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 librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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("Lazyroar", self) # setting geometry to the label label.setGeometry(100, 200, 300, 80) # making label multi line label.setWordWrap(True)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
