pyqt5 QInputDialog 简单例子

代码如下:

import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *

class InputdialogDemo(QWidget):
	def __init__(self, parent=None):
		super(InputdialogDemo, self).__init__(parent)
		layout = QFormLayout()
		self.btn1 = QPushButton("获得列表里的选项")
		self.btn1.clicked.connect(self.getItem)
		self.le1 = QLineEdit()
		layout.addRow(self.btn1,self.le1)

		self.btn2 = QPushButton("获得字符串")
		self.btn2.clicked.connect(self.getIext)
		self.le2 = QLineEdit()
		layout.addRow(self.btn2,self.le2)

		self.btn3 = QPushButton("获得整数")
		self.btn3.clicked.connect(self.getInt)
		self.le3 = QLineEdit()
		layout.addRow(self.btn3,self.le3)
		self.setLayout(layout)
		self.setWindowTitle("Input Dialog 例子")
		
	def getItem(self):
		items = ("C", "C++", "Java", "Python")
		item, ok = QInputDialog.getItem(self, "select input dialog",
		"语言列表", items, 0, False)
		if ok and item:
			self.le1.setText(item)
	
	def getIext(self):	
		text, ok = QInputDialog.getText(self, 'Text Input Dialog', '输入姓名:')
		if ok:
			self.le2.setText(str(text)) 

	def getInt(self):
		num,ok = QInputDialog.getInt(self,"integer input dualog","输入数字")
		if ok:
			self.le3.setText(str(num))
					
if __name__ == '__main__':
	app = QApplication(sys.argv)
	demo = InputdialogDemo()
	demo.show()
	sys.exit(app.exec_())

还是需要 找本书 系统的学一下,不然 这种标准控件不知道, 只能自己去实现了
