Revision 1.0 Guru of the Week Terms : Kingofark and guru of the week Author: Kingofark Difficulty: 0/10 (This article is the preface of GOTW's translator Kingofark--well, even the preface--to express his personal feelings, and to introduce Gotw and his author.) ） [ about Herb Sutter] Herb Sutter is a renowned expert in C + + software development and is regularly invited to speak at talks around the worl

A deep understanding of the specific use of slot and slot-scope in vue, vueslot-scopePreface The slot documentation in vue is short, and the language is concise. In addition, it differs in the usage frequency and sequence of common options such as methods, data, and computed, this may make it easy for the developer who first came into contact with the

Sometimes our vue component needs to copy the content transmitted by the user. For example, the carousel components in our project need to use the replicated slots to achieve the cyclic scrolling effect. The user pays attention to the static effect of the carousel content, and the component is responsible for rolling it up. Component: lt; Div class = "horse-lamp" gt; lt; Div class = "lamp" gt; lt; slot name = "lamps" gt; lt;/

The signal slot technology has been around for a long time. I have long heard of a large number of applications in QT and have never studied it together. I recently used libjingle and read related articles and code. It uses the template technology to decouple the message producer -- trigger signal object and the consumer -- receiver signal object (slot), which simplifies the code. Similar Technologies commo

The parent component obtains the data of the Child component. * Child components send their own data to the parent * Vm. $ emit (event name, data ); * V-on :@ Example usage: When the send button is clicked, "111" is changed to "I am the da

Data partitioningRedis clusters store data on multiple nodes, that is, different partitions are stored on different nodes, and each node can store multiple partitions. Each partition is also referred to as a "hash slot" in Redis, with a total of 16,384 partitions planned in the Redis cluster. For example: when there are 3 nodes in a cluster, Node A will contain 0-5460 partitions, Node B will contain 5461-10922 partitions, and node C will contain 10923

Redis3.0 cluster CRC16 algorithm PHP client Implementation method (PHP obtains the Redis partition slot of Redis data in the redis3.0 cluster and obtains the Redis server address of the partition based on the partition slot)

Sometimes, when writing connect, you may hesitate to ask the question-do not need to be a virtual function in my slot function. I will ask myself this question every time I write connect, because if you don't go into MOC, you won't find too many problems. For example, there is a demo. #include In short, many people will habitually establish the connect mechanism when constructing functions of the base class, but at this time, because one of Objectiv

1. See if you have q_object in your class declaration and inherit the public qmainwindow{ For example: Class Cplot:public qmainwindow{ q_object 2, you declare the function to add the declaration: Private Slots: void xxxx (); And you want to add the function above to the constructor, which is accessed directly by the constructor: Public: Cplot (Qwidget *parent = 0); Private slots: void OpenFile (); void Segmentobj (); void Capture (); void Drawrays ()

Let's look at the internal implementation of sigslot. H. Take the relatively simple signal1 as an example. It can have one parameter. One of the two template parameters is a parameter type, and the other is a multithreading policy. Focuses on its 1) connect the Connect Method to the target class and target method 2) emit method, corresponding method for sending trigger messages to the slot Template ... To be continued...

The Guru mythRyan BrushAnyone who have worked in software LONG enough have heard questions like this:I ' m getting exception XYZ. Know what's the problem is?Those asking the question rarely bother to include stack traces, error logs, or any context leading to the problem. They seem to think are operate on a dif-ferent plane, which solutions appear to your without analysis based on evidence. They think you is a guru.We expect such questions from those
