阅读更多关于 python tkinter: detecting horizontal scrolling on touchpad

问题 i have a (large) python tkinter canvas. Navigation with arrow keys and (shift-)mousewheel is straight forward. But I would like to do it aswell via two fingers on the tochpad of a laptop. Today I found this to recognize horizontal scrolling (Ubuntu 16.04 LTS, Python 2.x): from Tkinter import * class MyAnything(): def __init__(self): self.root = Tk() self.root.bind('<Button>', self.on_pressed_button) self.root.mainloop() def on_pressed_button(self, event): print(event.num) if __name__ == '_

I'm trying to design a simple calculator for use as a scoreboard for a game or two. Ultimately, I want to be able to select the number of players, have that many score-trackers appear on screen, be able to use a the touch calculator to add or subtract (or divide or multiply) I got it to work for the most part.

No matter on what technology/language it is written I know this isn't what you want to hear, but there is no all-inclusive way to do what you want. Individual makes and models have their own way of exposing it. For example, I've done some work with Synaptic touchpads (fairly common) which expose a COM interface on Windows. That code won't work on any other

Detect touchpad vs mouse in Javascript

Is there any way to detect if the client is using a touchpad vs. a mouse with Javascript? Or at least to get some reasonable estimate of the number of users that use touchpads as opposed to mice? In the general case, there is no way to do what you want. ActiveX might allow you to see and examine USB devices, but in the best case, even if that is somehow possible, that limits you to IE users. Beyond that, there is no way to know. You might be able to discern patterns in how (or how often) a touchpad user moves the cursor versus how a mouse user might move the cursor. Differentiating between
