<p>Sets a new style for <em class="parameter"><code>gso</code></em>
, and emits "style-changed" signal. This function
does not take ownership of <em class="parameter"><code>style</code></em>
.</p>
<p>The best way to change the style is to set the "style" property.</p>
<p>This function will fail if the new style and the previous style are the same.
In that case, the function will always return false:</p>

<p>In this sample, the call to <a class="link" href="GOStyledObject.html#go-styled-object-set-style" title="go_styled_object_set_style ()"><code class="function">go_styled_object_set_style()</code></a> is just useless. You
need to check yourself if you really change the size, call
<a class="link" href="GOStyledObject.html#go-styled-object-style-changed" title="go_styled_object_style_changed ()"><code class="function">go_styled_object_style_changed()</code></a> to trigger the "style-changed" event.
