Hello,
I'm using a matplotlib plot embedded into a PyQt5 GUI.
After some modification the figure toolbar became grayed (visible but not
active) and no action is feasible anymore on the plot during running.
In the previous program versions it works, incidentally I guess since the
modifications I've made are only on the computational parts of the code.
Is there a way to control the activation of these interactive settings (I
really need to zoom and rotate 3d graph while running.).
I've already tried with setfocus command but no joy (I don't relay
understand how the focus is managed .)
Any help is welcome.
Thank you in advance and best regards.
Maurizio

from PyQt5.QtWidgets import *

from matplotlib.figure import Figure
class MplWidget(QWidget):
def __init__(self, parent = None):
QWidget.__init__(self, parent)
#self.figure = Figure()
self.canvas = FigureCanvas(Figure(constrained_layout=True))
self.toolbar = NavigationToolbar(self.canvas, self)
vertical_layout = QVBoxLayout()
vertical_layout.addWidget(self.toolbar)
vertical_layout.addWidget(self.canvas)
self.canvas.axesMain = self.canvas.figure.add_subplot(111)
self.setLayout(vertical_layout)
