在PyQT4 python如何在整个窗口中禁用鼠标右键

Question

如何使用python禁用在PyQT4上的整个窗口中单击鼠标右键？

有两个框架..

app = QApplication(sys.argv)

# create grid layout
grid = QGridLayout()
browser = QWebView()
url_input = UrlInput(browser)


# url_input at row 1 column 0 of our grid
grid.addWidget(url_input, 1, 0)
# browser frame at row 2 column 0 of our grid
grid.addWidget(browser, 2, 0)
browser.load(QUrl("https://..."))
# main app window
main_frame = QWidget()
main_frame.setLayout(grid)
main_frame.show()

# close app when user closes window
sys.exit(app.exec_())
