CloudCompare：自定义插件功能（V2.6）

CloudCompare官方给出了虚拟功能QDummyPlugin，可对其进行修改完成自己的功能。

笔者以新建功能xj（单击出现弹出对话框）为例，进行功能编写。

     

1、修改源码

在源码的plugins目录下新建xj文件夹，新建或复制QDummyPlugin下的5个文件并修改。

（1）CMakeLists.txt

cmake_minimum_required(VERSION 2.8)

#REPLACE ALL 'DUMMY' OCCURENCES BY YOUR PLUGIN NAME
#AND ADAPT THE CODE BELOW TO YOUR OWN NEEDS!

option( INSTALL_xj_PLUGIN "Check to install xj plugin" ON )

if (INSTALL_xj_PLUGIN)

#CloudCompare 'DUMMY' plugin
project( xj )

#load necessary libraries (see qPCV for an example)
#add_subdirectory (LIB1)

#if the plugin is an 'OpenGL filter', uncomment the line below
#set( CC_OPENGL_FILTER ON BOOL)
include( ../CMakePluginTpl.cmake )

#set dependencies to necessary libraries (see qPCV for an example)
#target_link_libraries( ${PROJECT_NAME} LIB1 )
#include_directories( ${LIB1_INCLUDE_DIR} )

endif()

（2）xj.cpp

主要算法或功能在 doAction()中填写

#include "xj.h"

//Qt
#include <QtGui>
#include <QTextCodec>
#include <QTranslator>

xj::xj(QObject* parent/*=0*/)
	: QObject(parent)
	, m_action(0)
{
#pragma region 中文
	QTextCodec::setCodecForTr(QTextCodec::codecForName("system"));//#include <QTextCodec>
	QTextCodec::setCodecForCStrings(QTextCodec::codecForName("system"));
	QTextCodec::setCodecForLocale(QTextCodec::codecForName("system"));
	QTranslator translator(0);//#include <QTranslator>
	translator.load("qt_zh_CN.qm");
#pragma endregion
}

void xj::onNewSelection(const ccHObject::Container& selectedEntities)
{
	//if (m_action)
	//	m_action->setEnabled(!selectedEntities.empty());
}

void xj::getActions(QActionGroup& group)
{
	//default action (if it has not been already created, it's the moment to do it)
	if (!m_action)
	{
		//here we use the default plugin name, description and icon,
		//but each action can have its own!
		m_action = new QAction(getName(),this);
		m_action->setToolTip(getDescription());
		m_action->setIcon(getIcon());
		//connect appropriate signal
		connect(m_action, SIGNAL(triggered()), this, SLOT(doAction()));
	}

	group.addAction(m_action);
}

void xj::doAction()
{
	//m_app should have already been initialized by CC when plugin is loaded!
	//(--> pure internal check)
	assert(m_app);
	if (!m_app)
		return;

	/*** HERE STARTS THE ACTION ***/

	//put your code here
	//--> you may want to start by asking parameters (with a custom dialog, etc.)
	//核心算法或功能
        QMessageBox::warning(0,"dd","ddd");

	//This is how you can output messages
	m_app->dispToConsole("[xj] Hello world!",ccMainAppInterface::STD_CONSOLE_MESSAGE); //a standard message is displayed in the console
	m_app->dispToConsole("[xj] Warning: xj plugin shouldn't be used as is!",ccMainAppInterface::WRN_CONSOLE_MESSAGE); //a warning message is displayed in the console
	m_app->dispToConsole("xj plugin shouldn't be used as is!",ccMainAppInterface::ERR_CONSOLE_MESSAGE); //an error message is displayed in the console AND an error box will pop-up!

	/*** HERE ENDS THE ACTION ***/

}

QIcon xj::getIcon() const
{
	//open xj.qrc (text file), update the "prefix" and the
	//icon(s) filename(s). Then save it with the right name (yourPlugin.qrc).
	//(eventually, remove the original xj.qrc file!)
	return QIcon(":/CC/plugin/xj/bg.jpg");
}

（3）xj.h

#ifndef xj_PLUGIN_HEADER
#define xj_PLUGIN_HEADER

//qCC
#include "../ccStdPluginInterface.h"

//Qt
#include <QObject>
#include <QString>

class xj : public QObject, public ccStdPluginInterface
{
	Q_OBJECT
	Q_INTERFACES(ccStdPluginInterface)
#ifdef CC_QT5
	//replace xj by the plugin name (IID should be unique - let's hope your plugin name is unique ;)
	Q_PLUGIN_METADATA(IID "cccorp.cloudcompare.plugin.xj")
#endif

public:

	//! Default constructor
	explicit xj(QObject* parent = 0);

	//inherited from ccPluginInterface
	virtual QString getName() const { return "界面显示中文插件名称"; }
	virtual QString getDescription() const { return "xj (dddddddddddddddddddddddddddd)"; }
	virtual QIcon getIcon() const;

	//inherited from ccStdPluginInterface
	void onNewSelection(const ccHObject::Container& selectedEntities);
	virtual void getActions(QActionGroup& group);

protected slots:

	/*** ADD YOUR CUSTOM ACTIONS' SLOTS HERE ***/
	void doAction();

protected:
	QAction* m_action;
};

#endif

（4）xj.qrc

<RCC>
  <qresource prefix="/CC/plugin/xj" >
    <file>bg.jpg</file>
  </qresource>
</RCC>

（5）图片根据个人喜好修改，笔者改成了bg.jpg。嘻嘻

2、CMAKE

按照流程，选择“INSTALL_xj_PLUGIN”，编译即可。

3、生成

VS中可以看到xj这个项目，生成解决方案即可。将…\plugins\xj\Release\xj.dll复制到…\qCC\Release\plugins目录下。

4、结果
