Designing a GUI development toolkit includes creating a windows event class with a property of window predefined condition events and a property of window drag and drop events; creating a windows adapter class with two trigger methods; creating a windows class with a window listener method configured to cause the window to enter into an edit mode in response to detecting the property of window predefined condition events is triggered; and to obtain and save initial location, dragged-to location and the mapping relationship between thereof for each component in the window in response to detecting that the property of window drag and drop events is triggered; and creating a component class with an action listener method defined to cause components in a window to be dragged to other locations of the window in which the components are located in response to detecting that the window is under the edit mode.

A rotary mechanism includes an upper seat pan, a lower seat pan and an arc slideway mechanism. The upper and lower seat pans are connected at their sides and can rotate relative to each other. A middle inner slide rail of the arc slideway mechanism, which has a long through-hole in its center and is fixed to the lower seat pan, is positioned between an upper supporting plate and a lower supporting plate, both of which have a long aperture in their respective centers. Fixed parts run through the long through-hole and the long apertures, and fix an upper outer slide rail and a lower outer slide rail. A locking mechanism having portions fixed to the upper seat pan and the lower seat pan, respectively, is arranged to cooperate with the arc slideway mechanism to limit relative rotation of the upper and lower seat pans.
