PyQt5 QDoubleSpinBox - Установка для него Line Edit
In this article we will see how we can set the line edit to the QDoubleSpinBox. Line edit is the white space which receives the input and shows the current value of the double spin box, we can change the line edit object any time. Line edit is the main component of the double spin box the default line edit is made such that it receives only float values.
In order to do this we will use
setLineEditmethod with the double spin box object.Syntax : dd_spin.setLineEdit(lineedit)
Argument : It takes QLineEdit object as argument
Return : It returns None
Below is the implementation
# importing librariesfrom PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGuifrom 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) # line edit lineedit = QLineEdit(self) # setting line edit to the double spin box d_spin.setLineEdit(lineedit) # 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 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec()) |
