PyQt5 QSpinBox – 检查平板跟踪是否被激活

在本文中，我们将了解如何检查旋转框是否启用了平板电脑跟踪。默认情况下，平板电脑跟踪处于关闭状态。如果关闭了数位板跟踪，则仅当触笔与数位板接触或在触笔移动时至少按下一个触笔按钮时才会发生数位板移动事件。如果打开了数位板跟踪，即使触控笔悬停在数位板附近且未按下任何按钮，数位板移动事件也会发生。

为了做到这一点，我们使用带有旋转框对象的hasTabletTracking方法。

Syntax : spin_box.hasTabletTracking()

Argument : It takes no argument

Return : It returns bool

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, 250, 40)
  
        # setting range to the spin box
        self.spin.setRange(1, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
  
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
  
        # creating a label
        label = QLabel(self)
  
        # making the label multi line
        label.setWordWrap(True)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 60)
  
        # checking if spin box has tablet tracking 
        check = self.spin.hasTabletTracking()
  
        # setting text to the label
        label.setText("Has Tablet Tracking ? " + str(check))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
