Hello, sorry if this has been covered but I did try to search and could not find a solution.
I am trying to use QtQuick to build user interface and work with C++ model.
So far the model is as simple as this.
class Axis : public QObject
{
Q_OBJECT
Q_PROPERTY(QString name READ name NOTIFY nameChanged)
public:
// ...
QString name() const;
// ...
};
class ApplicationData : public QObject
{
Q_OBJECT
Q_PROPERTY(QList<QObject*> axes READ axes NOTIFY axesChanged)
public:
// ...
QList<QObject*> axes() const;
// ...
private:
QList<QObject*> _axes;
};
ApplicationData::ApplicationData(QObject *parent) :
QObject(parent)
{
_axes.append(new Axis("Axis 1", this));
_axes.append(new Axis("Axis 2", this));
_axes.append(new Axis("Axis 3", this));
_axes.append(new Axis("Axis 4", this));
_axes.append(new Axis("Axis 5", this));
}
Now I am publishing the model like this:
ApplicationData data;
engine.rootContext()->setContextProperty("appData", &data);
In QML I want to display my axes list like this:
ListView {
model: appData.axes
delegate: Text { text: name }
}
But it is not displaying. When I run the code under QtCreator, the following messages are printed.
file:///.../app/Setup.qml:23: ReferenceError: name is not defined
file:///.../app/Setup.qml:23: ReferenceError: name is not defined
The number of messages equals to the number of objects in the object list, so it must be iterating correct object.
However for some reason I does not seem to be able to access individual elements from the list.
Also the following would work perfectly and display correct string:
Text {
text: appData.axes[2].name
}
Also the ListView will display the list as expected, if I publish it like this:
// C++ code
engine.rootContext()->setContextProperty("axes", QVariant::fromValue(data.axes()));
// QML code
ListView {
model: axes
delegate: Text { text: name }
}
Could anybody suggest what am I missing or how I can workaround?
Thanks
