Touch Screen (Stylus) Overview (Windows Embedded CE 6.0)
1/6/2010
Touch Screen (Stylus) functionality in Windows CE 5.0 provides support for stylus input. Many OS designs rely on stylus input rather than mouse input to enhance portability. Applications, however, process stylus events as a click of the left mouse button only, so the Touch Screen (Stylus) Catalog item does not provide as broad a range of pointer capabilities as the Mouse Catalog item. But, a great deal of input functionality, such as the Software-based Input Panel, Handwriting Recognizer Engine (HWX), and Transcriber Handwriting Recognizer Application Catalog items, require the Touch Screen (Stylus) Catalog item.

Touch Screen (Stylus) Implementation Considerations
You can include Touch Screen (Stylus) functionality by adding the Touch Screen (Stylus) Catalog item to your OS design.
The following table shows the Sysgen variable that enables Touch Screen (Stylus) functionality.
| Sysgen variable | Description |
