PyQt5 QSpinBox – 获取子区域

在本文中,我们将了解如何获取子区域,子区域包含旋转框的子区域所占据的组合区域。为了做到这一点,我们使用childrenRegion方法。如果我们删除旋转框的所有子元素,则此属性将返回一个空区域。

为了做到这一点,我们使用 childrenRegion 方法。

注意:不包括隐藏的孩子

下面是实现

# 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 the children region
        children_region = self.spin.childrenRegion()
  
        # setting text to the label
        self.label.setText(str(children_region))
  
        # 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 :
