Short description

Hello,

I'm facing an issue with pyqtgraph. When I want to open a graph from another window, my program crash with an NSRangeException.

Code to reproduce

I can reproduce this problem with this simple code :

from PySide6.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget, QPushButton
from pyqtgraph import PlotWidget
import sys

class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        central_widget = QWidget(self)
        self.setCentralWidget(central_widget)

        layout = QVBoxLayout(central_widget)

        button = QPushButton("Open Graph", self)
        button.clicked.connect(self.open_graph)

        self.plot_widget = None

        layout.addWidget(button)

    def open_graph(self):
        graph_window = GraphWindow(self)
        graph_window.show()


class GraphWindow(QWidget):
    def __init__(self, parent=None):
        super(GraphWindow, self).__init__(parent)

        layout = QVBoxLayout(self)

        plot_widget = PlotWidget(self)
        layout.addWidget(plot_widget)

        x = [1, 2, 3, 4, 5]
        y = [10, 20, 15, 25, 30]
        plot_widget.plot(x, y, pen='b')

if __name__ == "__main__":
    app = QApplication(sys.argv)
    main_window = MainWindow()
    main_window.show()
    sys.exit(app.exec_())

Expected behavior

This code is excepted to open the graph.

Real behavior

When I click on the button a throw call stack appears :

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndexedSubscript:]: index 0 beyond bounds for empty array'

Additional context

I saw that NSExcepetion are specific to mac. Also, the following method doesn't work for me : https://matplotlib.org/3.1.0/faq/osx_framework.html

The problem occure only when I try to open a graph from another window. For example, the following code works well on my mac :

from PySide6.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget, QPushButton
from pyqtgraph import PlotWidget
import sys


class GraphWindow(QWidget):
    def __init__(self, parent=None):
        super(GraphWindow, self).__init__(parent)

        layout = QVBoxLayout(self)

        plot_widget = PlotWidget(self)
        layout.addWidget(plot_widget)

        x = [1, 2, 3, 4, 5]
        y = [10, 20, 15, 25, 30]
        plot_widget.plot(x, y, pen='b')


if __name__ == "__main__":
    app = QApplication(sys.argv)
    main_window = GraphWindow()
    main_window.show()
    sys.exit(app.exec_())

It might be because of my conda install because I'm trying on a basic Python install with pip and everything is working fine.

When I do pip list :

Wonder if it's an issue with pyside6 6.6.0 and qt-main 6.6.1. Either way I don't think this is a PyQtGraph issue (although if you find a workaround that PyQtGraph can implement that is painless, I'd love to see it).

I encountered a similar issue in my application. I do not have a minimal reproducible example but the problem arise, as @jordanlv originally reported, when creating a new window that contains one or more pyqtgraph widgets.

Here is my stack trace:

I guess it is related to PySide6 6.6.x since I tried the same application with version 6.5 and 6.4 and both gave no problem at all.

I only had the possibility to test on an Apple Silicon machine, so I don't know if it is reproducible on other OS/architectures.

This might be the same as [QTBUG-120181] Crash on macOS underneath libqcocoa.dylib's _ZN20QCocoaSystemTrayIcon13emitActivatedEv - Qt Bug Tracker from what things sound like.

You know I'm slacking when maintainers of adjacent libraries come in here to help me out ❤️

Hehe, small world! Just happened to find this after someone asking about it in the PySide group chat.

Per that Qt issue report, and my independent testing over with OBS, I think this is fixed in Qt 6.6.2.
