[SOLVED]addToJavaScriptWindowObject dosn´t work in Html5ApplicationViewer but in QWebView

Kleisophabo

Hi,

i have a problem with addToJavaScriptWindowObject.

I started a project as HTML5 Application and then i tried to connect Javascript with Qt like this:
@#include <QApplication>
#include "html5applicationviewer.h"
#include "javascriptcontroller.h"
#include <QGraphicsWebView>
#include <QWebFrame>
#include <QtWebKit>

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

Html5ApplicationViewer viewer;
viewer.setOrientation(Html5ApplicationViewer::ScreenOrientationAuto);
viewer.showExpanded();
viewer.loadFile&#40;QLatin1String("html/index.html"&#41;&#41;;
viewer.webView()->page()->mainFrame()->addToJavaScriptWindowObject("Qt", new JavaScriptController);

}@

but it dosnt work. The JavaScript dosnt find the method returing the message:

Type Error: undefined is not a constructor(evaluating Qt.test)

But running the same Code in a Qt Application with a QWebView works

@#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QWebFrame>

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

DataBaseController *dbc = new DataBaseController;
dbc->setDataBase("Lop.db3");
ui->webView->page()->mainFrame()->addToJavaScriptWindowObject("Qt", new JavaScriptController);

}

MainWindow::~MainWindow()
{
delete ui;
}
@

Here is the JavaScriptController.h

@#ifndef JAVASCRIPTCONTROLLER_H
#define JAVASCRIPTCONTROLLER_H

#include <QObject>

class JavaScriptController : public QObject
{
Q_OBJECT
public:
explicit JavaScriptController(QObject *parent = 0);

signals:

public slots:

Q_INVOKABLE QString test();

// Q_INVOKABLE QString queryVehicleBrand(QString jsonString);

};

#endif // JAVASCRIPTCONTROLLER_H@

and the .cpp

@#include "javascriptcontroller.h"
#include <QMessageBox>

JavaScriptController::JavaScriptController(QObject *parent) :
QObject(parent)
{
}

}

QString JavaScriptController::test(){
QMessageBox msg;
msg.setText("WTF IT WORKS!?");
msg.exec();
}
@

and this is the snippet from JavaScript

@function qtQueryVehicleBrand(request) {
try{
Qt.test();
}catch(err){
alert(err)
}
return '{"status":"ERR","message":"HaHa"}';@

Does anyone see what i´m doing wrong in the HTML5 Application?

Well I solved this problem after a few sleepless nights by my own. I still don't know why it doesn't need the connect method in the QWebview but in the Html5ApplicationViewer. Anyway, all what count is that it works now^^

I had to add in my JavaScriptController

@JavaScriptController::JavaScriptController(QObject *parent, QWebFrame *_webFrame) :
QObject(parent)
{
webFrame = _webFrame;
QObject::connect(webFrame,SIGNAL(javaScriptWindowObjectCleared()), SLOT(addToJavaScript()));

}

void JavaScriptController::addToJavaScript() {
webFrame->addToJavaScriptWindowObject("MyQtJavaScriptController", this);
}@
