QGIS and PYQT5: Getting QgsAttributeForm.modeChanged signal

Question

I wonder how I can catch the signal, that attributes in a form are editable?

E.G. I open a form to see the values of the attributes of my geodata. Then I click on the "pencil" in QGIS (to make data editable). And right now a message should occure.

I tried:

def test(): qgis.utils.iface.messageBar().pushMessage("Status: ", u"Status: ")

    myDialog.modeChanged.connect(test)

...but that`s obviously not the correct way. Could anybody help?

I found a solution now. Via the layerObject it`s possible to get the EditingStatus:

   def testAusgabe(): qgis.utils.iface.messageBar().pushMessage("Statusx: ", u"Statusy: ")

    MyLayer.editCommandStarted.connect(testAusgabe)
    MyLayer.editingStarted.connect(testAusgabe)
