双击QWidget(QWidget with doubleclick)

 我希望能够双击一个QPushbutton而不是一次点击。  
 我试过的：  
connect(pb, SIGNAL(doubleClicked()), this, SLOT(comBtnPressed()));
 
 错误说“QObject :: connect：没有这样的信号QPushButton :: doubleClicked（）”  
 我最初选择了QPushButton，但出于我的目的，如果可以进行双击事件，您可以建议更改为其他对象。 不一定是按钮。  
 谢谢Qt和C ++大师。 

I want to be able to double click a QPushbutton instead of a single click. 
What I tried:  
connect(pb, SIGNAL(doubleClicked()), this, SLOT(comBtnPressed()));
 
Error says "QObject::connect: No such signal QPushButton::doubleClicked()" 
I chose QPushButton initially, but for my purpose, you can suggest change to other object if it can make a doubleclick event. Not necessarily be a push button. 
Thank you Masters of Qt and C++.

 搞定了。 无论是否使用异步，正确的方法都有效，即在创建Jetty服务器连接器时设置输出缓冲区大小。  
HttpConfiguration httpConfig = new HttpConfiguration();
httpConfig.setOutputBufferSize(1024);
ServerConnector httpConnector = new ServerConnector(jettyServer,
        new HttpConnectionFactory(httpConfig));
 
 默认值为32768。  
 （注意：无需覆盖onResponseContent方法） 

Got it working. The proper approach works whether async is used or not, which is to set the output buffer size when creating the Jetty server connectors. 
HttpConfiguration httpConfig = new HttpConfiguration();
httpConfig.setOutputBufferSize(1024);
ServerConnector httpConnector = new ServerConnector(jettyServer,
        new HttpConnectionFactory(httpConfig));
 
The default is 32768. 
(Note: no need to override the onResponseContent method)
