Touch Screen (Stylus) Overview (Windows CE 5.0)

Send Feedback

Touch Screen (Stylus) functionality in Microsoft® 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.
