【问题描述】：
我正在使用 pyqt5 构建一个 gui。我试图弄清楚如何每次点击更改按钮：
在我的代码中，我有一个名为 Chuck_Release 的按钮。基本上，我希望它在某些条件下显示“chuck”或“release”，但在那之前我只希望它每次点击都改变它的标题，开始状态为“chuck”，但我似乎无法弄清楚知道怎么做。
这是我的代码：
import sys, time
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(685, 459)
self.exitbtn = QtWidgets.QPushButton(Dialog)
self.exitbtn.setGeometry(QtCore.QRect(608, 431, 75, 23))
self.exitbtn.setObjectName("exitbtn")
self.Typelist = QtWidgets.QComboBox(Dialog)
self.Typelist.setGeometry(QtCore.QRect(50, 70, 59, 20))
self.Typelist.setObjectName("Typelist")
self.Typelist.addItem("")
self.Typelist.addItem("")
self.Typelist.addItem("")
self.Chuck_Release = QtWidgets.QPushButton(Dialog)
self.Chuck_Release.setGeometry(QtCore.QRect(50, 100, 75, 23))
self.Chuck_Release.setObjectName("Chuck_Release")
self.label = QtWidgets.QLabel(Dialog)
self.label.setGeometry(QtCore.QRect(50, 20, 37, 16))
self.label.setObjectName("label")
self.textBrowser = QtWidgets.QTextBrowser(Dialog)
self.textBrowser.setGeometry(QtCore.QRect(25, 160, 511, 192))
self.textBrowser.setObjectName("textBrowser")
self.lineEdit = QtWidgets.QLineEdit(Dialog)
self.lineEdit.setGeometry(QtCore.QRect(50, 40, 133, 20))
self.lineEdit.setObjectName("lineEdit")
self.Runbtn = QtWidgets.QPushButton(Dialog)
self.Runbtn.setGeometry(QtCore.QRect(420, 60, 91, 61))
font = QtGui.QFont()
font.setPointSize(16)
font.setBold(True)
font.setWeight(75)
self.Runbtn.setFont(font)
self.Runbtn.setObjectName("Runbtn")
self.getSerial = QtWidgets.QPushButton(Dialog)
self.getSerial.setGeometry(QtCore.QRect(200, 40, 75, 23))
self.getSerial.setObjectName("getSerial")
self.exitbtn.clicked.connect(self.exitclicked)
self.Chuck_Release.clicked.connect(self.chuckclicked)
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
def retranslateUi(self, Dialog):
_translate = QtCore.QCoreApplication.translate
Dialog.setWindowTitle(_translate("Dialog", "NEW GUI"))
self.exitbtn.setText(_translate("Dialog", "Exit"))
self.Typelist.setItemText(0, _translate("Dialog", "Type 1"))
self.Typelist.setItemText(1, _translate("Dialog", "Type2"))
self.Typelist.setItemText(2, _translate("Dialog", "Type 3"))
self.Chuck_Release.setText(_translate("Dialog", "Chuck"))
self.label.setText(_translate("Dialog", "Serial #"))
self.Runbtn.setText(_translate("Dialog", "Run"))
self.getSerial.setText(_translate("Dialog", "Enter"))
def exitclicked(self,Dialog):
sys.exit()
def chuckclicked(self,Dialog):
self.Chuck_Release.setText("Release") ***this is my function for chuckrelease push button***
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
Dialog = QtWidgets.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.show()
sys.exit(app.exec_())
如果有人可以向我解释如何完成它的过程，我会很高兴。 谢谢！ :D
