PyQt5 QDoubleSpinBox – 获取整个文本
在本文中,我们将了解如何获取 QDoubleSpinBox 的整个文本。我们可以借助value
方法获取双旋转框的当前值,但它只获取值而不是前缀和后缀部分。整个文本是指双旋转框中的文本,即前缀、值和后缀都包括在内。
In order to do this we will use text
method with the double spin box object.
Syntax : dd_spin.text()
Argument : It takes no argument
Return : It returns string
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 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)
# getting whole text
value = d_spin.text()
# setting text to the label
label.setText("Text : " + 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 :
