1) I need to set one of my three ttk.Radiobuttons activated by default
when I start my gui app.
How do I do it?
2) I also need to check if one of my ttk.Radiobuttons was
activated/clicked by the user.
How do I do it?
rb1 = ttk.Radiobutton(self.frame, text='5', variable=self.my_var, value=5)
rb2 = ttk.Radiobutton(self.frame, text='10', variable=self.my_var, value=10)
rb3 = ttk.Radiobutton(self.frame, text='15', variable=self.my_var, value=15)
self.rb1.grid(row=0)
self.rb2.grid(row=1)
self.rb3.grid(row=2)
use self.my_var.set(1)
to set the radiobutton with text='5'
as the default RadioButton.
To get the selected one you have to call a function
rb1 = ttk.Radiobutton(self.frame, text='5', variable=self.my_var, value=5,command=self.selected)
rb2 = ttk.Radiobutton(self.frame, text='10', variable=self.my_var, value=10,command=self.selected)
rb3 = ttk.Radiobutton(self.frame, text='15', variable=self.my_var, value=15,command=self.selected)
self.rb1.grid(row=0)
self.rb2.grid(row=1)
self.rb3.grid(row=2)
def selected(self):
if self.my_var.get()==5:
"do something"
elif self.my_var.get()==10:
"do something"
else:
"do something"
