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 ：
