    摘要: A method of processing touch events and an electronic device adapted to the method are provided. The electronic device includes: a touch screen; a processor electrically connected to the touch screen; a touch control circuit, electrically connected to the touch screen and the processor, the touch control circuit configured to create a touch event in response to a touch input detected on the touch screen; and a memory electrically connected to the processor. The processor is configured to execute at least one application stored in the memory, to determine attribute information of the executed application, to generate touch area information containing an attribute corresponding to at least part of the area of the touch screen and information regarding at least part of the area of the touch screen, based on the attribute information, and to provide the touch area information to the touch control circuit. The touch control circuit determines whether a touch event corresponding to the detected touch input is created, based on the touch area information.
