PyQt5 QDoubleSpinBox – 清洁文本
在这篇文章中,我们将看到如何清洁QDoubleSpinBox的文本。我们可以在clean text属性的帮助下清理文本,这个属性保存了旋转框的文本,不包括任何前缀、后缀、前导或尾随的空白。
为了做到这一点,我们将使用double spin box对象的cleanText方法。
语法: dd_spin.cleanText()
参数: 它不需要参数
返回: 它返回字符串
以下是实现方法
# 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, 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 suffix
d_spin.setSuffix(" value")
# step type
step_type = QAbstractSpinBox.AdaptiveDecimalStepType
# adaptive step type
d_spin.setStepType(step_type)
# 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)
# push button
push = QPushButton("Press", self)
# setting geometry to the push button
push.setGeometry(100, 150, 100, 35)
# adding action to the push button
# showing clean text
push.clicked.connect(lambda: label.setText(d_spin.cleanText()))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
