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

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.

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

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.

Re: [SailfishDevel] QML C++ Integration not working in Sailfish
Hi,
you should set the context property after loading the QML source. Then it ought
to be available from QML.

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

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

You're right, sorry! I must have confused something. I shouldn't
answer mails while on train. :)
