串口列表Combobox的显示问题 about comtool HOT 5 CLOSED

是的呢，因为只会在检测到有串口的情况下才会更新Combobox，所以在拔最后一个串口后，就不会去更新Combobox了 def detectSerialPortProcess(self): while(1): portList = self.findSerialPort() if len(portList)>0: currText = self.serialPortCombobox.currentText() self.serialPortCombobox.clear() for i in portList: showStr = str(i[0])+" "+str(i[1]) self.serialPortCombobox.addItem(showStr) index = self.serialPortCombobox.findText(currText) if index>=0: self.serialPortCombobox.setCurrentIndex(index) else: self.serialPortCombobox.setCurrentIndex(0) break # else: # self.serialPortCombobox.clear() time.sleep(1) self.showSerialComboboxSignal.emit() self.isDetectSerialPort = False

好的，谢谢您的回复，打扰了。
