Multiple images in a ttk label widget
<p>With ttk labels, it is possible to specify multiple images which are displayed according to the label's state. But I can't make it work. Here is the code.</p>

</code></pre>

<p>The label is 'active' when the mouse pass over it. So the displayed digit should switch from a 0 to a 1 when the mouse passe over it. But it doesn't work.
Any help ?

<p>I find the docs a bit confusing but it looks like you want <code>'hover'</code> instead of <code>'active'</code>.</p>

<p>I am not aware of any source explaining which state flags are automatically set in which wigdets in which conditions. What I did here was to place the mouse cursor over the label and then query the state by calling <code>label.state()</code>.</p>
