Interface switching based on pyqt5 toolbar button -2

Pyqt5 yes Python A visual super easy-to-use library , Next, let's take a look at how to realize the toolbar button switching interface . This chapter mainly introduces how to implement the code , Don't talk much , Begin to introduce .

1. Use pyUIC Tools will mainwindow.ui Convert to “.py” file , The code is as follows ：

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'mainwindow.ui'
#
# Created by: PyQt5 UI code generator 5.15.4
#
# WARNING: Any manual changes made to this file will be lost when pyuic5 is
# run again.  Do not edit this file unless you know what you are doing.


from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.widget = QtWidgets.QWidget(self.centralwidget)
        self.widget.setGeometry(QtCore.QRect(10, 10, 781, 501))
        palette = QtGui.QPalette()
        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))
        brush.setStyle(QtCore.Qt.SolidPattern)

        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Inactive, QtGui.QPalette.Window, brush)
        brush = QtGui.QBrush(QtGui.QColor(255, 255, 127))
        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Base, brush)
        brush = QtGui.QBrush(QtGui.QColor(255, 255, 127))

        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Window, brush)
        self.widget.setPalette(palette)
        self.widget.setAutoFillBackground(True)
        self.widget.setObjectName("widget")
        self.widget_2 = QtWidgets.QWidget(self.widget)
        self.widget_2.setGeometry(QtCore.QRect(160, 110, 451, 231))
        palette = QtGui.QPalette()
        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))
        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Base, brush)
        brush = QtGui.QBrush(QtGui.QColor(0, 255, 255))
        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Window, brush)
        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))

        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Base, brush)
        brush = QtGui.QBrush(QtGui.QColor(0, 255, 255))
        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Window, brush)
        self.widget_2.setPalette(palette)
        self.widget_2.setAutoFillBackground(True)
        self.widget_2.setObjectName("widget_2")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)
        self.toolBar = QtWidgets.QToolBar(MainWindow)
        self.toolBar.setObjectName("toolBar")
        MainWindow.addToolBar(QtCore.Qt.TopToolBarArea, self.toolBar)
        self.action_1 = QtWidgets.QAction(MainWindow)
        self.action_1.setObjectName("action_1")
        self.action_2 = QtWidgets.QAction(MainWindow)
        self.action_2.setObjectName("action_2")
        self.toolBar.addAction(self.action_1)
        self.toolBar.addAction(self.action_2)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.toolBar.setWindowTitle(_translate("MainWindow", "toolBar"))
        self.action_1.setText(_translate("MainWindow", " Open the interface 1"))
        self.action_2.setText(_translate("MainWindow", " Open the interface 2"))

2. stay main.py Enter the following code in ：

import sys
from mainwindow import Ui_MainWindow
from PyQt5 import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import QHeaderView, QTableWidgetItem, QHBoxLayout

class MainUI(Ui_MainWindow, QMainWindow):
    def __init__(self, parent=None):
        super(MainUI, self).__init__(parent)
        self.setupUi(self)
    def openM(self):
        self.widget.show()
        self.widget_2.hide()
    def openC(self):
        self.widget_2.show()
        self.widget.show()

if __name__ == "__main__":
    app = QApplication(sys.argv)
    main = MainUI()
    main.show()
    main.action_1.triggered.connect(main.openM)
    main.action_2.triggered.connect(main.openC)
    sys.exit(app.exec_())

3. The interface implemented is as follows , Open the interface 1, Interface 1 appear , Interface 2 hide , Open the interface 2, Interface 1 hide , Interface 2 appear .

  summary

  After two chapters of detailed introduction , Under the same form , Switching between two interfaces , At the same time, the button is placed in the toolbar , Neat and beautiful .
