In this article we will see how we can get the minimum possible value of the QDoubleSpinBox. By default minimum possible value is 0 for double spin box. i.e user cant enter value less than 0 although we can change this maximum value any time with the help of setMinimum method. By changing the minimum value we allow user to enter value which is greater than the minimum value.
In order to do this we will use
minimummethod with the double spin box object.Syntax : dd_spin.minimum()
Argument : It takes no argument
Return : It returns float value
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 minimum value d_spin.setMinimum(25.5) # creating a label label = QLabel("neveropen", self) # setting geometry to the label label.setGeometry(100, 200, 300, 80) # making label multi line label.setWordWrap(True) # getting minimum value value = d_spin.minimum() # setting text to the label label.setText("Min 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()) |
Output :
