PyQt5 QDoubleSpinBox – 为其设置行编辑
在这篇文章中,我们将看到如何为QDoubleSpinBox设置行编辑。行编辑是接收输入并显示双旋盒当前值的空白区域,我们可以随时改变行编辑对象。行编辑是双旋盒的主要组成部分,默认的行编辑是只接收浮点值的。
为了做到这一点,我们将使用双旋盒对象的setLineEdit方法。
语法: dd_spin.setLineEdit(lineedit)
参数: 它需要QLineEdit对象作为参数。
返回: 它返回无。
下面是实现方法
# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui

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)
# line edit
lineedit = QLineEdit(self)
# setting line edit to the double spin box
d_spin.setLineEdit(lineedit)
# 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)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
