I need to change the state from DISABLED
to NORMAL
of a Button
when some event occurs.
Here is the current state of my Button, which is currently disabled:
self.x = Button(self.dialog, text="Download",
state=DISABLED, command=self.download).pack(side=LEFT)
self.x(state=NORMAL) # this does not seem to work
Can anyonne help me on how to do that?
This is what worked for me. I am not sure why the syntax is different, But it was extremely frustrating trying every combination of activate, inactive, deactivated, disabled, etc. In lower case upper case in quotes out of quotes in brackets out of brackets etc. Well, here's the winning combination for me, for some reason.. different than everyone else?
import tkinter
class App(object):
def __init__(self):
self.tree = None
self._setup_widgets()
def _setup_widgets(self):
butts = tkinter.Button(text = "add line", state="disabled")
butts.grid()
def main():
root = tkinter.Tk()
app = App()
root.mainloop()
if __name__ == "__main__":
main()
I think a quick way to change the options of a widget is using the configure
method.
In your case, it would look like this:
self.x.configure(state=NORMAL)
