addCallback in qtWidget

Hello @marcomusy,

I have been used addCallback in vedo2020 version and it worked. Recently, I upgraded my vedo verison to 2021.0.2, and I just found that the addCallback function no longer works for my pyqt application. I realized in the 2021 version, you have simplified the addCallback. The mousehighlight example works for me. I tried to adjust the related code according to the example, but always get the error as AttributeError: 'Plotter' object has no attribute '_timer_event_id'

The related code is something like

class Qt_App(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(Qt_App, self).__init__(parent)
        self.setupUi(self)
        
        self.vp = Plotter(qtWidget=self.vtkWidget)
        self.vp.addCallback('LeftButtonPressEvent', self.select)

    def select(self, evn):
        print('hello!', evn)

Could you help me figure it out? Many thanks!

Hi Bruce, sorry for the late reply, after: pip install -U git+https://github.com/marcomusy/vedo.git you should be able to run the example: https://github.com/marcomusy/vedo/blob/master/examples/other/qt_window1.py

Let me know if you encounter any problems
