List control and method for displaying big data items on basis of finite list items

Abstract

The invention provides a list control and method for displaying big data items on the basis of finite list items. The list control comprises sub-controls, a list item container, a control module and a scroll bar; the sub-controls are connected with a data storage module and each used for displaying single data information in one service logical data, the list item container comprises a set of the sub-controls and is used for determining the number and positions of the sub-controls needing to be displayed according to a data structure model of the service logical data, the control module is connected with the list item container and used for initializing a finite number of list items and controlling the number, positions or / and content of the displayed list items, and the scroll bar is connected with the control module and controls the finite number of list items to update the display positions or display content of the list items themselves in a rolling mode through the control module. According to the list control and method for displaying the big data items on the basis of the finite list items, a large number of list items do not need to be distributed, the memory space for list items is greatly reduced, the display capacity of the list control is greatly increased, and the hardware cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of computers and relates to a list display control, in particular to a list control and a method for displaying large data items based on limited list items. Background technique [0002] With the continuous and rapid development of science and technology, a large amount of related data is continuously aggregated, and the amount of data is getting larger and larger; the analysis of big data and detailed data show that the list control has played an increasingly important role, and at the same time, the performance of the list control And capacity has also had higher and higher requirements. [0003] The existing list control adopts the method of creating a new list item control every time a new piece of data is added, which reduces the efficiency of initializing large data of the list control. Every time a new list item control is created, even the list item control itself needs to consume system memory, co...
