python-gui-pyqt5的使用方法-8--实际案例可参考使用

pyqt5的采用按钮和输入框（lineedit）可以完成简要的程序界面设计的工作：

pushbutton按钮功能：

1. self.pushButton.clicked.connect(lambda:self.onclickfun(x,y))

2. 通过lambda传送带参数的
   3… self.pushButton.clicked.connect(self.linedef)

   def linedef(self):
   name=self.lineEdit.text()
   yage=self.lineEdit_2.text()
   zadd=self.lineEdit_3.text()
   self.runedit(name,yage,zadd)
   # print(name,yage,zadd)

   def runedit(self,x,y,z):
   print("x is ",x+y+z)

lineedit输入框主要两个功能：
input = self.lineEdit.text() # 获取输入框的内容

    result = float(input) * 6
    self.lineEdit_2.setText(str(result))   # 设置输入框的内容

Runpragram.py --调用函数：

import sys
import pragram
from PyQt5.QtWidgets import QApplication, QMainWindow

if __name__ == '__main__':
    app = QApplication(sys.argv)
    mainwindow = QMainWindow()
    ui = pragram.Ui_MainWindow()
    ui.setupUi(mainwindow)
    mainwindow.show()

    sys.exit(app.exec_())

pragram.py --desinger花出来的界面----》生成代码：
