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_msgs2、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 pathlib/librviz_teleop_commanderclass namerviz_teleop_commander/TeleopPaneltyperviz_teleop_commander::TeleopPanelbase_class_typerviz::PaneldescriptionA panel widget allowing simple diff-drive style robot base control./description/classclass namerviz_teleop_commander/cmd_controltyperviz_teleop_commander::cmd_controlbase_class_typerviz::PaneldescriptionA 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
?xml version1.0?

// END_TUTORIAL6、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 QTranslatorint 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.hMainWindow::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
