篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了CTK-使用ctk框架完成日志打印界面插件相关的知识,希望对你有一定的参考价值。

 一、项目介绍

1、主要为了在此小型测试项目中用到几乎所有ctk的常用知识:

插件间通信、服务工厂、服务追踪、事件监听、框架封装

2、项目共包含3个插件
日志插件:用于模拟将接收的信息存储到日志中【这里只做简单的打印】,并且能够接收信息【主要来自界面插件】

打印插件:根据不同的插件返回提供不同打印服务

界面插件:封装一个界面插件,能够向框架发送信息【类方式和信号槽方式】

3、架构图

 二、打印插件编写

1、工程结构

技术图片

 

2、接口类

absprintserver.h

#ifndef ABSPRINTSERVER_H
#define ABSPRINTSERVER_H

#include <QObject>
class AbsPrintServer
{
public:
    virtual ~AbsPrintServer(){}
    virtual void print(QString) = 0;
};
Q_DECLARE_INTERFACE(AbsPrintServer,"judesmorning.zxy.AbsPrintServer")

#endif // ABSPRINTSERVER_H

3、实现类1,为日志插件提供服务

printserver.h

#ifndef PRINTSERVER_H
#define PRINTSERVER_H
#include <QObject>
#include "absprintserver.h"

class PrintServer : public QObject, public AbsPrintServer
{
    Q_OBJECT
    Q_INTERFACES(AbsPrintServer)
public:
    PrintServer();
    void print(QString info) override;
};

#endif // PRINTSERVER_H

printserver.cpp

#include "printserver.h"
#include <QDebug>
PrintServer::PrintServer()
{

}

void PrintServer::print(QString info)
{
    qDebug()<<info+"----print plugin for FirstPlugin";
}

4、实现类2,为界面插件提供服务

printservert.h

#ifndef PRINTSERVERT_H
#define PRINTSERVERT_H


#include <QObject>
#include "absprintserver.h"

class PrintServerT : public QObject, public AbsPrintServer
{
    Q_OBJECT
    Q_INTERFACES(AbsPrintServer)
public:
    PrintServerT();
    void print(QString info) override;
};

#endif // PRINTSERVERT_H

printservert.cpp

#include "printservert.h"
#include <QDebug>
#include <QTime>
PrintServerT::PrintServerT()
{

}
void PrintServerT::print(QString info)
{
    qDebug()<<QTime::currentTime().toString("HH:mm:ss    ")<<info+"----print plugin for CreateCtkUiPlugin";
}

5、实现类3,为其他插件提供服务

 printserverd.h

#ifndef PRINTSERVERD_H
#define PRINTSERVERD_H
#include <QObject>
#include "absprintserver.h"

class PrintServerD : public QObject, public AbsPrintServer
{
    Q_OBJECT
    Q_INTERFACES(AbsPrintServer)
public:
    PrintServerD();
    void print(QString info) override;
};

#endif // PRINTSERVERD_H

printserverd.cpp

#include "printserverd.h"
#include <QDebug>
PrintServerD::PrintServerD()
{

}

void PrintServerD::print(QString info)
{
    qDebug()<<info+"....----print plugin for unknown plugin";;
}

6、单独为接口编写服务追踪类

tracker.h

#ifndef TRACKER_H
#define TRACKER_H

#include "ctkServiceTracker.h"
#include "absprintserver.h"
#include "ctkPluginContext.h"
class Tracker : public ctkServiceTracker<AbsPrintServer*>
{
public:
    Tracker(ctkPluginContext* context);
protected:
    AbsPrintServer* addingService(const ctkServiceReference& reference) override;
    void modifiedService(const ctkServiceReference& reference, AbsPrintServer* service) override;
    void removedService(const ctkServiceReference& reference, AbsPrintServer* service) override;
private:
    ctkPluginContext* context;
};

#endif // TRACKER_H

tracker.cpp

#include "tracker.h"


Tracker::Tracker(ctkPluginContext *context)
    : ctkServiceTracker<AbsPrintServer*> (context)
{

}

AbsPrintServer *Tracker::addingService(const ctkServiceReference &reference)
{
    AbsPrintServer* service = static_cast<AbsPrintServer*>(ctkServiceTracker::addingService(reference));
    return service;
}

void Tracker::modifiedService(const ctkServiceReference &reference, AbsPrintServer* service)
{
    ctkServiceTracker::modifiedService(reference,service);
}

void Tracker::removedService(const ctkServiceReference &reference, AbsPrintServer* service)
{
    ctkServiceTracker::removedService(reference,service);
}

注意这个服务追踪类是在日志插件里使用的,只是从职责上来讲这个类应该编写此插件的人来编写,降低耦合性

 

三、日志插件编写

1、工程结构

2、接口类

abslogservice.h

#ifndef ABSLOGSERVICE_H
#define ABSLOGSERVICE_H

#include <QObject>
class AbsLogService{
public:
    virtual ~AbsLogService(){}
    virtual void log(QString info) = 0;
};
Q_DECLARE_INTERFACE(AbsLogService,"judesmorning.zxy.AbsLogService")


#endif // ABSLOGSERVICE_H

3、实现类

#ifndef LOGSERVICE_H
#define LOGSERVICE_H
#include <QObject>
#include "includes.h"
#include "abslogservice.h"
#include "service/event/ctkEventHandler.h"

    :context(context)
{

    p_tracker.reset(new Tracker(context));
    p_tracker->open();

    Q_PLUGIN_METADATA(IID "LogPlugin")

public:
    FirstPluginActivator();
    void start(ctkPluginContext *context);
    void stop(ctkPluginContext *context);

#ifndef INCLUDES_H
#define INCLUDES_H

#include <QString>
/*公共定义*/

//日志相关
enum _Log_Level{
    LOG_LEVEL_DEBUG = 0,
    LOG_LEVEL_INFO,

    LOG_LEVEL_ERROR,
    LOG_LEVEL_CRITICAL
};//日志等级
typedef struct _LogInfo {
    _Log_Level level;   //日志类型
    QString pluginName; //插件名称
    QString info;       //日志信息
} LogInfo;//日志详情


#endif // INCLUDES_H

    if (ref) {
        ctkEventAdmin* eventAdmin = context->getService<ctkEventAdmin>(ref);
        ctkDictionary props;
        props["level"] = logInfo.level;
        props["pluginName"] = logInfo.pluginName;
        props["info"] = logInfo.info;
        ctkEvent event("kdhy/yunwei/generalevent/log", props);
        qDebug() << "ui plugin send " << logInfo.info;
        eventAdmin->sendEvent(event);//sendEvent:同步 postEvent:异步
    }

    ~Myui();

signals:
void publishLogEventSignal(LogInfo);
void publishLogSignal(ctkDictionary info);

private slots:
    void on_pushButton_clicked();

    void on_pushButton_2_clicked();

private:
    Ui::Myui *ui;
};

#endif // MYUI_H

myui.cpp

#include "myui.h"
#include "ui_myui.h"

Myui::Myui(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Myui)
{
    ui->setupUi(this);
}

Myui::~Myui()
{
    delete ui;
}

//发送event事件
void Myui::on_pushButton_clicked()
{
    qDebug()<<"ui plugin send a event";
    LogInfo logInfo;
    logInfo.level = LOG_LEVEL_INFO;
    logInfo.pluginName = "CreateCtkUiPlugin";
    logInfo.info = "Event info:"+ui->textEdit->toPlainText();
    emit publishLogEventSignal(logInfo);
}
//发送信号事件
void Myui::on_pushButton_2_clicked()
{
    ctkDictionary props;
    props["level"] = LOG_LEVEL_INFO;;
    props["pluginName"] = "CreateCtkUiPlugin";
    props["info"] = "Signal info:"+ui->textEdit->toPlainText();
    emit publishLogSignal(props);
}

myui.ui

5、激活类

uiactivator.h

#ifndef UIACTIVATOR_H
#define UIACTIVATOR_H

#include <QObject>
#include "ctkPluginActivator.h"
#include "ctkPluginContext.h"
#include "uiservice.h"

    m_ui.reset(new UiService(context));
}

void UiActivator::stop(ctkPluginContext *context)
{
    Q_UNUSED(context)
}

6、插件间通信的结构体定义

includes.h

#ifndef INCLUDES_H
#define INCLUDES_H

#include <QString>
/*公共定义*/

//日志相关
enum _Log_Level{
    LOG_LEVEL_DEBUG = 0,
    LOG_LEVEL_INFO,
    LOG_LEVEL_WARNING,
    LOG_LEVEL_ERROR,
    LOG_LEVEL_CRITICAL
};//日志等级
typedef struct _LogInfo {
    _Log_Level level;   //日志类型
    QString pluginName; //插件名称
    QString info;       //日志信息
} LogInfo;//日志详情


#endif // INCLUDES_H

 

五、使用

1、新建控制台工程
