I am aware that there are commands such as .destroy() , .exit() etc. However, when taking these out of the 'command' from the button parameter of what action to take when pressed, they don't work.
My scenario is when a user logins successfully, the Tkinter window including its widgets should close whilst short after a GUI in pygame opens. I just don't want the Tkinter window to be there once I don't need it ever again whilst also not exiting Python. I don't want a button as I want the process to be automatic.
The thing that baffles me is why when taking out this command to be on its own, it does not work:
Button(root, text="Quit", command=root.destroy).pack() #works
root.destroy() #don't works
Without seeing more of the source code, I guess the problem is based on where you call root.destroy()
If it comes after the blocking tk.mainloop(), it will never be reached. Please read Tkinter understanding mainloop regarding this issue.
A possible solution based on the above:
while True:
tk.update_idletasks()
tk.update()
if login_successful: # or whatever your login check looks like
root.destroy()
You replace the mainloop with your custom loop, which includes a check for a successful login.
