Qt混合式开发—网页调试

Qt混合式开发—网页调试

Qt混合式开发时有些问题需要在运行环境下才会出现，这时候就需要在app上调试网页，qt就提供了调试网页的方法，下面就是调出调试窗口的方法：
//调试界面的实现

#ifndef INSPECTOR_H
#define INSPECTOR_H

#include <QQuickItem>
#include <QDialog>
#include <QPushButton>
#include <QWebEngineView>
#include <QStackedLayout>

class Inspector : public QDialog
{
public:
    Inspector(QWebEnginePage *source,QWidget *parent = nullptr);
private:
    QWebEngineView* m_webView = nullptr;
protected:
     void closeEvent(QCloseEvent *event);
};

#endif // INSPECTOR_H

#include "inspector.h"

Inspector::Inspector(QWebEnginePage *source, QWidget *parent):QDialog(parent)
{
    resize(1500,800);
   m_webView = new QWebEngineView(this);
   source->setDevToolsPage(m_webView->page());
   source->triggerAction(QWebEnginePage::InspectElement);
   QStackedLayout* layout = new QStackedLayout(this);
   this->setLayout(layout);
   layout->addWidget(m_webView);
   QDialog::show();
}

void Inspector::closeEvent(QCloseEvent *)
{
    this->accept();
    delete m_webView;
}

实现网页右击弹出菜单选项，点击调试按钮弹出调试窗口

class QWebview : public QWebEngineView
{
    Q_OBJECT
public:
    QWebview(QString sUrl,QWidget *parent = nullptr);
    ~QWebview() override;

protected:
    void contextMenuEvent(QContextMenuEvent *event) override;
};

void QWebview::contextMenuEvent(QContextMenuEvent *event)
{
    QMenu *menu = page()->createStandardContextMenu();

    const QList<QAction *> actions = menu->actions();
    auto inspectElement = std::find(actions.cbegin(), actions.cend(), page()->action(QWebEnginePage::InspectElement));
    if (inspectElement == actions.cend()) {
        auto viewSource = std::find(actions.cbegin(), actions.cend(), page()->action(QWebEnginePage::ViewSource));
        if (viewSource == actions.cend())
            menu->addSeparator();

        QAction *action = new QAction(menu);
        action->setText("Open inspector in new window");
        QAction *before(inspectElement == actions.cend() ? nullptr : *inspectElement);
        menu->insertAction(before, action);
        connect(action, &QAction::triggered,this,[this](){new Inspector(page());});
    } else {
        (*inspectElement)->setDisabled(true);
    }
    menu->popup(event->globalPos());
