本节主要介绍如何使用PyQt输入对话框获取数据，包括对int、double、下拉列表和字符串输入类型数据的处理

import sys
    from PyQt5.QtWidgets import QApplication, QWidget, QInputDialog, QLineEdit
    
    
    class App(QWidget):
        # 初始化窗口参数
        def __init__(self):
            super().__init__()
            self.title = 'PyQt5 input dialogs'
            self.left = 10
            self.top = 10
            self.width = 640
            self.height = 480
            self.initUI()
    
        def initUI(self):
            self.setWindowTitle(self.title)
            self.setGeometry(self.left, self.top, self.width, self.height)
    
            self.getInteger()
            self.getText()
            self.getDouble()
            self.getChoice()
    
            self.show()
    
        def getInteger(self):
            # 输入int类型
            i, okPressed = QInputDialog.getInt(self, "Get integer", "Percentage:", 28, 0, 100, 1)
            if okPressed:
                print(i)
    
        def getDouble(self):
            # 输入double类型
            d, okPressed = QInputDialog.getDouble(self, "Get double", "Value:", 10.50, 0, 100, 10)
            if okPressed:
                print(d)
    
        def getChoice(self):
            items = ("Red", "Blue", "Green")
            # 输入下拉列表类型
            item, okPressed = QInputDialog.getItem(self, "Get item", "Color:", items, 0, False)
            if okPressed and item:
                print(item)
    
        def getText(self):
            # 输入文本类型
            text, okPressed = QInputDialog.getText(self, "Get text", "Your name:", QLineEdit.Normal, "")
            if okPressed and text != '':
                print(text)
    
    
    if __name__ == '__main__':
        app = QApplication(sys.argv)
        ex = App()
        sys.exit(app.exec_())
