PyQt5实现界面(页面)跳转的示例代码

作者:Awzh

这篇文章主要介绍了PyQt5实现界面跳转的示例代码,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧

网上关于PyQt5的教程很少,特别是界面跳转这一块儿,自己研究了半天,下来和大家分享一下

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!
#要注意的是跳转界面第二个必须使用QDialog类,不能使用QWidget,我也不知道为什么,特别注意
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication
import Dialog1
import Dialog2
import sys


class Ui_Form(object): #这是用PyQt Designer生成的代码,很简单的,拖动控件,生成ui文件,然后UIC转换成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):    #这一块注意,是重点从主界面跳转到Demo1界面,主界面隐藏,如果关闭Demo界面,主界面进程会触发self.form.show()会再次显示主界面
    self.form.hide()      #如果没有self.form.show()这一句,关闭Demo1界面后就会关闭程序
    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、跳转界面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、跳转界面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_())
