类型错误：参数 1 具有意外的类型'QPushButton'

Question

我遇到了这个问题，我不知道为什么不能工作。我对python还很陌生，所以如果你能帮我，我将不胜感激

这是一个非常简单的GUI，第一个页面在点击按钮时打开另一个页面，在第二个页面上，我需要打开一个浏览窗口，并将路径作为字符串

这是主页

from PyQt5 import QtCore, QtGui, QtWidgets
from testGui import Ui_Test
class Ui_PragrammingGUI(object):
def open_test_window(self):
self.window = QtWidgets.QMainWindow()
self.ui = Ui_Test()
self.ui.setupUi(self.window)
self.ui.get_all_serials()
self.window.show()
def setupUi(self, PragrammingGUI):
PragrammingGUI.setObjectName("PragrammingGUI")
PragrammingGUI.resize(237, 177)
self.centralwidget = QtWidgets.QWidget(PragrammingGUI)
self.centralwidget.setObjectName("centralwidget")

self.test_2 = QtWidgets.QPushButton(self.centralwidget)
self.test_2.setGeometry(QtCore.QRect(60, 100, 121, 31))
self.test_2.setObjectName("test_2")
self.test_2.clicked.connect(self.open_test_window)
PragrammingGUI.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(PragrammingGUI)
self.menubar.setGeometry(QtCore.QRect(0, 0, 237, 20))
self.menubar.setObjectName("menubar")
PragrammingGUI.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(PragrammingGUI)
self.statusbar.setObjectName("statusbar")
PragrammingGUI.setStatusBar(self.statusbar)
self.retranslateUi(PragrammingGUI)
QtCore.QMetaObject.connectSlotsByName(PragrammingGUI)
def retranslateUi(self, PragrammingGUI):
_translate = QtCore.QCoreApplication.translate
PragrammingGUI.setWindowTitle(_translate("PragrammingGUI", "Programming"))
self.test_2.setText(_translate("PragrammingGUI", "TEST"))

if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
PragrammingGUI = QtWidgets.QMainWindow()
ui = Ui_PragrammingGUI()
ui.setupUi(PragrammingGUI)
PragrammingGUI.show()
sys.exit(app.exec_())

其中有浏览的是(忽略get_all_serials方法(：

from PyQt5.QtWidgets import QFileDialog, QDialog
from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_Test(QDialog):

self.lineEdit.setText(file_name[0])

self.serial = CameraID()
self.serial.getAllSerial()
return_list = self.serial.getAllSerial()
if len(return_list) > 0:
for i in return_list:
self.comboBox.addItem(i)
else:
self.comboBox.addItem("None")

self.lineEdit.setGeometry(QtCore.QRect(10, 10, 291, 21))
self.lineEdit.setObjectName("lineEdit")
self.lineEdit.setPlaceholderText("Chose file")
self.browseBtn = QtWidgets.QPushButton(self.centralwidget)#, clicked=lambda: self.browseBtn)
self.browseBtn.setGeometry(QtCore.QRect(310, 10, 80, 23))
self.browseBtn.setObjectName("browseBtn")
self.browseBtn.clicked.connect(self.browseBtn)
self.radioButton = QtWidgets.QRadioButton(self.centralwidget)
self.radioButton.setGeometry(QtCore.QRect(10, 40, 51, 21))
self.radioButton.setObjectName("radioButton")

self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(310, 40, 80, 23))
self.pushButton.setObjectName("pushButton")
self.comboBox = QtWidgets.QComboBox(self.centralwidget)
self.comboBox.setGeometry(QtCore.QRect(120, 40, 181, 23))
self.comboBox.setObjectName("comboBox")
Test.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(Test)

我认为问题是：self.browseBtn.clicked.connect(self.browseBtn)。您正在尝试将单击事件连接到按钮本身。

您可能想要执行以下操作：self.browseBtn.clicked.connect(self.method_to_call_when_clicked)，其中method_to_call_when_clicked将替换为您希望在单击时调用的方法的名称。

代码中已有一个示例：self.test_2.clicked.connect(self.open_test_window)
