PyQt5 QSpinBox – Getting grab gesture

In this article we will see how we can set the grab gesture to the spin box. There are various grab gestures available for the spin box : tap gesture, a Tap-And-Hold (Long-Tap) gesture, a Pan gesture, a Pinch gesture, a Swipe gesture and a custom gesture. In order to do this we use grabGesture method with the spin box object.

Syntax : font_metrics.grabGesture(Qt.TapGesture) Argument : It takes gesture flag as argument Return : It returns None

Below is the implementation 

Python3

# 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(1, 999999)

        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")

        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")

        # setting grab gesture
        self.spin.grabGesture(Qt.TapGesture)



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
