Class StyleManager

Definition

Namespace:: Tizen.NUI

Assembly:: Tizen.NUI.dll

The StyleManager informs applications of the system theme change, and supports application theme change at runtime.
Applies various styles to controls using the properties system.
On theme change, it automatically updates all controls, then raises a event to inform the application.
If the application wants to customize the theme, RequestThemeChange needs to be called.
It provides the path to the application resource root folder, from there the filename can be specified along with any subfolders, for example, Images, Models, etc.
