PyQt5 QDoubleSpinBox – 检查它是否可编辑
在本文中,我们将了解如何在 QDoubleSpinBox 不可编辑或可编辑的情况下进行操作。默认情况下,当我们创建一个双旋转框时,它是可编辑的,即用户可以随时更改其值,尽管通过setReadOnly
方法使其不可编辑,则其值无法更改,用户只能查看价值。
In order to do this we will use isReadOnly
method with the double spin box object.
Syntax : dd_spin.isReadOnly()
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, 500, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for components
def UiComponents(self):
# creating double spin box
d_spin = QDoubleSpinBox(self)
# setting geometry to the double spin box
d_spin.setGeometry(100, 100, 150, 40)
# setting decimal precision
d_spin.setDecimals(1)
# step type
step_type = QAbstractSpinBox.AdaptiveDecimalStepType
# adaptive step type
d_spin.setStepType(step_type)
# making it non editable
d_spin.setReadOnly(True)
# creating a label
label = QLabel("GeeksforGeeks", self)
# setting geometry to the label
label.setGeometry(100, 200, 300, 80)
# making label multi line
label.setWordWrap(True)
# checking if it is non editable
value = d_spin.isReadOnly()
# setting text to the label
label.setText("Non Editable ? : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
