Class Theme

Definition

Namespace:

Tizen.NUI

Assembly:

Tizen.NUI.dll

Basically, the Theme is a dictionary of ViewStyles that can decorate NUI Views. Each ViewStyle item is identified by a string key that can be matched the StyleName.

The main purpose of providing theme is to separate style details from the structure. Managing style separately makes it easier to customize the look of application by user context. Also since a theme can be created from xaml file, it can be treated as a resource. This enables sharing styles with other applications.
