In this article we will see how we can set stylesheet to the QDoubleSpinBox. Stylesheet is used to set color, background and various styling things of the double spin box. With style sheet we can add border to it and make our own customized double spin box.
In order to do this we will use setStyleSheet method with the double spin box object. Syntax : dd_spin.setStyleSheet(code) Argument : It takes string as argument Return : It returns None
Below is the example style sheet code
QDoubleSpinBox { border : 2px solid black; background : white; } QDoubleSpinBox::hover { border : 2px solid green; background : lightgreen; } QDoubleSpinBox::up-arrow { border : 1px solid black; background : blue; } QDoubleSpinBox::down-arrow { border : 1px solid black; background : red; }
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 , 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 style sheet to the double spin box
d_spin.setStyleSheet("QDoubleSpinBox"
"{"
"border : 2px solid black;"
"background : white;"
"}"
"QDoubleSpinBox::hover"
"{"
"border : 2px solid green;"
"background : lightgreen;"
"}"
"QDoubleSpinBox::up - arrow"
"{"
"border : 1px solid black;"
"background : blue;"
"}"
"QDoubleSpinBox::down - arrow"
"{"
"border : 1px solid black;"
"background : red;"
"}"
)
# 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 )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
