Fixes #1 Review and test needed!

OK, I tested this and it works regarding the events occurring correctly, but I did find another issue.

Currently the code creates an array to store a list of events (pitft.pigameevs=[]). This array just keeps growing is size as items are never removed. EVDEV will eventually wrap around (I think the id is an integer) and there will be conflicts with duplicates.

I think the goal is to detect the MOUSEMOTION event from MOUSEBUTTONDOWN. A better way would be to just keep the buttondown/up state and toggle the state accordingly on a touch or lift. No more ever-growing array and it correctly distinguishes between events.

If you have another reason for storing the event IDs, let me know.

import pygame,pitft_touchscreen
from pygame.locals import *
pitft=pitft_touchscreen.pitft_touchscreen()
pitft.button_state=0
pitft.pl={'x':0,'y':0}
def init(rotation:int=90):
    pitft.pigamerotr=rotation
    pitft.start()
def run():
    while not pitft.queue_empty():
        for r in pitft.get_event():
            e={"y":(r["x"] if r["x"] else pitft.pl["x"]),"x":(r["y"] if r["y"] else pitft.pl["y"])}
            if e["x"] is None or e["y"] is None:
                break
            rel=(e["x"]-pitft.pl["x"],e["y"]-pitft.pl["y"])
            pitft.pl={"x":e["x"],"y":e["y"]}
            if pitft.pigamerotr==90:
                e={"x":e["x"],"y":240-e["y"]}
            elif pitft.pigamerotr==270:
                e={"x":320-e["x"],"y":e["y"]}
            else:
                raise(Exception("PiTft rotation is unsupported"))
            d={}
            t=MOUSEBUTTONUP if r["touch"]==0 else (MOUSEBUTTONDOWN if pitft.button_state == 0 else MOUSEMOTION)
            if t==MOUSEBUTTONDOWN:
                pitft.button_state = 1
                d["button"]=1
                d["pos"]=(e["x"],e["y"])
                pygame.mouse.set_pos(e["x"],e["y"])
            elif t==MOUSEBUTTONUP:
                pitft.button_state = 0
                d["button"]=1
                d["pos"]=(e["x"],e["y"])
            else:
                d["buttons"]=(True,False,False)
                d["rel"]=rel
                d["pos"]=(e["x"],e["y"])
                pygame.mouse.set_pos(e["x"],e["y"])
            pe=pygame.event.Event(t,d)
            pygame.event.post(pe)

If you want to create a branch and give me permission to edit in it, I can change code directly there.

[nift4]

I have a branch, but how allow editing?

[nift4]

Branch deleted, please make a fork! It's not easy on GitHub to do permission management per branch

[BroMarduk]

Will do.
