Question

我在Maya中使用PySide2创建了一个带有QWebView的小部件，该小部件将google.com加载到其showEvent上。

作为独立工具，我可以在Maya之外毫无问题地运行它，但是在Maya内部，当我使用其load方法时，它将立即崩溃。这很奇怪，因为在Maya崩溃时，我确实看到google已成功加载到我的小部件中。

我正在Centos 7上使用Maya 2018 Extension4。有人可以确认这也在您的计算机上崩溃吗？

这是我正在运行的脚本，每次都会崩溃：

from PySide2 import QtWidgets
from PySide2 import QtWebKitWidgets


class BrowserTool(QtWidgets.QWidget):

    def __init__(self, parent=None):
        super(BrowserTool, self).__init__(parent)

        self.resize(800, 800)

        self.web_view = QtWebKitWidgets.QWebView(parent=self)

        self.main_layout = QtWidgets.QVBoxLayout()
        self.main_layout.addWidget(self.web_view)
        self.setLayout(self.main_layout)

    def showEvent(self, event):
        self.web_view.load("http://www.google.com")


tool = BrowserTool()
tool.show()

Maya从崩溃文件中弹出的内容是
