QT5 QWebView linker errors

qt-creator linker-errors qtwebkit qwebview qt5
Bobdabear picture Bobdabear · Jan 28, 2013 · Viewed 13.5k times · Source

Right now I'm just trying to get 'www.google.com' to load in a webview when a button is pressed. After I added the webview in the designer the linker starts going crazy. I'm using QT Creater 2.6.1 with QT5 on Windows 7. I added the QT += 'webkit stuff' to the .pro file. I've tried cleaning and rebuilding, still get linker errors.

for some odd reason adding "#include <QWebView>" in any file produces a file not found error: "C:\Users\Scott\Desktop\eCookBook\eCookBook2\cookbook.cpp:3: error: C1083: Cannot open include file: 'QWebView': No such file or directory"

cookbook.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

cookbook.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();

}

First try "Run qmake" (from the "Build" menu in Creator) to regenerate the make files and then re-build. Basically you need "Run qmake" after every modification in the .pro file.
