How can i use Model c++ class in cascade with 2 other repeater in .qml file
0
I have followed this tutorial : https://resources.qt.io/resources-by-content-type-videos-demos-tutorials/using-c-models-in-qml-tutorial
This was usefull to create my c++ class to manage my LightModel
Now I want to re-use this tutorial where I have a model inside 2 other repeaters in cascade. The issue is that my qml code instantiate LightModel objects inside repeaters so I don't have access to these instances from main.cpp
I used qmlRegisterType to give qml the ability to create several objects from my LightModel class.
main.cpp
int main(int argc, char *argv)
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QApplication app(argc, argv);
qmlRegisterType<Light>("Light",1,0,"Light");
qmlRegisterType<LightModel>("Light", 1,0,"LightModel");
qmlRegisterUncreatableType<Light>("Light", 1, 0, "LightList", QStringLiteral("LightList should not be created in QML"));
QQmlApplicationEngine engine;
MainWindow w;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
if (engine.rootObjects().isEmpty())
return -1;
w.show();
return app.exec();
}

stepSize: 1
onValueChanged: {
model.value = value
}

}
}
}
}
}
My LightModel class is implemented like ToDoModel in the tutorial exemple : https://github.com/mitchcurtis/todo-list-tutorial/tree/chapter-11
So the question is : how can I access from C++ the content of the LightModel objects because the 24x7 instances are created by .qml file.
Thanks a lot for your time

Hi there, welcome to Stack Overflow! I really appreciate the inclusion of code and background of your issue. What is slightly bugging me, is the question at the end.how can I access. Can you clarify here? Access what? Access how? Individual objects ofLightModel? I would love it if you could clarify this. Thanks!

The easiest solution (but maybe not the best) would be to register eachLightModelfrom the constructor to theLightList. But it really depends on why you want to access the Lights. From theidit seems you are trying to create some sort of shop-gallery?

Hi, I update the post to integrate my LightModel.h and Light.h The updates are working fine because i can log and see model.value changing, but I have no way to see it from main.cpp In other words : i would like to correlate the instances LightModel created 24x7 times and identify each one with both index of repeater1 and repeater2 (generated by "model :24 and model:7") At the end I would like to have for example an array or a vector like :LightModel mArray[24][7]which reference all the instances by index them.

I've found the solution to my problem : stop using repeaters with StackLayout.
My editable content is stored inside an array, set as context property inside my main.cpp and the view get the value corresponding to the current index
light.h
#ifndef LIGHT_H
#define LIGHT_H
#include <QObject>
class LightV2 : public QObject
{
Q_OBJECT
public:
explicit LightV2(QObject *parent = nullptr);
public slots:
Q_INVOKABLE int getArrayValue(int indexLamp, int indexLight, int indexField);
Q_INVOKABLE int getBornInf(int indexLamp, int indexLight, int indexField);
Q_INVOKABLE int getBornSup(int indexLamp, int indexLight, int indexField);
Q_INVOKABLE int getDecimal(int indexLamp, int indexLight, int indexField);
Q_INVOKABLE void setArrayValue(int indexLamp, int indexLight, int indexField, int value);
private:
QString mDescription;
int mValue;
int mArrayValue[24][7][6];
int mBornInf[24][7][6];
int mBornSup[24][7][6];
int mDecimal[24][7][6];
};
#endif // LIGHTV2_H
main.cpp
int main(int argc, char *argv)

qmlRegisterType<GeneralConf>("Light", 1,0, "GeneralConf");
QQmlApplicationEngine engine;
LightV2 lights;
MainWindow w;
engine.rootContext()->setContextProperty("lights", &lights);
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
if (engine.rootObjects().isEmpty())
return -1;
w.show();
return app.exec();
}
finally : solution in main.qml

I've found the solution to my problem : stop using repeaters with StackLayout.
My editable content is stored inside an array, set as context property inside my main.cpp and the view get the value corresponding to the current index

Hi there, welcome to Stack Overflow! I really appreciate the inclusion of code and background of your issue. What is slightly bugging me, is the question at the end.
how can I access. Can you clarify here? Access what? Access how? Individual objects ofLightModel? I would love it if you could clarify this. Thanks!– TrebuchetMS
Nov 14 '18 at 10:19
The easiest solution (but maybe not the best) would be to register each
LightModelfrom the constructor to theLightList. But it really depends on why you want to access the Lights. From theidit seems you are trying to create some sort of shop-gallery?– Amfasis
Nov 14 '18 at 10:35
Hi, thank you both for your answer, @TrebuchetMS I would like to have the reference on the created objects because I want to do backend stuff with it. For exemple, this qml file create 24x7 instance of LightModel class, the user modify theses instances with the HMI, but I don't manage to reach these instances from c++. I don't know if you understand what I mean ?
– C. Duval
Nov 14 '18 at 10:44
@Amfasis, this will take a lot of lines in c++ file and a huge amount of lines in .qml file to register instances one by one and keep trace of them that way I think...

Hi, I update the post to integrate my LightModel.h and Light.h The updates are working fine because i can log and see model.value changing, but I have no way to see it from main.cpp In other words : i would like to correlate the instances LightModel created 24x7 times and identify each one with both index of repeater1 and repeater2 (generated by "model :24 and model:7") At the end I would like to have for example an array or a vector like :
LightModel mArray[24][7]which reference all the instances by index them.– C. Duval
