In this article we will see how we can select the value of the QDoubleSpinBox. Double spin box value can be selected with the help of mouse, only selecting value means to select only value part prefix and suffix will not be included in the selected part. The selected text can be use for copy/delete functions. Prefix and suffix can be added to the double spin box with the help of setPrefix and setSuffix method respectively.

In order to do this we will use selectAll method with the double spin box object.

Syntax : dd_spin.selectAll()

Argument : It takes no argument

Return : It returns None

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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
        # calling method
        # showing all the widgets
    # method for components
    def UiComponents(self):
        # creating double spin box
        d_spin = QDoubleSpinBox(self)
        # setting geometry to the double spin box
        d_spin.setGeometry(100, 100, 150, 40)
        # setting suffix
        d_spin.setSuffix(" is the Value")
        # step type
        step_type = QAbstractSpinBox.AdaptiveDecimalStepType
        # adaptive step type
        # creating a label
        label = QLabel("GeeksforGeeks", self)
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)
        # making label multi line
        # push button
        push = QPushButton("Press", self)
        # setting geometry to the push button
        push.setGeometry(100, 150, 100, 35)
        # adding action to the push button
        # selecting only value
        push.clicked.connect(lambda: d_spin.selectAll())
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
