The SetScreenMode method sets the screen mode. It could be full screen mode “Full” or normal screen mode “Normal” or “Default”.

 app.SetScreenMode( mode );

//Called when application is started.
function OnStart()
{
	//Create a layout with objects vertically centered.
	lay = app.CreateLayout( "Linear", "Vertical,VCenter,FillXY" );	
 
	btnFull = app.CreateButton( "Set full screen", 0.5, 0.1 );
	btnFull.SetMargins( 0, 0.05, 0, 0.05 );
	lay.AddChild( btnFull );
 
	btnNormal = app.CreateButton( "Set normal screen", 0.5, 0.1 );
	btnNormal.SetMargins( 0, 0.05, 0, 0.05 );
	lay.AddChild( btnNormal );
 
	//Set function to call when button pressed.
	btnFull.SetOnTouch( btn_OnFullTouch );
	btnNormal.SetOnTouch( btn_OnNormalTouch );
 
	//Add layout to app.	
	app.AddLayout( lay );     
}
 
function btn_OnFullTouch()

    app.SetScreenMode( "Full" );
}
 
function btn_OnNormalTouch()
