Operating System Signals to Applications Responsive to Double-Tapping

摘要

A mobile device can execute an operating system that presents icons on a touchscreen. The mobile device can detect a single-tap or a double-tap made by the user relative to an icon. In response to a single-tap relative to an icon, the operating system can send a first type of signal to an application. In response to a double-tap relative to the icon, the operating system can send a second type of signal to the application. The application can react to the receipt of the first type of signal in a manner that is different from the manner in which the application reacts to the receipt of the second type of signal. In response to first type of signal, the application can present an item list. In response to the second type of signal, the application can enable new item creation.
