Abstract

An electronic device and a method are adapted to identify window control commands in a multi-window system. The electronic device displays multiple windows each respectively having a title bar on a touch interface. The electronic device executes the method to identify a window control command according to a touch gesture from a movement of a touch point detected on the title bar of one of the windows. The user can easily touch the title bar to operate a certain window.
