qtdesigner 设计计算器后按数字无反应python

PyQt5+Qt designer 制作计算器

配置说明：

Anaconda 4.2.0 (64-bit)

Python 3.5.2

首先，在Qt designer里面设计界面：

打开 Qt designer后，设计界面如下所示：

保存为clat.ui。然后将其转为py文件：

之后会生产clat.py文件。

打开后，代码如下：

  1. # -*- coding: utf-8 -*-
  2.  
  3. # Form implementation generated from reading ui file 'clat.ui'
  4. #
  5. # Created by: PyQt5 UI code generator 5.6
  6. #
  7. # WARNING! All changes made in this file will be lost!
  8.  
  9. from PyQt5 import QtCore, QtGui, QtWidgets
  10.  
  11. class Ui_Form(object):
  12.     def setupUi(self, Form):

  116.         self.pushButton.setText(_translate("Form", "清除缓存"))
  117.

然后，新建Run.py文件，代码如下：

  1. import sys
  2. from PyQt5.QtWidgets import QApplication, QWidget, QMainWindow
  3. from count.clat import Ui_Form
  4.  
  5.  
  6. class mwindow(QWidget, Ui_Form):
  7.     def __init__(self):
  8.         super(mwindow, self).__init__()
  9.         self.setupUi(self)
  10.  
  11.     def ps_bt(self):
  12.         self.textBrowser.clear()
  13.  
  14.     def ps_bt1(self):
  15.         self.lineEdit.insert('/')
  16.  
  17.     def ps_bt2(self):
  18.         self.lineEdit.insert('*')
  19.  
  20.     def ps_bt3(self):
  21.         self.lineEdit.insert('+')
  22.  
  23.     def ps_bt4(self):
  24.         self.lineEdit.insert('-')
  25.  
  26.     def ps_bt5(self):
  27.         self.lineEdit.insert('=')
  28.         self.calculate()
  29.  
  30.     def ps_bt6(self):
  31.         self.lineEdit.insert('.')
  32.  
  33.     def ps_bt7(self):
  34.         self.lineEdit.insert('0')
  35.  
  36.     def ps_bt8(self):
  37.         self.lineEdit.insert('1')
  38.  
  39.     def ps_bt9(self):
  40.         self.lineEdit.insert('2')
  41.  
  42.     def ps_bt10(self):
  43.         self.lineEdit.insert('3')
  44.  
  45.     def ps_bt11(self):
  46.         self.lineEdit.insert('4')
  47.  
  48.     def ps_bt12(self):
  49.         self.lineEdit.insert('5')
  50.  
  51.     def ps_bt13(self):
  52.         self.lineEdit.insert('6')
  53.  
  54.     def ps_bt14(self):
  55.         self.lineEdit.insert('7')
  56.  
  57.     def ps_bt15(self):
  58.         self.lineEdit.insert('8')
  59.  
  60.     def ps_bt16(self):
  61.         self.lineEdit.insert('9')
  62.  
  63.     def ps_bt17(self):
  64.         self.lineEdit.backspace()
  65.  
  66.     def ps_bt18(self):
  67.         self.lineEdit.clear()
  68.  
  69.     def ps_bt19(self):
  70.         self.close()
  71.  
  72.     def lineEdit_clear(self):
  73.         self.lineEdit.clear()
  74.  
  75.     def calculate(self):
  76.         # text = self.lineEdit.text()
  77.         # self.lineEdit.setText('%s= %.2f' % (text, eval(text)))
  78.         text = self.lineEdit.text()
  79.         self.textBrowser.append('%s= %.2f' % (text, eval(text)))
  80.         self.lineEdit_clear()
  81.  
  82.  
  83. if __name__ == '__main__':
  84.     app = QApplication(sys.argv)
  85.     w = mwindow()
  86.     w.pushButton.clicked.connect(w.ps_bt)
  87.     w.pushButton_1.clicked.connect(w.ps_bt1)
  88.     w.pushButton_2.clicked.connect(w.ps_bt2)
  89.     w.pushButton_3.clicked.connect(w.ps_bt3)
  90.     w.pushButton_4.clicked.connect(w.ps_bt4)
  91.     w.pushButton_5.clicked.connect(w.calculate)
  92.     w.pushButton_6.clicked.connect(w.ps_bt6)
  93.     w.pushButton_7.clicked.connect(w.ps_bt7)
  94.     w.pushButton_8.clicked.connect(w.ps_bt8)
  95.     w.pushButton_9.clicked.connect(w.ps_bt9)
  96.     w.pushButton_10.clicked.connect(w.ps_bt10)
  97.     w.pushButton_11.clicked.connect(w.ps_bt11)
  98.     w.pushButton_12.clicked.connect(w.ps_bt12)
  99.     w.pushButton_13.clicked.connect(w.ps_bt13)
  100.     w.pushButton_14.clicked.connect(w.ps_bt14)
  101.     w.pushButton_15.clicked.connect(w.ps_bt15)
  102.     w.pushButton_16.clicked.connect(w.ps_bt16)
  103.     w.pushButton_17.clicked.connect(w.ps_bt17)
  104.     w.pushButton_18.clicked.connect(w.ps_bt18)
  105.     w.pushButton_19.clicked.connect(w.ps_bt19)
  106.     w.show()
  107.     sys.exit(app.exec_())

运行Run.py，可在里面进行数值计算：

另外，如果想加入界面背景，并且自适应界面的大小，可以在主文件里面这么写：

  1.     def resizeEvent(self, event):
  2.         palette = QPalette()
  3.         pix = QPixmap('resources/background.jpg')
  4.         pix = pix.scaled(self.width(), self.height())
  5.         palette.setBrush(QPalette.Background, QBrush(pix))
  6.         self.setPalette(palette)
