網上關于PyQt5的教程很少，特別是界面跳轉這一塊兒，自己研究了半天，下來和大家分享一下
一、首先是主界面
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'Form.ui'
#
# Created by: PyQt5 UI code generator 5.10.1
#
# WARNING! All changes made in this file will be lost!
#要注意的是跳轉界面第二個必須使用QDialog類，不能使用QWidget，我也不知道為什么，特別注意
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication
import Dialog1
import Dialog2
import sys
class Ui_Form(object): #這是用PyQt Designer生成的代碼，很簡單的，拖動控件，生成ui文件，然后UIC轉換成py文件
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(440, 310)
self.form = Form
self.btn_d1 = QtWidgets.QPushButton(Form)
self.btn_d1.setGeometry(QtCore.QRect(60, 140, 75, 23))
self.btn_d1.setObjectName("btn_d1")
self.btn_d2 = QtWidgets.QPushButton(Form)
self.btn_d2.setGeometry(QtCore.QRect(180, 140, 75, 23))
self.btn_d2.setObjectName("btn_d2")
self.btn_exit = QtWidgets.QPushButton(Form)
self.btn_exit.setGeometry(QtCore.QRect(310, 140, 75, 23))
self.btn_exit.setObjectName("btn_exit")
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
self.btn_d1.setText(_translate("Form", "Demo1"))
self.btn_d1.clicked.connect(self.jump_to_demo1)
self.btn_d2.setText(_translate("Form", "Demo2"))
self.btn_d2.clicked.connect(self.jump_to_demo2)
self.btn_exit.setText(_translate("Form", "Exit"))
self.btn_exit.clicked.connect(self.exit)
def jump_to_demo1(self): #這一塊注意，是重點從主界面跳轉到Demo1界面，主界面隱藏，如果關閉Demo界面，主界面進程會觸發self.form.show()會再次顯示主界面
self.form.hide() #如果沒有self.form.show()這一句，關閉Demo1界面后就會關閉程序
form1 = QtWidgets.QDialog()
ui = Dialog1.Ui_Dialog1()
ui.setupUi(form1)
form1.show()
form1.exec_()
self.form.show()
def jump_to_demo2(self):
self.form.hide()
form2 = QtWidgets.QDialog()
ui = Dialog2.Ui_Dialog2()
ui.setupUi(form2)
form2.show()
form2.exec_()
self.form.show()
def exit(self):
self.form.close()
if __name__ == "__main__":
app = QApplication(sys.argv)
form = QtWidgets.QWidget()
window = Ui_Form()
window.setupUi(form)
form.show()
sys.exit(app.exec_())
二、跳轉界面Demo1
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'Dialog1.ui'
#
# Created by: PyQt5 UI code generator 5.10.1
#
# WARNING! All changes made in this file will be lost!
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Dialog1(object):
def setupUi(self, Dialog1):
Dialog1.setObjectName("Dialog1")
Dialog1.resize(400, 300)
self.dialog=Dialog1
self.pushButton = QtWidgets.QPushButton(Dialog1)
self.pushButton.setGeometry(QtCore.QRect(140, 140, 75, 23))
self.pushButton.setObjectName("pushButton")
self.retranslateUi(Dialog1)
QtCore.QMetaObject.connectSlotsByName(Dialog1)
def retranslateUi(self, Dialog1):
_translate = QtCore.QCoreApplication.translate
Dialog1.setWindowTitle(_translate("Dialog1", "Dialog"))
self.pushButton.setText(_translate("Dialog1", "Jump to main"))
self.pushButton.clicked.connect(self.jump_to_main)
def jump_to_main(self):
self.dialog.close()
三、跳轉界面Demo2
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'Dialog2.ui'
#
# Created by: PyQt5 UI code generator 5.10.1
#
# WARNING! All changes made in this file will be lost!
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QDialog, QApplication
import sys
class Ui_Dialog2(object):
def setupUi(self, Dialog2):
Dialog2.setObjectName("Dialog2")
Dialog2.resize(400, 300)
self.dialog = Dialog2
self.pushButton = QtWidgets.QPushButton(Dialog2)
self.pushButton.setGeometry(QtCore.QRect(140, 160, 75, 23))
self.pushButton.setObjectName("pushButton")
self.retranslateUi(Dialog2)
QtCore.QMetaObject.connectSlotsByName(Dialog2)
def retranslateUi(self, Dialog2):
_translate = QtCore.QCoreApplication.translate
Dialog2.setWindowTitle(_translate("Dialog2", "Dialog"))
self.pushButton.setText(_translate("Dialog2", "Jump to main"))
self.pushButton.clicked.connect(self.go_main)
def go_main(self):
self.dialog.close()
if __name__ == "__main__":
app = QApplication(sys.argv)
form = QtWidgets.QDialog()
ui = Ui_Dialog2()
ui.setupUi(form)
form.show()
sys.exit(app.exec_())
