Abstract:
An electronic device and method are provided for rotating an object displayed at or by the device. The object may be an entire displayed region of a display screen, such as a window, frame, or other region or subregion, or a block element or other type of content component such as an image or map. A first input defining a reference point for the object is detected at a first user interface mechanism. After commencement of the detected first input, a second input at a second user interface mechanism, such as a touchscreen display, is detected. In response to the second input, a rotation transformation is applied to the object, the rotation transformation center being defined by the reference point, and the rotation transformation angle being defined by the second input. The object may be displayed by the touchscreen display, or by a display device external to the electronic device.
