大家好，欢迎来到IT知识分享网。

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：

PyQt5+Qt designer实战「建议收藏」

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：

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

# Form implementation generated from reading ui file 'clat.ui'
#
# Created by: PyQt5 UI code generator 5.6
#
# WARNING! All changes made in this file will be lost!

然后，新建Run.py文件，代码如下：

from PyQt5.QtWidgets import QApplication, QWidget, QMainWindow
from count.clat import Ui_Form


class mwindow(QWidget, Ui_Form):
    def __init__(self):
        super(mwindow, self).__init__()
        self.setupUi(self)

    def ps_bt(self):

    def ps_bt10(self):

    def ps_bt11(self):

    def ps_bt13(self):

    def ps_bt14(self):
        self.lineEdit.insert('7')

    def ps_bt15(self):
        self.lineEdit.insert('8')

    def ps_bt16(self):
        self.lineEdit.insert('9')

    def ps_bt17(self):
        self.lineEdit.backspace()

    def ps_bt19(self):

    def lineEdit_clear(self):
        self.lineEdit.clear()

    def calculate(self):
        # text = self.lineEdit.text()
        # self.lineEdit.setText('%s= %.2f' % (text, eval(text)))
        text = self.lineEdit.text()
        self.textBrowser.append('%s= %.2f' % (text, eval(text)))
        self.lineEdit_clear()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = mwindow()
    w.pushButton.clicked.connect(w.ps_bt)
    w.pushButton_1.clicked.connect(w.ps_bt1)
    w.pushButton_2.clicked.connect(w.ps_bt2)
    w.pushButton_3.clicked.connect(w.ps_bt3)
    w.pushButton_4.clicked.connect(w.ps_bt4)
    w.pushButton_5.clicked.connect(w.calculate)
    w.pushButton_6.clicked.connect(w.ps_bt6)
    w.pushButton_7.clicked.connect(w.ps_bt7)
    w.pushButton_8.clicked.connect(w.ps_bt8)
    w.pushButton_9.clicked.connect(w.ps_bt9)
    w.pushButton_10.clicked.connect(w.ps_bt10)
    w.pushButton_11.clicked.connect(w.ps_bt11)
    w.pushButton_12.clicked.connect(w.ps_bt12)
    w.pushButton_13.clicked.connect(w.ps_bt13)
    w.pushButton_14.clicked.connect(w.ps_bt14)
    w.pushButton_15.clicked.connect(w.ps_bt15)
    w.pushButton_16.clicked.connect(w.ps_bt16)
    w.pushButton_17.clicked.connect(w.ps_bt17)
    w.pushButton_18.clicked.connect(w.ps_bt18)
    w.pushButton_19.clicked.connect(w.ps_bt19)
    w.show()
    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：

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