Access qml object that was defined in python and dynamically (?) used in a repeater

SietseAchterop

Hello List,

EDIT: made the question a bit clearer I hope.
I have a python class that is registered and instantiated in qml.

qmlRegisterType(FigureCanvasQTAggToolbar, "Backend", 1, 0, "FigureToolbar")

In qml I give the instantiation of FigureToolbar the object name "pieces".
I want to access that object using a python class FormPieces and connect the two as follows:

  mainPieces = FormPieces()  
  engine.load( 'main.qml'))  
  win = engine.rootObjects()[0]  
  mainPieces.figure = win.findChild(QObject, "pieces").getFigure()

I now can use the FigureToolbar from mainPieces. This works fine.

But now I have a number of these FigureToolbars in a Repeater, the number can vary.
The Repeater is as follows:

	Repeater {
	    model: draw_mpl.nmbrRowers
	    delegate: RowerProfile {
		rindex : index
	    }
	}

In Python I do the apropriate number of times::

rowerPlots[i] = RowerForm(i)

In RowerProfile item, in the Figuretoolbar, I do the following in the hope the object is available when completed.:

        objectName = 'viewrower' + theindex;
        Component.onCompleted: draw_mpl.rowerprofile(objectname)

Then in python in rowerprofile(n) I do:

   rowerPlots[i].figure = win.findChild(QObject, n).getFigure()

Rowerprofile is called the correct number of times, the different objectNames are coming across , but I get the following error:

AttributeError: 'NoneType' object has no attribute 'findChild'

I don't understand this, the object is completed, it has it's correct objectname, but it can't be found?

What I also did try was to make getFigure a slot of the FigureToolbar and then:

 Component.onCompleted: draw_mpl.rowerprofile(getFigure())

But then I get undefined in python. Also putting the result in a list did not work.

So, how can I, in Python or C++, get access to a method in an object in qml inside a repeater object when it is dynamically created?

Thanks in advance, Sietse
