<p>Currently i have a scenario where buttons are disabled.Now i want to enable the buttons when some input is entered by the user in tkinter entry widget.</p>

<p>Please suggest.</p>

<p>Thanks!</p>

<p>You can <code>bind()</code> function to <code>Entry</code> which will be executed when user press <code>&lt;Key&gt;</code>.</p>

<p>See <code>bind()</code> and <code>&lt;Key&gt;</code> in <a href="http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm" rel="nofollow">Events and Binding</a></p>
