python - State of Rectangle changes only when Clicking PyQt5 QML -

i have new pyqt5 application. wanted add inside qmainwindow qquickwidget , set properties qml. do:

class mainwindow(qtwidgets.qmainwindow):     def __init__(self):         super(mainwindow,self).__init__()         self.setgeometry(100,100,800,600)          engine = pyqt5.qtqml.qqmlengine(self)         view = qtquickwidgets.qquickwidget(engine,self)         view.setsource(pyqt5.qtcore.qurl("files/newqml.qml")) 

into qml file create rectangle states should changed when mouse hovering button. when hovered - nothing going on. state changes when click on button , when click , leave button. me, please. how can make right?
full qml code:

import qtquick 2.3 import qtquick.controls 1.2 import qtquick.window 2.2 import qtquick.controls.styles 1.2  rectangle{   signal buttonpressedsignal   signal buttonreleasedsignal   id: topbutton   width:80   height: 40   color: 'white'   border {width: 2; color: '#4caf50'}   state: 'normal'   text {     id: buttontext     anchors.centerin: parent     text:'button'     font.pixelsize: 20     font.family: 'hallo sans'     color: 'black'   }   mousearea{     anchors.fill: topbutton     hoverenabled: true     onpressed: parent.buttonpressedsignal()     onreleased: parent.buttonreleasedsignal()     onentered: parent.state='notnormal'     onexited: parent.state = 'normal'   }   states:[     state{       name: 'normal';       propertychanges{target:buttontext;color:'black';easing.type:easing.inoutelastic}     },     state{       name:'notnormal';       propertychanges{target:buttontext;color:'white';easing.type:easing.inoutelastic}     }   ]   transitions:[   transition{     to: '*'     coloranimation{target:buttontext;duration:400}   }   ] } 

the problem have not added qquickwidget qmainwindow correctly, must use setcentralwidget or layouts place them. qml has error easing.type part of propertyanimation , not of propertychanges.

import sys pyqt5 import qtwidgets, qtqml, qtquickwidgets, qtcore   class mainwindow(qtwidgets.qmainwindow):     def __init__(self):         super(mainwindow,self).__init__()         self.setgeometry(100,100,800,600)          engine = qtqml.qqmlengine(self)         view = qtquickwidgets.qquickwidget(engine,self)         view.setsource(qtcore.qurl("files/newqml.qml"))         self.setcentralwidget(view)   if __name__ == '__main__':     app = qtwidgets.qapplication(sys.argv)     w = mainwindow()     w.show()     sys.exit(app.exec_()) 

.qml
