PyQT5 入门教学之1.1 开始设计界面和转换后_pyqt5界面设计变动后-优快云博客

本文详细介绍了如何使用PyQt5将.ui文件转换为可执行代码，并展示了具体的代码实现过程，包括如何设置窗口、按钮等组件，以及如何通过self.show()使窗口可见。

需要注意，转换后的文件不包括以下东西：

类的程序入口代码（面对对象编程下，用pyuic转换后只是你软件的图形化的类模块而已）
类中函数入口
把objects改成QMainWindow

还有关键是：
self.show()

我们来看看转换后的样子

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(1024, 657)
        self.send = QtWidgets.QPushButton(Dialog)
        self.send.setGeometry(QtCore.QRect(943, 610, 82, 51))
        self.send.setObjectName("send")


        self.retranslateUi(Dialog)#本地化
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "测试页"))
        self.send.setText(_translate("Dialog", "发送"))

首先看看启动方法：

1.添加if name == 'main’启动类的初始化

if __name__ == '__main__':
    QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)
    Imapp = QApplication(sys.argv)
    ex = Ui_IM()
    ex.show()
    sys.exit(Imapp.exec_())

2.在类中开始添加

     def __init__(self):
     	super().__init__()
     	self.setupUi(self)

3.添加self.show()

或者在

if __name__ == '__main__':

中添加

ex.show()

4.修改

class Ui_Dialog(object):

为

class Ui_Dialog(QMainWindow):

5.导入包

from PyQt5.QtWidgets import  QApplication,QMainWindow

完整代码：

from PyQt5 import QtCore, QtGui, QtWidgets,Qt
from PyQt5.QtWidgets import  QApplication, QPushButton, QMenu,QLineEdit,QMainWindow,QLabel
from PyQt5.QtCore import QCoreApplication,QTimer,QThread,pyqtSignal
from PyQt5.QtGui import QIcon, QPainter, QPixmap,QPalette,QBrush
import sys


class Ui_Dialog(QMainWindow):

    def __init__(self):
        super().__init__()
        self.setupUi(self)


    def setupUi(self, Dialog):
                Dialog.setObjectName("Dialog")
                Dialog.resize(1024, 657)
                Dialog.setStyleSheet("")
                self.send = QtWidgets.QPushButton(Dialog)
                self.send.setGeometry(QtCore.QRect(943, 610, 82, 51))
                self.send.setObjectName("send")

                self.retranslateUi(Dialog)
                QtCore.QMetaObject.connectSlotsByName(Dialog)
                #self.show()

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
        self.send.setText(_translate("Dialog", "发送"))


if __name__ == '__main__':
    QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)
    test = QApplication(sys.argv)
    ex = Ui_IM()
    ex.show()
    sys.exit(test.exec_())
