PyQt5 QSpinBox – Get the XOR region with Children region
In this article we will see how we can get the XOR i.e exclusive or with the children region of spin box and another region, children region holds the combined region occupied by the spin box’s children. In order to get the children region we use childrenRegion method. XOR region will be the new region with no intersection part below is representation of how xor region will look like.
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
Below is the implementation
# 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()) |
Output :
