CBackendLibVNCServer::OnInit
virtual OnInitReturnValue OnInit() override
Definition BackendLibVNCServer.cpp:72
CBackendLibVNCServer::OnProcess
virtual int OnProcess() override
插件连接的具体操作处理。因为此插件是非Qt事件，所以在此函数中等待。

CBackend::sigInformation
void sigInformation(const QString &szInfo)
从后台线程中触发在主线程中显示信息，不阻塞后台线程
CBackend::sigStop
void sigStop()
需要通知用户停止时触发。仅由插件触发。 当从插件中需要停止时触发。例如：对端断开连接、重置连接或者连接出错。
CBackend::sigShowMessageBox
void sigShowMessageBox(const QString &szTitle, const QString &szMessage, const QMessageBox::Icon &icon=QMessageBox::Information)
从后台线程中触发在主线程中显示消息对话框(QMessageBox)，不阻塞后台线程
CBackend::sigError
void sigError(const int nError, const QString &szError=QString())
当有错误产生时触发
CBackend::sigRunning
void sigRunning()
当插件开始成功后触发。仅由插件触发
CBackend::slotTimeOut
virtual void slotTimeOut()
一个非 Qt 事件处理，它调用 OnProcess()，并根据其返回值开始新的定时器。 如果是不是一个非 Qt 事件循环（就是普通的循环处理）， 可以重载它，或者 OnInit() 返回值大于 0

CBackend::sigBlockShowWidget
void sigBlockShowWidget(const QString &className, int &nRet, void *pContext)
阻塞后台线程，并在前台线程中显示窗口。
CParameterNet::m_User
