankRoberts

Robert the above code seemed to do the trick!

Thanks!
Frank

RobertScheitlin__GISP

All,

The changes that Frank and I tested are now compiled into version 2.3.8.2 as well as more code and layout optimization.

EricVenden

Has anyone experienced the following:

I have removed some layers from display in the latest TOC widget(2.3.8.1). Many of these layers are annotation - with annotation classes. If I click on a group in the TOC that has some layers removed to expand it and then click again to retract it, the Flash plug-in crashes.

Thanks

Eric,

By that you mean that you added several map service sublayer ids to the excludelayers element in the xml right?

EricVenden

Eric,

Correct - like this:

<excludelayers>
<excludelayer mapservice="Basemap">0</excludelayer>
<excludelayer mapservice="Basemap">6</excludelayer>
<excludelayer mapservice="Basemap">7</excludelayer>
<excludelayer mapservice="Basemap">8</excludelayer>
<excludelayer mapservice="Basemap">9</excludelayer>
<excludelayer mapservice="Basemap">10</excludelayer>
<excludelayer mapservice="Basemap">11</excludelayer>
<excludelayer mapservice="Basemap">12</excludelayer>
</excludelayers>

EricVenden

Robert,
I have attached an image of the REST service(REST.jpg). I am attempting to remove id's 1-10 and only allow the user to turn the "overall" group on/off. When I include layers 1- 10, I get the attached result (TOC_after.jpg). The original "state" of the TOC is the attached TOC_before.jpg

I understand if this widget is not intended to perform this type of operation.
Thanks for your time.
Eric V

Eric,

Thanks for the helpful info. I now have the issue resolved in version 2.3.8.3.
Also in your case you can optimize the xml by limiting to one line:

<excludelayer mapservice="Basemap">0,6,7,8,9,10,11,12</excludelayer>

Thanks for the quick turnaround on that Robert....works great. Curious - this latest version has a quicker scroll "response" when using the wheel on the mouse than the previous version. Is it possible to slow this down? I thought I remember a post with a reference to this?

Thanks again.
Eric
