PyQt5 QSpinBox – 检查某些点是否在子区域内

在这篇文章中，我们将看到如何检查某个点是否在自旋盒的子区域中，子区域持有自旋盒的子区域所占据的组合区域。为了达到这个目的，我们使用childrenRegion方法。

注意： 该点应该在自旋盒的坐标系中。

为了做到这一点，我们使用包含旋转盒的子区域对象的方法。

语法： children_region.contains(point)

参数： 它需要QPoint对象作为参数。

返回： 它返回bool对象

以下是实现方法

# Write Python3 code here# 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 bounding rectangle from the children region
        bounding_rectangle = children_region.contains(QPoint(10, 10))
  
        # setting text to the label
        label.setText("Point 10, 10 of spin box is in the children region "
                      "? " + str(bounding_rectangle))
  
  
  
# 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 :
