PyQt5 QSpinBox – 检查它是启用还是禁用
在本文中,我们将了解如何检查旋转框是启用还是禁用,禁用的旋转框基本上是无法编辑的旋转框,即禁用和启用的旋转框是正常的旋转框,默认旋转框是启用。为了使旋转框禁用,我们使用setDisabled
方法。
为此,我们使用isEnabled
方法。
Syntax : spin_box.isEnabled()
Argument : It takes no argument
Return : It returns bool
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")
# checking if spin box is enabled
check = self.spin.isEnabled()
# creating a label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 250, 30)
# setting text to label
label.setText("Enabled ? : " + str(check))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
