问题描述
我尝试使用'pywinauto'软件包，它可以工作。但是当我关闭应用程序时，python会提示消息“ python has
停止工作”。我根据Vasily Ryabov的建议添加了sys.coinit_flags = 2，警告消失了。
from PyQt5.QtWidgets import QApplication,QWidget,QPushButton
import sys
import warnings
warnings.simplefilter("ignore",UserWarning)
sys.coinit_flags = 2
from pywinauto.application import Application
from pywinauto.keyboard import send_keys
class App(QWidget):
def __init__(self):
super(App,self).__init__()
self.title = 'PyQt5 button - pythonspot.com'
self.left = 10
self.top = 100
self.width = 320
self.height = 200
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()
def on_click(self):
print('PyQt5 button click')
def main():
app = QApplication(sys.argv)
app.setStyle('Fusion')
w = App()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
但是当我尝试使代码复杂时，如果我单击第一个组合框以选择值“ ar-prod”，则会再次提示警告消息。

self.splitter1 = QSplitter(Qt.Horizontal)
# Add ComboBox
self.cb1=QComboBox() #ar-dev or ar-prod
self.cb1.addItems(['ar-dev','ar-prod'])

self.table.setHorizontalScrollBarPolicy(Qt.ScrollBaralwaysOff) # close horizontal scroll bar
self.table.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)
self.table.verticalHeader().setSectionResizeMode(QHeaderView.Stretch)
self.hfont = QFont('Times New Roman',12)
self.hfont.setBold(True)
self.table.horizontalHeader().setFont(self.hfont)
style = "::section {""background-color: lightgray; }"
self.table.horizontalHeader().setStyleSheet(style)
self.table.horizontalHeader().setFixedHeight(50)
self.bottomleft_layout.addWidget(self.table)
self.GroupBox1.setLayout(self.bottomleft_layout)
# Add Autoexec
self.GroupBox2 = qgroupbox("")
self.bottomright_layout = QVBoxLayout()
self.textEdit = QTextEdit()
self.bottomright_layout.addWidget(self.textEdit)
self.GroupBox2.setLayout(self.bottomright_layout)
self.tabs = QTabWidget()
self.tabs.addTab(self.GroupBox1,'Hyperlinks to Sub Folders')
self.tabs.addTab(self.GroupBox2,'Autoexec')
self.splitter2.addWidget(self.tabs)
self.mainLayout.addWidget(self.splitter1)
self.mainLayout.addWidget(self.splitter2)
self.setLayout(self.mainLayout)
if __name__ == '__main__':
main()
这是警告消息。
如果我删除self.cb1.addItems(['ar-dev','ar-prod'])并且不填充第一个组合框，则不会发生错误。
解决方法
在导入pywinauto之前，您需要sys.coinit_flags = 2。就像这里显示的一样：https://github.com/pywinauto/py_inspect/blob/master/py_inspect.py
