PyQt5 QSpinBox – 关闭更新
在本文中,我们将看到如何关闭旋转框的更新,关闭更新意味着它不会像值更改那样得到任何更新,甚至不会显示为show
方法也不会对其产生影响。默认情况下,旋转框的更新是开启的。
为此,我们使用setUpdatesEnabled
方法。
Syntax : spin_box.setUpdatesEnabled(False)
Argument : It takes bool 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, 250, 40)
# setting prefix to spin
self.spin.setPrefix("Prefix ")
# setting suffix to spin
self.spin.setSuffix(" Suffix")
# making spin box updates off
self.spin.setUpdatesEnabled(False)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
