i tried to use tkinter for my yt downloader but now im facing this problem ( freezing ) i searched for the fix of it and found threading and tried it works fine when pressing button but can't even download any video when running it
error from pytube :
regex_search: could not find match for (?:v=|\/)([0-9A-Za-z_-]{11}).*
The actual thing happening here is, threading working on the button, then it somehow executes the code without even adding a URL and then the program stop working even if i tried to put a URL and download it. any ideas??
CodePudding user response：
Your command callback for the self.download is being fired right away during the construction of your GUI.
You should wrap it in a lambda so that it is only executed when the button is clicked.
self.download = customtkinter.CTkButton(self, text="Download", command=lambda: threading.Thread(target=self.download_event).start())
