Control state update method and device

Abstract

The embodiment of the present invention provides a control state update method and device. The method includes: the first-level control receives the update notification sent by the object; the level of the control is pre-divided; the first-level control is determined as the current-level control; Status update; if the current-level control has a next-level control, the current-level control sends an update notification to the next-level control; the next-level control that receives the update notification is determined as the current-level control; returns the current-level control in Steps to update the status according to the update notification when the self status is visible. In this way, it is possible to update the status when an update is required, reduce unnecessary interface refreshes, and improve the response speed of the interface. At the same time, by grading the controls, update notifications can be sent step by step, reducing the difficulty of debugging.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a control state updating method and device. Background technique [0002] The observer pattern is one of the most commonly used design patterns in software development. In the observer pattern, multiple observer events are registered on an object. When the object detects a change in the state of any of these observer events , will notify all observers registered on the object to update the state. For example, if a piece of text is selected in Word Processing System (WPS) office software, and the object detects that a selected event occurs, it will send a message to the corresponding font size, font color and other controls on the toolbar (that is, the observer of this event) Update notification, these controls update their states to the state corresponding to the font size and font color of the selected text according to the update notification. [0003] A common implementati...

Problems solved by technology

[0005] In the above-mentioned technical solution of the prior art, when a registered event occurs, no matter whether the event is dispatched synchronously or asynchronously, an update notification will be sent to all controls, but in fact not all controls are visible , for invisible controls, there is no need to update the state at this time. It can be seen that the existing technical solutions will cause many unnecessary control state updates, making the controls on the interface refresh frequently and the interface response speed is slow
