[SailfishDevel] Sailfish and BidData
Hi! I am interested in provide sailfish with some technology for big data. Someone knows is there is already some project going on? Best Regards and Thanks, A. Cano ___ SailfishOS.org Devel mailing list
Re: [SailfishDevel] QML C++ Integration not working in Sailfish
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
{
initialPage: Component { FirstPage { } }
cover: Qt.resolvedUrl(cover/CoverPage.qml)
id: appWin
property var appState: Logic.newAppState(appWin);
property ApplicationWindow appWin: appWin
property Bloomfilters bloomfilters: bloomfilters
property var k
property var m
property bool filterCharged: false
}
Someone seems something unusual in this code?
Best Regards and Thanks,
A. Cano

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!

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();

But it is not working yet.
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.
HTH :)

Re: [SailfishDevel] QML C++ Integration not working in Sailfish
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
QScopedPointerQGuiApplication app(SailfishApp::application(argc,
argv));
QScopedPointerQQuickView view(SailfishApp::createView());
// Register Bloomfilter Class
qmlRegisterTypeBloomfilter, 1(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
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.

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?

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

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 QObject
#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?
