Can you provide a code example, and the exact error(s) that you get.

Yes, it helped thanks.

My problem now is different.

I have some private attributes in my C++ object.

When I call the first tiem I can modify the attributes, but in the  
second call the attributes dessapear.


Is there a way to solve this problem?

(The attributes a new C++ Object not declared as QObject)

You can use qmlRegisterType to pass the Info of the C++ class to QML
like this in the cpp:

#include "bloomfilters.h"

int main(int argc, char *argv[])
{
   // Get App and QML-View objects
   QScopedPointer app(SailfishApp::application(argc,
argv));
   QScopedPointer view(SailfishApp::createView());

   // Register Bloomfilter Class
   qmlRegisterType("harbour.myapp.Bloomfilter", 1, 0,
"Bloomfilter");

   // Prepare the QML
   view->setSource(SailfishApp::pathTo("qml/bloomfilter.qml"));
   view->show();

   // Run the app
   return app->exec();
}

Afterwards you can create a Bloomfilter-Object in QML:

Bloomfilter {
   id: bloom
}

and use the methods with

bloom.insertElement("myelement")

I hope this helps.

Re: [SailfishDevel] QML C++ Integration not working in Sailfish

Yes, if you read the documentation pragma library cannot access qml properties 
directly. So its a feature.

Hi sylvain,

This is not the case a renamed the variable so the have exactly the same name.

On the other hand, may be the problem is that I am calling it from .js file by 
the next code:

.pragma library
.import QtQuick 2.0 as QQ

var appState;

function getAppState() { return appState; }


function newAppState(page)
{
appState = page;
getAppState().k=1;
getAppState().m=2;

return appState;
}

// Funciones especificas

function createBloomFilter() {
console.log("Voy a llamar a generate filter")
bloomfiltersdata.generateFilterInvokable2()
console.log("Ya he llamado a generate filter")
}

And I call this from the qml by:


import QtQuick 2.0
import Sailfish.Silica 1.0
import "pages"

import "pages/content"
import "pages/content/logic.js" as Logic
import fi.helsinki.cs 1.0

ApplicationWindow

property var appState: Logic.newAppState(appWin);
property ApplicationWindow appWin: appWin
property Bloomfilters bloomfilters: bloomfilters

Two things:

  1. Call setContextProperty() right before before setSource(), so it's
already available when the QML content is loaded.
  2. Use lowercase for context property names ("bloomfilters" instead of
"Bloomfilters"). In some places, QML interprets IDs starting with an
upper case letter as a type name, and that won't work then, therefore
stick to lowercase.

I would add an
console.log("Before called")
and see whether the createBloomFilter() function is entered at all.

Re: [SailfishDevel] QML C++ Integration not working in Sailfish

[antonio . cano . gomez]

Hi Andrey,

The output is: ReferenceError: bloomfilterdata is not defined

I am calling it from a .js

Some idea about how can I  make that this is also defined there.

Thanks!

Re: [SailfishDevel] QML C++ Integration not working in Sailfish

[Mikko Leppänen]

Hi,

Try creating Bloomfilters class instance before declaring view, and store
app and view either to qscopedpointer or qsharedpointer.

Two things:

  1. Call setContextProperty() right before before setSource(), so
it's
already available when the QML content is loaded.
  2. Use lowercase for context property names ("bloomfilters"
instead of
"Bloomfilters"). In some places, QML interprets IDs starting with an
upper case letter as a type name, and that won't work then, therefore
stick to lowercase.

Hi Thomas,

I did both modification but the code does not work yet.

Here is the new code:

    QGuiApplication *app = SailfishApp::application(argc, argv);
    QQuickView *view = SailfishApp::createView();

    Bloomfilters  * bloomfilters = new Bloomfilters();
    view->rootContext()->setContextProperty("bloomfiltersdata", 
bloomfilters);
    view->setSource(SailfishApp::pathTo("qml/bloomfilter.qml"));
    view->showFullScreen();

    return app->exec();

Re: [SailfishDevel] QML C++ Integration not working in Sailfish

[antonio . cano . gomez]

Hi J-P,

It is not working as I try to call the method generateFilterInvokable2()

in the function:

function createBloomFilter() {
    getAppState().filterCharged = true;
    Bloomfilters.generateFilterInvokable2()
    console.log("Called")
}


And as result "Called" is never printed. So I guess that it crashes.

Re: [SailfishDevel] QML C++ Integration not working in Sailfish

[Sylvain B .]

No, I am able to invoke c++ methods from QML while having exposed them the 
exact same way.
The only difference would be that my constructor is a simple "Bloomfilters()".
So same question than J-P: what exactly isn't working?

Re: [SailfishDevel] QML C++ Integration not working in Sailfish

[christopher . lamb]

Hi Antonio

Here is a simplified example from one of my projects, showing a number  
of ways to expose C++ to QML.


I tend to use qmlRegister when exposing C++ objects with methods,  
and SetContextProperty when I want to expose simple stuff like global  
constants only.


I do things that way because it works for me ...

Zitat von "Andrey Kozhevnikov" :


???

contextProperty should be set BEFORE loading QML source.

Hi,

What does "this is not working" mean? In what way is it not working?

[Luciano Montanaro]

I think you need to add a qRegisterMetatype() to be able to invoke
methods from qml.

[SailfishDevel] QML C++ Integration not working in Sailfish

[antonio . cano . gomez]

Hi,

I am trying to do a simple Sailfish aplication that uses a c++ library.  I try 
to connect my qml code with the C++ code.

First I create QObject extended library:


#ifndef BLOOMFILTERS_H
#define BLOOMFILTERS_H


#include 
#include "svn/bloom-read-only/bloom_filter.hpp"

class Bloomfilters : public QObject
{
    Q_OBJECT


public:
    Q_INVOKABLE  void generateFilterInvokable2() const ;
    Q_INVOKABLE  void generateFilterInvokable(const QString &cadenaK, const 
QString &cadenaM) const ;


    explicit Bloomfilters(QObject *parent = 0);

    void generateFilter() ;

    Q_INVOKABLE void insertElement(const QString &cadena) ;

    Q_INVOKABLE bool checkElement(const QString &cadena) ;




signals:


public slots:

private:
    bloom_parameters _parameters ;
    bloom_filter _filter;
    bool _filter_charged;
    QString _k;
};

#endif // BLOOMFILTERS_H



An I try to connect this with my sailfish application with the code:

    QGuiApplication *app = SailfishApp::application(argc, argv);
    QQuickView *view = SailfishApp::createView();
    Bloomfilters  * bloomfilters = new Bloomfilters();
    view->rootContext()->setContextProperty("Bloomfilters", bloomfilters);
    view->setSource(SailfishApp::pathTo("qml/bloomfilter.qml"));
    view->showFullScreen();
    return app->exec();


But this is not working.

Someone have any idea about what am I doing wrong?
