Trying to render a website on my program..

[U7Development]

Hi !

I want to show a website inside a QHBoxLayout

reservas.pro
QT += core gui sql webengine

wprincipal.h

#ifndef WPRINCIPAL_H
#define WPRINCIPAL_H

#include <QMainWindow>

QT_BEGIN_NAMESPACE
namespace Ui { class wprincipal; }
QT_END_NAMESPACE

class QWebEngineView;


class wprincipal : public QMainWindow{
    Q_OBJECT
public:
    wprincipal(QWidget *parent = nullptr);
    ~wprincipal();

private:
    Ui::wprincipal *ui;
    QWebEngineView* web;

};
#endif // WPRINCIPAL_H

wprincipal.cpp

#include "wprincipal.h"
#include "ui_wprincipal.h"
#include <QtWebEngineWidgets/QtWebEngineWidgets>
#include <QUrl>

wprincipal::wprincipal(QWidget *parent) : QMainWindow(parent), ui(new Ui::wprincipal){
    ui->setupUi(this);

    web = new QWebEngineView;     //** got error
    ui->hlWeb->addWidget(web);
    web->page()->load(QUrl("http://www.google.com"));

**Got error:
undefined reference to `QWebEngineView::QWebEngineView(QWidget)'

Do I need to do something else?...
Thanks in advance.

@U7Development said in Trying to render a website on my program..:

QT += core gui sql webengine

As shown in the documentation (https://doc.qt.io/qt-5/qwebengineview.html) it needs to be

QT += core gui sql webenginewidgets

Thanks for answering...
When i include that module i receive the error that the module is unknown...

@U7Development Which Qt version did you install and how?

[U7Development]

@jsulm i have installed 5.14 on Debian
Selected then the following items before installing:
Qt creator
Gcc kit
Sources
Qt webEngine

[jsulm]

@U7Development Then your users could simply do the same.

@jsulm excuse me, i did not get that..

@U7Development I think my last reply was meant for another thread, sorry :-)
Did you install Web Engine? It is not installed by default when using online installer. Start Qt Maintenance Tool and select Web Engine.

[U7Development]

@jsulm oh ok..

Yes, webengine is checked before installing it...
Im going to make a Windows test ..

@jsulm as reference i followed this video and did the same (only the first topic of the video)

I have returned here to say that i have solved it...!!
Just looked into the built in examples a very basic but working example and works!

This is what i did (for someone else that want to make it work)

1. Installed QtWebEngine from installer

2. on the .pro file, add webenginewidgets:
   QT += core gui sql webenginewidgets (was my case)

3. on wprincipal.ui added a Widget type container to hold the website (i named it wdgtWeb)

4. added pointer of type QWebEngineView to window widget header (wprincipal.h) in my case :

class QWebEngineView (forwarding)
private:
QWebEngineView* minsal_web {nullptr};

5. #include <QWebEngineView> on wprincipal.cpp

6. add these lines in somewhere you initialize your program (or in the constructor):

minsal_web = new QWebEngineView;
minsal_web->setParent(ui->wdgtWeb);
minsal_web->setFixedSize(QSize(1021, 701));
minsal_web->setUrl(QUrl(QStringLiteral("https://www.minsal.cl")));
minsal_web->show();

Point Nº 2 is the same as @jsulm said, for some reason now is getting fine... still don't get why...
but for sure, the Point Nº 5 is different than i was writing, so that helped too.
