PyQt5 QSpinBox – 检查某个区域是否与子区域相交
在本文中,我们将看到如何检查某个区域是否可以是 QRect 或 QRegion 与旋转框的子区域相交,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。
In order to do this we use intersects method with the children region object of the spin box
Syntax : children_region.intersects(rectangle)
Argument : It takes QRect object as argument also it can take QRegion object
Return : It returns bool
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)
# QRect
rectangle = QRect(1, 1, 20, 30)
# checking if rectangle intersects the children region
check = children_region.intersects(rectangle)
# setting text to the label
label.setText("Intersects ? : " + str(check))
# 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 :
