Qt5 How display a QML file

chrisadams

You can either use qmlscene as described "here":http://doc-snapshot.qt-project.org/5.0/qtquick/qtquick-quickstart-basics.html#loading-and-displaying-the-qml-document or you can define your own C++ entrypoint with a QQuickView as described "here":http://doc-snapshot.qt-project.org/5.0/qtquick/qquickview.html

Cheers,
Chris.

Thank you very much for the links,
But I've a problem : This code displays a little and empty window.
@
#include <QtQuick/QtQuick>
#include <QGuiApplication>

int main (int argc, char *argv[])
{
QGuiApplication app(argc, argv);

QQuickView view(QUrl::fromLocalFile&#40;"app.qml"&#41;);
view.show();
return app.exec();

}@
The content of app.qml is :

import QtQuick 1.1
import QtWebKit 3.0

Rectangle {
width: 360
height: 360

WebView {
        id: webview
        x: 0
        y: 0
        url: "http://qt-project.org"
        width: parent.width
        height: parent.height
}
        TextInput {
            id: text_input1
            x: 32
            y: 29
            width: 278
            height: 20
            color: red
            text: qsTr("url")
            font.pixelSize: 12
            onTextChanged: {
                webview.url = text;
            }
        }

}
I think there is a problem. But I don't know where it is. (Maybe it's between the keyboard and the chair)

I've an other problem : what is the include's path for QWebView (in C++) because I've download Qt 5.0.0 yesterday and I'd like to use a project created with Qt 4.7 with Qt 5.0.0.
In the documentation, it was written this :
#include <QWebView>
(Like in Qt 4.7)
But it's not working with me.

Hi,

Can you checking this example:
@
import QtQuick 2.0
import QtWebKit 3.0

Rectangle {
width: 360
height: 360

TextInput {
    id: address
    anchors.top: parent.top
    width: parent.width
    height: 20

    selectByMouse: true
    text:"http://google.com"

    onAccepted: {
        console.log(address.text);
        container.url = address.text;
    }
}

WebView {
    id: container
    anchors.bottom: parent.bottom
    width: parent.width
    height: parent.height - address.height
}

}
@

It's works for Qt 5.0 and QML 2.0. For apply the new url you must pressed Enter key.

I hope this help you!

Thank you very much !
Now I know what was the problem : I used QtQuick 1.1. When I use QtQuick 2.0, it's working. But when I try to see app.qml into Qt Designer, there is a error : unsupported QtQuick version. That's why I used QtQuick 1.1...
And does anyone know what is the include's path of QWebView in Qt 5.0 ?
I have another question : is it true that the QtWebKit2 is just available with the QML ? It seems to me that this is what I read in the documentation...

I don’t use Designer in my projects. But I checked it and get this issue. Also I found this "link":http://www.qtcentre.org/threads/52503-Qt-Creator-2-6-1-on-OSX-10-8-2-and-QML.

But I do not known How to fix it :-(.

Maybe this is "answer":http://www.qtcentre.org/threads/52569-QtQuick-2-0-doesn-t-work-on-OSX-Mountain-Lion-10-8-2?p=235388#post235388.

Thank you !
I think Qt Designer is not ready to display QML files (maybe in a future release...).
It would be nice if you have answers for the two others question ! I continue my search, but I don't find anything...

What question do you mean?

bq. And does anyone know what is the include’s path of QWebView in Qt 5.0 ?

Thank very much for all your replies !

If you need use WebKit in C++ code you may use this:
@
#include <QtWebKit/QtWebKit> //For WebKit
#include <QtWebkitWidgets/QtWebKitWidgets> //For QWebView and others widgets for showing HTML
@

Also you must enabled two modules in your .pro file.
@
QT += webkit webkitwidgents

No, you may use QtWebKit in Widget-based applications. See my first answer.

Now, whan I cmpile the modified code, I have 624 errors like that : main.obj:-1: erreur : LNK2019: symbole externe non résolu "__declspec(dllimport) public: virtual __thiscall QApplication::~QApplication(void)" (_imp??1QApplication@@UAE@XZ) référencé dans la fonction _main in english, I would give it : main.obj:-1: error : LNK2019: unresolved extern symbol "__declspec(dllimport) public: virtual __thiscall QApplication::~QApplication(void)" (_imp??1QApplication@@UAE@XZ) referencedin the function _main
If you know what it is, please tell me the solution !
