The UI Toolkit is a library summarizing the mechanisms and parts (widgets) required for creating a user interface (UI) on PSM. In addition to general widgets - such as, buttons and texts - (Figure 1), widgets unique to PSM are provided; these can each be customized and used.

The UI Toolkit Programming Guide explains how to implement an application that uses the UI Toolkit.
The UI Composer is a tool for easily creating a user interface that uses the UI Toolkit. By using this tool, the layout and properties of UI parts to be displayed on the device screen can be set. This tool can also output information regarding the specified layout and properties as a C# source code (Figure 2).
