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 ()) |
