A displaying method comprising: detecting a non-overlapping area (310, 410, 611, 612, 641, 751, 752) in a lower graphical user interface, GUI, object, wherein a lower GUI object refers to a GUI object displayed in a lower layer, the non-overlapping area is configured to include specific objects not to be covered by upper GUI objects (415, 511, 512), wherein upper GUI objects refer to GUI objects displayed in an upper layer, determining whether upper GUI objects (415, 511, 512) are displayed to overlap the non-overlapping area (310, 410, 611, 612, 641, 751, 752) at least in part; and changing, if upper GUI objects (511, 512) are displayed to overlap the non-overlapping area at least in part, a display configuration of the GUI objects, wherein: the changing of the display configuration comprises changing the display configuration of the overlapping upper GUI objects (511, 512) so that the overlapping upper GUI objects (511, 512) and the non-overlapping area are displayed not to overlap each other, characterized in that the changing of the display configuration of the overlapping upper objects (511, 512) comprises grouping the overlapping upper GUI objects (511, 512) into a folder according to properties information of each of the overlapping upper GUI objects and displaying the folder outside the non-overlapping area (310, 410, 611, 612, 641, 751, 752). detecting a non-overlapping area (310, 410, 611, 612, 641, 751, 752) in a lower graphical user interface, GUI, object, wherein a lower GUI object refers to a GUI object displayed in a lower layer, the non-overlapping area is configured to include specific objects not to be covered by upper GUI objects (415, 511, 512), wherein upper GUI objects refer to GUI objects displayed in an upper layer, determining whether upper GUI objects (415, 511, 512) are displayed to overlap the non-overlapping area (310, 410, 611, 612, 641, 751, 752) at least in part; and changing, if upper GUI objects (511, 512) are displayed to overlap the non-overlapping area at least in part, a display configuration of the GUI objects, wherein: the changing of the display configuration comprises changing the display configuration of the overlapping upper GUI objects (511, 512) so that the overlapping upper GUI objects (511, 512) and the non-overlapping area are displayed not to overlap each other, characterized in that the changing of the display configuration of the overlapping upper objects (511, 512) comprises grouping the overlapping upper GUI objects (511, 512) into a folder according to properties information of each of the overlapping upper GUI objects and displaying the folder outside the non-overlapping area (310, 410, 611, 612, 641, 751, 752). the changing of the display configuration comprises changing the display configuration of the overlapping upper GUI objects (511, 512) so that the overlapping upper GUI objects (511, 512) and the non-overlapping area are displayed not to overlap each other, characterized in that the changing of the display configuration of the overlapping upper objects (511, 512) comprises grouping the overlapping upper GUI objects (511, 512) into a folder according to properties information of each of the overlapping upper GUI objects and displaying the folder outside the non-overlapping area (310, 410, 611, 612, 641, 751, 752).
