tkinter - wm_protocol dosent handle the WM_HELP message
In Tkinter, the wm_protocol
method is used to handle specific window manager protocol messages, such as window closure (WM_DELETE_WINDOW
) or window iconify (WM_TAKE_FOCUS
). However, it does not handle the WM_HELP
message by default.
The WM_HELP
message is typically used for providing context-sensitive help within Windows applications. To handle the WM_HELP
message in Tkinter, you can use the bind
method to bind a function to the event generated by the message.
Here's an example of how you can handle the WM_HELP
message in Tkinter:
pythonimport tkinter as tk
def handle_help(event):
print("Help requested")
root = tk.Tk()
# Bind the <Help> event to the handle_help function
root.bind("<Help>", handle_help)
root.mainloop()
In this example, the handle_help
function will be called whenever the WM_HELP
message is received, triggered by pressing the Help key.
Please note that the availability and behavior of the WM_HELP
message may vary depending on the platform and version of Tkinter you are using. It is recommended to consult the Tkinter documentation and platform-specific documentation for further details on handling specific messages in your application.
