有没有办法阻止QWindowsNativeFileDialog :: OnSelectionChange（Qurl ...）注销到命令行？

Question

我看到每次与PyQt5交互时，PyQt5中的文件对话框小部件都会向命令行注销QWindowsNativeFileDialogBase::onSelectionChange (QUrl...)消息。有办法阻止这种情况发生吗？

电流输出：

您可以看到，当我单击“ codetesting.py”时，该消息会在命令行中弹出。

注销示例：

QWindowsNativeFileDialogBase::onSelectionChange (QUrl("file:///C:/Users/user/Documents/WaferMapViewerProject/src/main/python/codetesting.py")) 1

可运行代码：

运行此代码时，会弹出一个窗口，中间有一个按钮。单击文件对话框将打开。

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QFileDialog
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot
class App(QWidget):

    def __init__(self):
        super().__init__()
        self.title = 'PyQt5 button - pythonspot.com'
        self.left = 50
        self.top = 50
        self.width = 320
        self.height = 200
        self.initUI()

    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)

        button = QPushButton('PyQt5 button', self)
        button.setToolTip('This is an example button')
        button.move(100, 70)
        button.clicked.connect(self.on_click)

        self.show()

    @pyqtSlot()
    def on_click(self):
        print('PyQt5 button click')
        fname = QFileDialog.getOpenFileName()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

您可以使用QLoggingCategory禁用日志记录：

from PyQt5.QtCore import QLoggingCategory

QLoggingCategory.setFilterRules('qt.qpa.dialogs.debug=false')

或

import os
# ...

if __name__ == '__main__':

    os.environ["QT_LOGGING_RULES"] = "*.debug=false"

    app = QApplication(sys.argv)

    # ...
