An electronic device which includes a widget management module, a processor, a source acquiring module, and a display. The widget management module adds a new window and new viewable symbols or representations (views) inside the new window. The processor counts a number of existing windows and a number of existing views in each of the existing windows, calculates a new window identification code for the new window according to the number of existing window and the number of existing views in each of the existing windows, and calculates a new view identification code for each of the new views according to the new window identification code. The source acquiring module acquires sources and data from the sources based on each of the new view identification code and associates the source information with new view corresponding to the new view identification code, leading to the display of the new views.
