PyQt5 QSpinBox – 设置最小值
在本文中,我们将看到如何设置最小值,即微调框的下限,默认情况下,当我们创建微调框时,它的范围是 0 到 99,即它的最小值为 0,尽管我们可以更改它。
为此,我们将使用spin_box.setMinimum
方法。
Syntax : spin_box.setMinimum(n)
Argument : It takes integer as argument
Return : It returns None
下面是实现
# 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, 600, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for widgets
def UiComponents(self):
# creating spin box
self.spin = QSpinBox(self)
# setting geometry to spin box
self.spin.setGeometry(100, 100, 100, 40)
# setting minimum value
self.spin.setMinimum(-10)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
