Determining +whether to display home screen or full screen

A widget enabled for the home screen has two views, home screen +view and a full screen view. You must implement a function in your widget +that determines in which view to display the widget and call that function +in response to communication from the home screen.

The home screen communicates with the widget when users interact with the +home screen. Communication between the home screen and the widget occurs at +the system level, so it happens automatically. When the widget receives communication +from the home screen, it fires the following events:

onload() and onshow() when +users add a widget to the home screen.
onshow() and onresize() when +the mobile device user selects a home screen widget to launch it in full view.
onshow() and onresize() when +the home screen moves from the background to the foreground.

To determine which view to display

Write JavaScript code +that determines the current screen size and uses that value to initialize +either the home screen view or the full screen view.
For example, the +following functions set a threshold value of 150 pixels to determine whether +to display the widget in full screen view (initFull) +or home screen view (initHomeScreen).
```
function setViewMode(){
+   var isInHSView = isHSViewMode();
+	
+   if ( isInHSView ) {
+       initHomeScreen();
+		   
+	 } else {
+		   initFull();
+   }
+}
+
```
```
isHSViewMode: function() {
+	   var size = this.getScreenSize();
+	   return ( size.height < HS_VIEW_TRESHOLD );
+}	
+
+
```
```
HS_VIEW_TRESHOLD = 150;
+
```
Call the setViewMode() function +in response to onload(), onshow(), and onresize() events +fired by the widget UI.
For example, the following HTML code calls setViewMode() in +response to these events.
```
<body id="body" onload="setViewMode();" onshow="setViewMode();" onresize="setViewMode();">
```
