篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了PyQt5-Qt Designer简易的数字键盘输入相关的知识,希望对你有一定的参考价值。
参考如下键盘格式写了一个键盘输入,目前还不能进行运算,后期完善。。。
效果如下:
完整代码:
from PyQt5.QtWidgets import (QApplication,QWidget,QPushButton,QLCDNumber,QFormLayout,QLineEdit,QLabel,QGridLayout) from PyQt5.QtGui import QFont from PyQt5.QtCore import Qt,QTimer,QDateTime,QDate,QTime,QSize import sys class Example(QWidget): def __init__(self): super(Example, self).__init__() self.initUI() def initUI(self): self.setGeometry(300,300,330,310) self.setWindowTitle("数字键盘输入") gridLayout = QGridLayout() self.display = QLineEdit("0") self.display.setFixedSize(QSize(287,40)) self.display.setReadOnly(True) self.display.setAlignment(Qt.AlignRight) self.display.setFont(QFont("微软雅黑",14,QFont.Bold)) gridLayout.addWidget(self.display,0,0,1,4) self.showNum = "" keys = [‘Clear‘, ‘/‘, ‘*‘, ‘-‘, ‘7‘, ‘8‘, ‘9‘, ‘+‘, ‘4‘, ‘5‘, ‘6‘, ‘‘, ‘1‘, ‘2‘, ‘3‘, ‘Enter‘, ‘0‘, ‘‘, ‘.‘, ‘‘] position = [(0, 0), (0, 1), (0, 2), (0, 3), (1, 0), (1, 1), (1, 2), (1, 3), (2, 0), (2, 1), (2, 2), (2, 2), (3, 0), (3, 1), (3, 2), (3, 3), (4, 0), (4, 1), (4, 2), (4, 3), ] for item in range(len(keys)): btn = QPushButton(keys[item]) btn.setFixedSize(QSize(60, 40)) btn.setFont(QFont("微软雅黑",12,QFont.Bold)) btn.clicked.connect(self.btnClicked) if keys[item] == "+": gridLayout.addWidget(btn, 2, 3, 2, 1) btn.setFixedSize(QSize(60, 90)) elif keys[item] == "Enter": gridLayout.addWidget(btn, 4, 3, 2, 1) btn.setFixedSize(QSize(60, 90)) elif keys[item] == "0": gridLayout.addWidget(btn, 5, 0, 1, 2) btn.setFixedSize(QSize(142, 40)) elif keys[item] == "": continue else: gridLayout.addWidget(btn, position[item][0]+1, position[item][1], 1, 1) self.setLayout(gridLayout) def btnClicked(self): sender = self.sender() symbols = ["Clear","/","*","-","+","Enter"] if sender.text() not in symbols: self.showNum += sender.text() self.display.setText(self.showNum) elif sender.text() == "Clear": self.display.setText("0") self.showNum = "" if __name__ == ‘__main__‘: app = QApplication(sys.argv) ex = Example() ex.show() sys.exit(app.exec_())
