Swing APIs are designed to be powerful, flexible, and easy to use. In particular, we want programmers to easily create new swing components, whether from scratch or by extending some of the components we provide. For this purpose, swing components are not required to support multi-threaded access. Instead, we send a request to the component and execute the request in a single thread. This article discusses threads and swing components. The purpose is not only to help you use the swing API in a

Note that all these functions are not placed in update. If update () is enabled, it is not called once every S. If the interface is painted in update (), it will be repeatedly drawn and unnecessary.

Introduction and review
Before studying the tree, table, and asynchronous model, I will first review swing's single-thread rule and check its meaning.
Swing's single-threaded rule means that a swing component can only be accessed by one thread at a certain time.This rule applies to gets and sets, and "one thread" usually refers to the event dispatching thread.
The single-thread rule is commensurate with the application of the UI component, because th

defaults to dispatching SQL events to 1 groups, typically the one for which the write operation occurs.6. Add rules to proxysql hostIn/etc/proxysql.cnf, add the following: mysql_query_rules:

{
rule_id=1
active=1
match_pattern="^SELECT .* FOR UPDATE$"
destination_hostgroup=1
apply=1
},
{
rule_id=2
active=1
match_pattern="^SELECT"
destination_hostgroup=2
apply
In Java, Swing is thread-insecure and is a single-threaded design. As a result, only the event dispatching thread can access the Swing component to be drawn on the screen. The event dispatching thread is the thread that calls callback methods such as paint and update. It is also the event processing method defined in the event listener interface. For example, the actionreceivmed method in the ActionListener
