PyQt5 QSpinBox – 获取子节点列表
在这篇文章中,我们将看到如何获得旋转盒的子代,子代基本上是旋转盒的组件,例如,旋转盒的主要组件是它的QLineEdit,用于查看值和设置值。
为了实现这一目的,我们使用children方法。
语法: spin_box.children()
参数: 它不需要参数
返回: 它返回列表
以下是实现方法
# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
# setting title
self.setWindowTitle("Python ")
# setting geometry
self.setGeometry(100, 100, 600, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for widgets
def UiComponents(self):
# creating spin box
self.spin = QSpinBox(self)
# setting geometry to spin box
self.spin.setGeometry(100, 100, 250, 40)
# setting prefix to spin
self.spin.setPrefix("Prefix ")
# setting suffix to spin
self.spin.setSuffix(" Suffix")
# creating a label
self.label = QLabel("Label ", self)
# setting geometry to the label
self.label.setGeometry(100, 200, 200, 70)
# getting all the children of the spin box
children = self.spin.children()
# setting text to the label
self.label.setText(str(children))
# making label multi line
self.label.setWordWrap(True)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出:
