In this article we will see how we can check if the value appears in the center of spin box or not, when we create spin box the value is at the left hand side in order to make the value in center we have to set its alignment flag to center.
In order to do this we will use alignment
method.
Syntax : spin_box.alignment()
Argument : It takes no argument
Return : It returns Qt object
Steps for implementation –
1. Create a spin box
2. Set its alignment with the help of setAlignment
method
3. Create label to show the result
4. Get the alignment with the help of alignment
method
5. Check if alignment is center then update the label
6. Show alignment is not center show not at center
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 , 150 , 40 )
# alignment
alignment = Qt.AlignCenter
# setting alignment to centre
self .spin.setAlignment(alignment)
# creating label
label = QLabel( self )
# setting geometry to the label
label.setGeometry( 100 , 160 , 200 , 30 )
# getting alignment
get_alignment = self .spin.alignment()
# checking if alignment is centre
if get_alignment = = Qt.AlignCenter:
text = "Center Aligned"
else :
text = "Not center aligned"
# setting text to the label
label.setText(text)
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
