In this article we will see how we can get the maximum possible value to the QDoubleSpinBox. By default maximum possible value is <100 for double spin box. i.e user cant enter value greater or equal to the 100 although we can change this maximum value any time with the help of setMaximum
method. By changing the maximum value we allow user to enter value which is less than the maximum value.
In order to do this we will use
maximum
method with the double spin box object.Syntax : dd_spin.maximum()
Argument : It takes no argument
Return : It returns float
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 , 500 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# 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 decimal precision
d_spin.setDecimals( 1 )
# step type
step_type = QAbstractSpinBox.AdaptiveDecimalStepType
# adaptive step type
d_spin.setStepType(step_type)
# setting maximum value
d_spin.setMaximum( 9.9 )
# creating a label
label = QLabel( "GeeksforGeeks" , self )
# setting geometry to the label
label.setGeometry( 100 , 200 , 300 , 80 )
# making label multi line
label.setWordWrap( True )
# getting maximum value
value = d_spin.maximum()
# setting text to the label
label.setText( "Max Possible Value : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
