Change icon dynamically from program code?

[kevin1]

Can I change the widget icon dynamically from my app/program program code (not in the webpage/javascript)?  Something like this, which doesn't seem to work:

Code: [Select]

if(GarageDoorClosed){
 Program.Parameter("Widget.DisplayIcon").Value = "http://cdn.device-icons.smartthings.com/doors/garage/garage-closed.png";
}esle{
 Program.Parameter("Widget.DisplayIcon").Value = "http://cdn.device-icons.smartthings.com/doors/garage/garage-open.png";
}

A time I have made one modification in the widget icon gestion.
If the icon name (Widget.DisplayIcon) contains _off it's replace automatically replace by _on when the widget receives level change to 1. So only you have to put the 2 icons in the same folder and specify the off icon in the parameter
