tkinter: Disable the focus on each widget-CodePudding

With tkinter you can deactivate the focus of a single widget

tk.Button(root, takefocus=False)

Is it also possible to disable this for all widgets at once?

Edit: By "all" I mean all tk and ttk widgets present in the window.

CodePudding user response：

takefocus is a standard option in tkinter and ttk. So all you have to do is to recursively loop over the widgets and configure them as desired. The function should look like this:

def disable_takefocus(widget):
    for w in widget.winfo_children():
        w.configure(takefocus=False)
        disable_takefocus(w) 
disable_takefocus(root)

Be aware this should be called AFTER you created ALL FINAL widgets. If you dynamically add and delete widgets to your window, it won't help. A general solution for ttk and tkinter does not seem to be possible due the different style engines. For tkinter widgets you could use option_add, but for ttk it is a different animal. Ttk uses a style engine with a fallback chain. It is not easy to spot where the option will be garbed from especially if you take the different themes into account.

For ttk it seems to be the easiest to define styles for each widget.

You can use winfo_children() function to find all children of the window. And you can use configure() function for each child.

from tkinter import *
window=Tk()
btn=Button(window, text="Button1")
btn.place(x=120, y=60)
btn=Button(window, text="Button2")
btn.place(x=120, y=100)
window.title('Disable the focus on each widget')
window.geometry("300x200 10 10")

for child in window.winfo_children():
    child.configure(takefocus=False)
window.mainloop()
