Hook Mouse clicks and intercept them

I am currently trying to stop mouse clicks while my Script is running and still work with them.
If you are confused about the use case I will elaborate at the end of the question.
Currently I can get clicks like this:
import mouse
import time
def mouseHook(event):
if type(event) == mouse.ButtonEvent:
print(event)
mouse.hook(mouseHook)
while 1:
time.sleep(0.25)
But this still lets the clicks go through, how would I intercept them?
use case: simulate a monitor and while mouse is on that monitor send all movements, clicks and keypresses to MacBook (similar to Synergy, Mouse without Borders or Share Mouse)

The hook used by the application only 'hooks' into the process, which means it gets information from it, but can't insert or modify it's code.
For reference on windows that would use (https://learn.microsoft.com/en-us/previous-versions/windows/desktop/legacy/ms644988(v=vs.85))
The easiest way would be to have your application ignore the mouseclicks.

How to run mouse and keyboard events in a minimized window

I am looking for a way to run mouse and keyboard events in a minimized window, simple as that - the code does something in a specific window, while my computer is free - I can search the web and do whatever; I need Python 2 specifically, but open for 3 suggestions too; This is for automatization of certain tasks I have, I managed to make it work while my computer is in use, but now I need to run it in the background.
Thank you in advance.

Create a delay between mouse clicks using Autokey

I am about to switch from Windows to Ubuntu. Since my mouse keeps doing multiple clicks each time I press the middle mouse button, I used AutoHotkey under Windows to add a delay after each click. This worked fine. Now under Ubuntu I want to use AutoKey to do the same. Autokey uses Python for its scripts though.
Here is the AutoHotkey script:
MButton::
If (A_TimeSincePriorHotkey < 200)
Return
Send {MButton}
Return

Currently, (as of version 0.95.4), this is not possible from within AutoKey, because it can’t handle mouse buttons as hotkeys.

Emulate a mouse click without using the actual mouse on linux

I am working with a program that collects a lot of data then shows it to you in the program. Unfortunately, the program is poorly designed and requires you to "approve" each bit of data collected manually by clicking a checkbox to approve it. In order to automate this process, I wrote a small script that scans for a checkbox, clicks it, then clicks "next item".
Unfortunately, this requires moving the actual mouse, meaning I can't use my computer until the program has finished. There are other questions that reference automating this with the winapi, however none of these work on Linux. What is a way to automate this on Linux?

You can simply start the program in a separate X server, for example using xvfb with
xvfb-run YOUR_PROGRAM
If you want to wrap just the instrumented program, that's possible too:
export DISPLAY=:42
Xvfb :42
THE_INSTRUMENTED_PROGRAMM
xdotool mousemove 1 1 click 1 # your instrumentation goes here

How can I disable the mouse for a given amount of time?

I'm developing a rather big GUI with Tkinter for my cocktail-robot and now I'm trying to disable the mouse for a few seconds, so that no click on the screen will cause any event.
The reason why I need to do this is that the programm crashes if there're to much incoming events. Because I'm using time.sleep() for a few seconds, Windows thinks that the programm crashed and asks whether it should be closed.
Is there any possibilty to do that? Can I just bind the whole screen to "< Button-1 >"
Btw. the GUI is based on this structure:

I'm looking forward to your help! Thanks
