combining tkinter and watchdog - python-3.x

Question

I'm trying the following
Create a GUI with tkinter where the user will choose a directory to watch
Close the window
Pass the path to the directory to watchdog so it can watch for file changes
How does one go about combining both scripts into one app ?
This below post has a script which does nothing when I add a *.jpg file to my temp folder (osx).

Can someone point me towards a course or tutorial that will help me understand how to combine whats going on.
1. GUI :
from tkinter import *
from tkinter.filedialog import askopenfilename
from tkinter import filedialog
from tkinter.messagebox import showerror
globalPath = ""
class MyFrame(Frame):
def __init__(self):
Frame.__init__(self)
self.master.title("Example")
self.master.rowconfigure(5, weight=1)
self.master.columnconfigure(5, weight=1)
self.grid(sticky=W+E+N+S)
self.button = Button(self, text="Browse", command=self.load_file, width=10)
self.button.grid(row=1, column=0, sticky=W)
def load_file(self):
fname = askopenfilename(filetypes=(("Text File", "*.txt"),("All files", "*.*") ))
global globalPath
globalPath = fname
# fname = askopenfilename(filetypes=(("Text File", "*.txt"),("All files", "*.*") ))
if fname:
try:
print("""here it comes: self.settings["template"].set(fname)""")
print (fname)
except: # <- naked except is a bad idea
showerror("Open Source File", "Failed to read file\n'%s'" % fname)
return
if __name__ == "__main__":
MyFrame().mainloop() # All above code will run inside window
print(__name__)
print("the path to the file is : " + globalPath)
2. Watchdog :
from watchdog.observers import Observer
from watchdog.events import PatternMatchingEventHandler
def on_created(event):
# This function is called when a file is created
print(f"hey, {event.src_path} has been created!")
def on_deleted(event):
# This function is called when a file is deleted
print(f"what the f**k! Someone deleted {event.src_path}!")
def on_modified(event):
# This function is called when a file is modified
print(f"hey buddy, {event.src_path} has been modified")
#placeFile() #RUN THE FTP
def on_moved(event):
# This function is called when a file is moved
print(f"ok ok ok, someone moved {event.src_path} to {event.dest_path}")
if __name__ == "__main__":
# Create an event handler
patterns = "*" #watch for only these file types "*" = any file
ignore_patterns = ""
ignore_directories = False
case_sensitive = True
# Define what to do when some change occurs
my_event_handler = PatternMatchingEventHandler(patterns, ignore_patterns, ignore_directories, case_sensitive)
my_event_handler.on_created = on_created
my_event_handler.on_deleted = on_deleted
my_event_handler.on_modified = on_modified
my_event_handler.on_moved = on_moved
# Create an observer
path = "."
go_recursively = False # Will NOT scan sub directories for changes
my_observer = Observer()
my_observer.schedule(my_event_handler, path, recursive=go_recursively)
# Start the observer
my_observer.start()
try:
while True:
time.sleep(1)
except KeyboardInterrupt:
my_observer.stop()
my_observer.join()

Answer 1

Below is the proposed sample code to merge the two scripts (not exactly copy the two scripts into one, but showing the concept of what you request):
from tkinter import *
from tkinter import filedialog
from watchdog.observers import Observer
from watchdog.events import PatternMatchingEventHandler
class Watchdog(PatternMatchingEventHandler, Observer):
def __init__(self, path='.', patterns='*', logfunc=print):
PatternMatchingEventHandler.__init__(self, patterns)
Observer.__init__(self)
self.schedule(self, path=path, recursive=False)
self.log = logfunc
def on_created(self, event):
# This function is called when a file is created
self.log(f"hey, {event.src_path} has been created!")
def on_deleted(self, event):
# This function is called when a file is deleted
self.log(f"what the f**k! Someone deleted {event.src_path}!")
def on_modified(self, event):
# This function is called when a file is modified
self.log(f"hey buddy, {event.src_path} has been modified")
def on_moved(self, event):
# This function is called when a file is moved
self.log(f"ok ok ok, someone moved {event.src_path} to {event.dest_path}")
class GUI:
def __init__(self):
self.watchdog = None
self.watch_path = '.'
self.root = Tk()
self.messagebox = Text(width=80, height=10)
self.messagebox.pack()
frm = Frame(self.root)
Button(frm, text='Browse', command=self.select_path).pack(side=LEFT)
Button(frm, text='Start Watchdog', command=self.start_watchdog).pack(side=RIGHT)
Button(frm, text='Stop Watchdog', command=self.stop_watchdog).pack(side=RIGHT)
frm.pack(fill=X, expand=1)
self.root.mainloop()
def start_watchdog(self):
if self.watchdog is None:
self.watchdog = Watchdog(path=self.watch_path, logfunc=self.log)
self.watchdog.start()
self.log('Watchdog started')
else:
self.log('Watchdog already started')
def stop_watchdog(self):
if self.watchdog:
self.watchdog.stop()
self.watchdog = None
self.log('Watchdog stopped')
else:
self.log('Watchdog is not running')
def select_path(self):
path = filedialog.askdirectory()
if path:
self.watch_path = path
self.log(f'Selected path: {path}')
def log(self, message):
self.messagebox.insert(END, f'{message}\n')
self.messagebox.see(END)
if __name__ == '__main__':
GUI()
