您好，这是必应。我可以帮您生成一段使用QT C++编写一个带有菜单和工具条的文本编辑器的代码，但是请注意，这只是我的创造性的输出，并不代表任何权威或专业的观点。如果您想要了解更多的相关知识，请自行搜索或咨询专家。以下是我的代码：

// 假设有一个名为TextEdit的类，继承自QMainWindow，作为主窗口 // 假设有一个名为ui的Ui::TextEdit对象，用于设置界面

#include <QMainWindow> #include <QTextEdit> #include <QMenuBar> #include <QToolBar> #include <QAction>

class TextEdit : public QMainWindow { Q_OBJECT

public: TextEdit(QWidget *parent = nullptr); ~TextEdit();

private slots: void newFile(); // 新建文件 void openFile(); // 打开文件 void saveFile(); // 保存文件 void cut(); // 剪切 void copy(); // 复制 void paste(); // 粘贴 void about(); // 关于

private: QTextEdit *textEdit; // 文本编辑器组件 QMenuBar *menuBar; // 菜单栏组件 QToolBar *toolBar; // 工具栏组件 QAction *newAction; // 新建动作 QAction *openAction; // 打开动作 QAction *saveAction; // 保存动作 QAction *cutAction; // 剪切动作 QAction *copyAction; // 复制动作 QAction *pasteAction; // 粘贴动作 QAction *aboutAction; // 关于动作

};

TextEdit::TextEdit(QWidget *parent) : QMainWindow(parent) { ui->setupUi(this);

textEdit = new QTextEdit(this); setCentralWidget(textEdit);

menuBar = new QMenuBar(this); setMenuBar(menuBar);

toolBar = new QToolBar(this); addToolBar(toolBar);

newAction = new QAction(QIcon(“:/icons/new.png”), tr(“&New”), this); newAction->setShortcut(QKeySequence::New); newAction->setStatusTip(tr(“Create a new file”)); connect(newAction, &QAction::triggered, this, &TextEdit::newFile);

openAction = new QAction(QIcon(“:/icons/open.png”), tr(“&Open”), this);

openAction = new QAction(QIcon(“:/icons/open.png”), tr(“&Open”), this); openAction->setShortcut(QKeySequence::Open); openAction->setStatusTip(tr(“Open an existing file”)); connect(openAction, &QAction::triggered, this, &TextEdit::openFile);

saveAction = new QAction(QIcon(“:/icons/save.png”), tr(“&Save”), this); saveAction->setShortcut(QKeySequence::Save); saveAction->setStatusTip(tr(“Save the current file”)); connect(saveAction, &QAction::triggered, this, &TextEdit::saveFile);

cutAction = new QAction(QIcon(“:/icons/cut.png”), tr(“Cu&t”), this); cutAction->setShortcut(QKeySequence::Cut); cutAction->setStatusTip(tr(“Cut the selected text”)); connect(cutAction, &QAction::triggered, textEdit, &QTextEdit::cut);

copyAction = new QAction(QIcon(“:/icons/copy.png”), tr(“&Copy”), this); copyAction->setShortcut(QKeySequence::Copy); copyAction->setStatusTip(tr(“Copy the selected text”)); connect(copyAction, &QAction::triggered, textEdit, &QTextEdit::copy);

pasteAction = new QAction(QIcon(“:/icons/paste.png”), tr(“&Paste”), this); pasteAction->setShortcut(QKeySequence::Paste); pasteAction->setStatusTip(tr(“Paste the clipboard text”)); connect(pasteAction, &QAction::triggered, textEdit, &QTextEdit::paste);

aboutAction = new QAction(QIcon(“:/icons/about.png”), tr(“&About”), this); aboutAction->setStatusTip(tr(“Show the about dialog”)); connect(aboutAction, &QAction::triggered, this, &TextEdit::about);

menuBar->addMenu(tr(“&File”))->addActions({newAction, openAction, saveAction}); menuBar->addMenu(tr(“&Edit”))->addActions({cutAction, copyAction, pasteAction}); menuBar->addMenu(tr(“&Help”))->addAction(aboutAction);

toolBar->addActions({newAction, openAction, saveAction}); toolBar->addSeparator(); toolBar->addActions({cutAction, copyAction, pasteAction}); toolBar->addSeparator(); toolBar->addAction(aboutAction);
