PyQt5 QSpinBox – 获取带有子区域的异或区域
在本文中,我们将看到如何获得异或,即独占或与旋转框的子区域和另一个区域,子区域包含旋转框的子区域所占用的组合区域。为了获得子区域,我们使用childrenRegion
方法。 XOR 区域将是没有交集的新区域,下面的部分表示 xor 区域的外观。
In order to do this we use xored method with the children region object of the spin box
Syntax : children_region.xored(region)
Argument : It takes QRegion object as argument
Return : It returns None
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, 80)
# QRegion
region = QRegion(QRect(40, 10, 40, 50))
# getting XOR region
children_region = children_region.xored(region)
# setting text to the label
label.setText("XOR Rectangles : " + str(children_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 :
