Embodiment Construction

[0012] The tree control in the present invention has two sub-functions of background service and front-end display, the background is responsible for providing node data for the front-end display, and the front-end is responsible for receiving and displaying node data from the background; each node of the tree control has an ID value, and this node ID serves as A unique identifier for a tree node.

[0013] The present invention is a kind of method for solving the limitation of the number of tree control nodes, specifically comprising the following steps:

[0014] Step 1. When the software interface is just displayed, the tree control only displays the root node. When the user clicks on the root node, obtain all the lower-level child node data from the system background in an asynchronous manner, load the child node data in batches, and then load the data to The child node data of the node is cached in the local array, and finally, according to the nodes currently in the visibl...

Abstract

The invention discloses a method for solving tree control node quantity restriction. Node data is asynchronously loaded in batches to improve a tree control node data loading success rate and reduce a series of faults caused by the data loading failure of the tree control node data; the node data of a visible region is dynamically loaded, the node data of an invisible region can be removed, so that consumption on the memory of an operating system, a CPU (Central Processing Unit) and the like by the tree control can be effectively lowered, the resource use ratio of the operating system is improved, and the problem that an interface is stuck and the like since the tree control excessively consumes the resources of the operating system is solved so as to fundamentally break through the node quantity restriction by the tree control.

Description

technical field [0001] The invention relates to a method for solving the limitation on the number of tree control nodes. Background technique [0002] In the design of computer software interface, tree control is often used to display some data with hierarchical relationship. The traditional tree control adopts synchronous loading, and loads all node data at one time for display. As the amount of system data gradually increases, when the number of nodes in a tree control reaches tens of thousands or more, the traditional tree control will encounter data that cannot be successfully loaded from the background, and too many data nodes will cause the interface to freeze or even crash the entire interface. And other issues. However, the bottleneck of the number of tree control nodes seriously restricts the development of software interface design. Contents of the invention [0003] The purpose of the present invention is to provide a method for solving the limitation of the ...
