Editing Banner in Sample Flex Viewer

[SandeepTalasila]

I want to edit the banner of the sample flex viewer, I would like to show the sub title in two lines, instead of one line. Because the width of the banner is increasing if my subtitle is too long. I have tried line breaks used in XML but it didn't work. I also tried adding two subtitles, but still I cannot get to the result. Please let me know any ideas.

Thanks,
Sandeep.

Darryl,

   You have to set the width of both the banner.mxml and the controller.mxml

1. in the index.mxml change the existing line to this one

<controller><Controller id="control" left="20" top="20" right="30" width="100%"/></controller>

2. in the Banner.mxml add

width  ="100%"

to the top canvas.

Hi
I'm trying to use parameters from the URL to populate the subtitle string.   I have a getURLParameters function which I use in MapManager.mxml (see below) but don't know how to call this in Banner.mxml to redefine the subtitle string.   I guess I need to add this function to Banner.mxml and write another function that calls it?  Any help would be much appreciated

Thanks

Ian

            private function getURLParameters():Object
            {
                var result:URLVariables = new URLVariables();

                try
                {
                    if (ExternalInterface.available)
                    {
                        // See http://livedocs.adobe.com/flex/3/langref/flash/external/ExternalInterface.html
                        var search:String = ExternalInterface.call("location.search.substring", 1);
                        if (search && search.length > 0)
                        {
                            result.decode(search);
                        }
                    }
                }
                catch (error:Error)
                {
                    Alert.show(error.toString());
                }

                return result;
            }

Ian,

   You can actually do it all in the MapManager.mxml in the mapLoadComplete function.

I have setup the url parameter as "sTitle" so it would look like (http://gislap134/flexviewer/index.html?sTitle=hi%20world).

private function mapLoadComplete(event:MapEvent):void
      {
       SiteContainer.dispatchEvent(new AppEvent(AppEvent.LAYER_LOADED, false, false, null));
       
                try
                {
                    if (ExternalInterface.available)
                    {
                     var result:URLVariables = new URLVariables();
                        // See http://livedocs.adobe.com/flex/3/langref/flash/external/ExternalInterface.html
                        var search:String = ExternalInterface.call("location.search.substring", 1);
                        if (search && search.length > 0 && search != "debug=true")
                        {
                         result.decode(search);
                         var xUrlParam:String;
                         if (result["sTitle"]){
        xUrlParam = result.sTitle; 
                             SiteContainer.getInstance().controller.banner.subtitle = xUrlParam;
                          } 
                        }
                    }
                }
                catch (error:Error){}
            }

Thanks Robert, that is just what I needed - changed your param variable to mine and it worked first try!    Sending you a virtual cerveza, have a great weekend.

Thanks Robert for the tip change the banner width to 100% of page.

Greatly appreciated!!

I have been unsuccessful at changing the subtitle color in the default.css file.

I have tried the following:

color: #FF0000;
color: 0#FF0000;
color: red;
fontColor: #FF0000;
fontColor: 0#FF0000;
fontColor: red;

Anyone have any other suggestions?

[KeithBornhorst]

Your default.css additions...

.BannerSubtitle
{
 color:#ff0000;
}

... are being overriden by code in UIManager that sets the subtitle color to the title color.

// UIManager.as ~line 203
var cssStyleDeclarationBannerSubtitle:CSSStyleDeclaration = new CSSStyleDeclaration(".BannerSubtitle");
if (numberOfStyleColors > 4)
{
     cssStyleDeclarationBannerSubtitle.setStyle("color", titleColor);
}
topLevelStyleManager.setStyleDeclaration(".BannerSubtitle", cssStyleDeclarationBannerSubtitle, false);

Comment that out and your subtitle should take whatever stylings are assigned to it in default.css.

Cheers,
K
