PyQt5 QSpinBox – 移除箭头按钮

在本文中，我们将了解如何删除微调框的按钮，基本上微调框中有两个按钮，一个用于递增值，第二个用于递减值。下面是正常旋转框的外观与没有按钮的旋转框的外观示意图

为此，我们将使用setButtonSymbols方法。

Syntax :
spin_box.setButtonSymbols(QAbstractSpinBox.NoButtons)
or
spin_box.setButtonSymbols(2)

Argument : It takes either QAbstractSpinBox object or integer value

Return : None

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, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 150, 40)
  
        # removing the buttons
        self.spin.setButtonSymbols(QAbstractSpinBox.NoButtons)
          
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
