PyQt5 QSpinBox – 从子区域获取翻译区域

在本文中，我们将看到如何从旋转框的子区域中获取翻译区域，子区域包含旋转框的子区域所占据的组合区域。为了获得子区域，我们使用childrenRegion方法。平移区域表示沿 x 和 y 轴移动的子区域。

In order to do this we use translated method with the children region object of the spin box

Syntax : children_region.translated(x, y)

Argument : It takes two integer as argument

Return : It returns QRegion

注意：此方法类似于translate方法，但此方法不会对子区域进行更改。

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 range to the spin box
        self.spin.setRange(0, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # getting the children region
        children_region = self.spin.childrenRegion()
  
        # creating a label
        label = QLabel(self)
        label.setWordWrap(True)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 60)
  
        # getting translated region from the children region
        translated_region = children_region.translated(100, 100)
  
        # setting text to the label
        label.setText("Translated region : " + str(translated_region.rects()))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())

输出 ：
