-In your app you have to do just three things,\\ \\
-. Load the Script with
-    app.LoadScript("DlgNewFile.js")
-. Create a Button to call the Dialog and add it to the layout
-    btn = app.CreateButton( "Create a new File", 0.3, 0.1, "Alum" );
-    btn.SetOnTouch(CreateNewFile);
-    lay.AddChild( btn );
-. Write a function to call the Dialog
-    function CreateNewFile()
-    {
-        // write the path where you want create the file
-        DlgNewFile = new NewFileDialog("/mnt/sdcard/");
-        DlgNewFile.Show();
-    }
-Or you can use this Example.
-<code Javascript exampleapp.js>
-//Called when application is started.
-function OnStart()
-{
-    app.LoadScript("DlgNewFile.js")
-    lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
-    btn = app.CreateButton( "Create a new File", 0.3, 0.1, "Alum" );
-    btn.SetOnTouch(CreateNewFile);
-    lay.AddChild( btn );
-    app.AddLayout( lay );
-}
-//Create a new Dialog
-function CreateNewFile()
-{
-    // write the path where you want create the file
-    DlgNewFile = new NewFileDialog("/mnt/sdcard/");
-    DlgNewFile.Show();
-}
