按钮上单击

Question

我有一个带有4个按钮的python GUI脚本，可以调用4个相关的外部脚本。在单击每个按钮时，将运行每个相关的外部脚本，并为每个脚本创建一个单独的csv文件，其中包含数据。问题是，当我按下GUI上的按钮时，似乎不止一次运行相应的脚本，从而在每个csv中生成双倍的数据。我不希望这样，我只希望脚本在单击时运行一次以生成一次数据。如何阻止脚本在按钮单击时多次调用？

Answer 1

我认为您并不了解如何进行连接 你做的是：
1.在调用retranslateUi时将第一个按钮连接到一个功能 2.单击按钮时调用的函数将下一个按钮连接到新功能
3.等...所有按钮

因此，如果您在第一个按钮中单击几次（让我们说canonicalAddressesButton），它会连接几次按钮callLogButton。所以多次调用函数select_call_data。

因此，要正确连接所有按钮，您必须在函数retranslateUi中连接它们ALL，然后在此之后声明您的4函数进行连接。

注意与python的身份。

所以你需要改变它：

    # Canonical Addresses Button click functionality to parse canonical address data
    self.canonicalAddressesButton.clicked.connect(self.select_canonical_data)

def select_canonical_data(self):
    os.system('CanonicalAddressesParser.py')

    # Call Logs Button click functionality to parse call log data
    self.callLogButton.clicked.connect(self.select_call_data)

def select_call_data(self):
    os.system('CallLogParser.py')

    # SMS Button click functionality to parse SMS data
    self.smsButton.clicked.connect(self.select_sms_data)

def select_sms_data(self):
    os.system('SmsParser.py')

    # Sim Card Button click functionality to parse sim card data
    self.simCardButton.clicked.connect(self.select_sim_data)

def select_sim_data(self):
    os.system('SimCardParser.py')

by：

    # Canonical Addresses Button click functionality to parse canonical address data
    self.canonicalAddressesButton.clicked.connect(self.select_canonical_data)
    # Sim Card Button click functionality to parse sim card data
    self.simCardButton.clicked.connect(self.select_sim_data)
    # Call Logs Button click functionality to parse call log data
    self.callLogButton.clicked.connect(self.select_call_data)
    # SMS Button click functionality to parse SMS data
    self.smsButton.clicked.connect(self.select_sms_data)

def select_canonical_data(self):
    os.system('CanonicalAddressesParser.py')

def select_call_data(self):
    os.system('CallLogParser.py')

def select_sms_data(self):
    os.system('SmsParser.py')

def select_sim_data(self):
    os.system('SimCardParser.py')
