PyQt5 QSpinBox - Checking if tablet tracking is activated or not

Trying to figure out if a tablet's tracking (like a drawing tablet) is activated while using a QSpinBox in PyQt5.

PyQt5 doesn't have direct built-in functionality to differentiate between input from a mouse, a touchscreen, or a drawing tablet. However, you can use event properties and type checks to discern them to a certain extent.

Here's an outline of how you might approach this:

  1. Reimplement the event handlers: Override the default event handlers (like mousePressEvent, mouseMoveEvent, etc.) for the QSpinBox or any other widget you're interested in.

  2. Examine the event: Check the event type and the properties of the event object to determine the source of the input.

Here's a simple example using a QSpinBox and the mousePressEvent:

import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QSpinBox from PyQt5.QtCore import Qt from PyQt5.QtGui import QMouseEvent, QTabletEvent class CustomSpinBox(QSpinBox): def mousePressEvent(self, event: QMouseEvent): if event.type() == QEvent.TabletPress: print("Tablet pressed!") elif event.type() == QEvent.MouseButtonPress: print("Mouse button pressed!") super().mousePressEvent(event) class MainWindow(QMainWindow): def __init__(self): super().__init__() self.spinBox = CustomSpinBox(self) self.setCentralWidget(self.spinBox) app = QApplication(sys.argv) window = MainWindow() window.show() sys.exit(app.exec_())

Please note that this method isn't foolproof. For more accurate detection of tablet input, you would ideally use a library specifically designed to handle tablet input or use platform-specific APIs.

Also, remember that not all tablets or touchscreen devices will emit tablet events, and there are a wide variety of devices out there. Always test with multiple devices if possible to ensure compatibility.
