In this article we will see how we can clear the mask from the spin box, masks are used to hide part of a UI Image element. We can set mask using setMask method.
In order to do this we use cleanText method.
Syntax : spin_box.clearMask()
Argument : It takes no argument
Action Performed : It mask on the spin box
Implementation steps :
1. Create a main window
2. Create a spin box set its range prefix and suffix
3. Add mask to the spin box
4. Create a push button
5. Add action to the push button
6. Inside the action method call the clearMask method
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") # creating a push button push = QPushButton("Clear", self) # setting geometry to the push button push.setGeometry(100, 200, 100, 40) # adding action to the push button push.clicked.connect(self.push_action) # setting mask on spin box region = self.spin.childrenRegion() self.spin.setMask(region) # method called by the push button def push_action(self): # clearing the mask self.spin.clearMask() # 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()) |
