PyQt5 QSpinbox – 检查是否启用了接受滴落功能
在这篇文章中,我们将看到如何检查旋转盒中的接受滴落是否被启用,我们使用setAcceptDrops方法来启用接受滴落。为了检查旋转盒的接受液滴属性是否被启用,我们使用acceptDrops方法。
为了做到这一点,我们在旋转盒中使用acceptDrops方法。
语法: line_edit.acceptDrops()
参数: 它不需要参数
返回: 它返回bool
下面是实现方法
# 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 accept drop enabled
self.spin.setAcceptDrops(True)
# creating a label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 200, 30)
# checking if accept drop is enabled
check = self.spin.acceptDrops()
# setting text to the label
label.setText("Accept drop 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:
