Hi!

Is there the possibility to add images from an web url (best with update frequence parameter)? I want to display and update this animated GIF in a widget.

Hi, you can uses script code "DownloadFile" to get this gif image
for excample, this bing widget can download the wallpaper file from url and display: http://www.xwidget.com/xwidget/widgets/ ... 8/240.html

Thanks!

Sadly I can't script but I looked into your linked widget and with some trial and error I cropped the code to this:

Code:
var filename = widgetpath + "radar.gif";
var url = "http://www.meteogroup.co.uk/meteo/automatic-gif/radar.teaser/radar_de_teaser.gif";

function DownLoadInit()
{
     text_update.text = "Updating...";
     text_update.visible = true;
     downloadFile( url,filename,"DownLoaded");
}

function DownLoaded(succeed,filename,filesize)
{
   text_update.visible = !succeed;
   if( succeed )
   {
     gif_radar.src = "";
     gif_radar.src = filename;
   }
   else
   {
      text_update.Text = "Update Failed!";
      settimeout( "h",3000 );
   }
}


This works nice, the image gets loaded from the url and displayed in the widget.

Now I have to find out how to handle the saved gif-file (as xwidget does not overwrite it) and how to update the image every x min... ^^
