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()) |
Output :
