一、增加rviz plugin插件
资料：http://admin.guyuehome.com/42336
https://blog.51cto.com/u_13625033/6126970
- 这部分代码只是将上面两个链接中的代码整合在了一起，整合在一起后可以更好的理解其中的关系
1、创建软件包
catkin_create_pkg rviz_teleop_commander roscpp rviz std_msgs
2、创建plugin_description.xml文件
- 最后只是生成了一个动态库so文件，一个库里可以有多个插件，所以只有一个library
<library path="lib/librviz_teleop_commander"><class name="rviz_teleop_commander/TeleopPanel"type="rviz_teleop_commander::TeleopPanel"base_class_type="rviz::Panel"><description>A panel widget allowing simple diff-drive style robot base control.</description></class><class name="rviz_teleop_commander/cmd_control"type="rviz_teleop_commander::cmd_control"base_class_type="rviz::Panel"><description>A panel widget allowing simple diff-drive style robot base control.</description></class>
</library>3、处理package.xml文件
- 这部分不需要改太多，只在最后增加一个export即可

PLUGINLIB_EXPORT_CLASS(rviz_teleop_commander::cmd_control,rviz::Panel )
// END_TUTORIAL
6、编译并使用
- 编译通过后，打开rviz即可调用插件
二、通过Qt可视化工具构建rviz插件
1、qt creator开发
- rviz插件的源代码的主要库是qt库，qt库的常见开发方式是使用qt creator，代码框架主要是主函数+定义ui界面的cpp文件和h文件。
- 主函数基本就是启动代码，不用修改。
#include "mainwindow.h"#include <QApplication>
#include <QLocale>
#include <QTranslator>int main(int argc, char *argv[])
{QApplication a(argc, argv);QTranslator translator;const QStringList uiLanguages = QLocale::system().uiLanguages();for (const QString &locale : uiLanguages) {const QString baseName = "qt_to_rviz_" + QLocale(locale).name();if (translator.load(":/i18n/" + baseName)) {a.installTranslator(&translator);break;}}MainWindow w;w.show();return a.exec();
}- 头文件中声明需要用到的组件
#ifndef MAINWINDOW_H
#define MAINWINDOW_H#include <QMainWindow>
#include <QLabel>
QT_BEGIN_NAMESPACE
namespace Ui { class MainWindow; }
QT_END_NAMESPACEclass MainWindow : public QMainWindow
{Q_OBJECTpublic:MainWindow(QWidget *parent = nullptr);~MainWindow();private:Ui::MainWindow *ui;
private:QLabel *lab; //这里声明了一个标签组建，记得要引入对应组建的头文件
};
#endif // MAINWINDOW_H- cpp文件主要在构造函数中定义和启动组建
#include "mainwindow.h"
#include "ui_mainwindow.h"MainWindow::MainWindow(QWidget *parent): QMainWindow(parent), ui(new Ui::MainWindow)
{this->lab = new QLabel("Hello, world!", this);ui->setupUi(this);
}MainWindow::~MainWindow()
{delete ui;
}
- 这是普通qt程序的开发和使用方法，这里只有qt实现的界面可视化代码，没有增加业务功能代码。只要把这部分代码和业务代码耦合在一起就可以实现效果了
2、qt designer
- 还有一种方法是使用qt designer，这种工具通过可视化界面设计ui界面并设置相关配置，最后通过uic工具生成h文件，h文件中会有qt功能的主要代码，在其基础之上修改即可。
- 在qt designer中设计ui界面，保存为ui文件
* 使用uic生成头文件，相关类可以从这个头文件中挑选和复用代码，不过还是有挺多要修改的
uic mainwindow.ui -o qwe.h
