You can run the NOV Theme Builder in any of the following 3 ways:

1. Run the Nevron.Nov.ThemeBuilder application that comes with NOV
2. Open the User Interface > Appearance > Theme Builder example that comes with NOV and click the Open NOV Theme Builder button of the example.
3. Use the following piece of code in any NOV application:

// Create a Theme Builder widget
NThemeBuilderWidget themeBuilderWidget = new NThemeBuilderWidget();

// Create and open a top level window with the Theme Builder widget
NTopLevelWindow window = NApplication.CreateTopLevelWindow();
window.StartPosition = ENWindowStartPosition.CenterScreen;
window.PreferredSize = new NSize(1000, 700);
window.SetupApplicationWindow("NOV Theme Builder");
window.Modal = true;
window.Content = themeBuilderWidget;

// Open the window and show the Theme Builder start up dialog
window.Open();
themeBuilderWidget.ShowStartUpDialog();

In the NOV Theme Builder application, click the New button to create a new theme based on an existing theme and the Open and Save buttons to open and save NOV UI themes.

To load a theme created with the NOV Theme Builder in your application use any of the following static methods of the NTheme class:

• FromFile - returns a promise that reads and loads a theme from file.
• FromResource - loads a theme from resource.
• FromStream - loads a theme from a stream.

To apply the loaded theme, call NApplication.ApplyTheme in the entry point of your application.

To save a theme programmatically use the following methods of the NTheme class:

• Save(NFile file) - saves the theme to an NFile. Returns a promise that gets fulfilled when the file is saved.
• Save(Stream stream) - saves the theme to a stream.
