Abstract

The invention discloses an unfolding method for a multilevel menu, which comprises the following steps: while detecting a next-level menu unfolding instruction, acquiring the center and radius of the circle of a last-level menu and the center and radius of the circle of the next-level menu; acquiring a theoretical display area for the next-level menu according to the center and radius of the circle of the last-level menu and the center and radius of the circle of the next-level menu; acquiring an area which does not exceed the boundary of a display interface in the theoretical display area for the next-level menu; taking the area which does not exceed the boundary of the display interface as a practical display area for the next-level menu. The invention also discloses an unfolding device for the multilevel menu. According to the unfolding method and device for the multilevel menu, the menu display can flexibly adapt to different display interfaces.

Description

technical field [0001] The invention relates to the field of interface display, in particular to a method and device for expanding a multi-level menu. Background technique [0002] With the rise of mobile electronic devices, especially the rise of touch mobile electronic devices, more and more disc-shaped menus have appeared, and all menus are displayed around a central position, and a level is expanded around the central position. A level submenu, such as figure 1 shown. [0003] When the menu is expanded to form a menu, it will encounter the problem of insufficient expansion space, especially for display screens of different specifications, the expanded sub-menu may exceed the display range, resulting in the failure to display part of the menu. Contents of the invention [0004] The main purpose of the present invention is to provide a method and device for expanding a multi-level menu, aiming at allowing the multi-level menu to be flexibly expanded according to differ...
