Detailed Description

Handles themes (the look and feel).

Using themes makes it easier to change the look and feel of an application. ThemeManager is the central for all used themes. Every variable of a class derved from UiTheme will be registered here and can become active when required.

This class can only be used in one variable at a time. So do not initialize it more than once, but it is required once, if you use themes.
