qt 创建器 - QT5 QWebView 链接器错误



现在我只是想在按下按钮时让'www.google.com'加载到网络视图中。 在设计器中添加 Web 视图后，链接器开始变得疯狂。 我在Windows 7上使用QT Creater 2.6.1和QT5。 我将QT +='webkit的东西'添加到.pro文件中。 我尝试过清理和重建，但仍然遇到链接器错误。

出于某种奇怪的原因，在任何文件中添加" #include <QWebView>"都会产生找不到文件的错误："C：\Users\Scott\Desktop\eCookBook\eCookBook2\cookbook.cpp：3：错误：C1083：无法打开包含文件："QWebView"：没有这样的文件或目录"

食谱.h：

#ifndef COOKBOOK_H
#define COOKBOOK_H
#include <QMainWindow>
#include <QtWebKit/QWebElement>
#include <QtWebKit/QtWebKit>
#include <QtWebKitWidgets/QWebPage>
namespace Ui {
class cookBook;
}
class cookBook : public QMainWindow
{
    Q_OBJECT
public:
    explicit cookBook(QWidget *parent = 0);
    ~cookBook();
private slots:
    void on_pushButton_clicked();
    void on_textBrowser_anchorClicked(const QUrl &arg1);

private:
    Ui::cookBook *ui;
    //QWebPage page;
};
#endif // COOKBOOK_H

食谱.cpp

#include "cookbook.h"
#include "ui_cookbook.h"
//#include <QWebView>
//#include <QtWebKit/QtWebKit>
cookBook::cookBook(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::cookBook)
{
    ui->setupUi(this);
}
cookBook::~cookBook()
{
    delete ui;
}

void cookBook::on_pushButton_clicked()
{
    ui->listWidgetTest->insertItem(ui->listWidgetTest->count(), "TEST");
    const QUrl testsite = "www.google.com";
    ui->widget->load(testsite);
    ui->widget->show();
}

When executing step 'Make'

首先尝试"运行 qmake"（从 Creator 中的"构建"菜单中）重新生成 make 文件，然后重新构建。基本上，您需要在每次修改.pro文件后"运行qmake"。

  1. 在创建器中按 Ctrl+5。
  2. 取消选中"影子构建"。

  3. 将.pro文件行更改为：

    QT += core gui network webkit webkitwidgets

  4. 重新生成项目

修复了相同的错误。尝试在包含中添加 qwebview.h 的路径，例如：（将"QtWebKitWidgets"更改为您的）

#include <QtWebKitWidgets/QWebView.h>

而不仅仅是#include <QWebView.h>

尝试将其添加到使用 QWebView 的所有文件中。
