PyQt5 QSpinBox - 访问最大值
在本文中,我们将看到如何获得最大值,即旋转框的上限,默认情况下,当我们创建一个旋转框时,它的范围是 0 到 99,即它的最大值是 99,尽管我们可以更改它。
为此,我们将使用spin_box.maximum
方法
Syntax : spin_box.maximum()
Argument : It takes no argument
Return : It returns integer i.e upper bond
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 maximum value
self.spin.setMaximum(5)
# creating label show result
self.label = QLabel(self)
# setting geometry
self.label.setGeometry(100, 200, 200, 40)
# getting max value
val = self.spin.maximum()
# setting text to the label
self.label.setText("Max Value : " + str(val))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
window.show()
# start the app
sys.exit(App.exec())
输出 :
