</code></pre></div>
<p>Test it out by using the <code class="language-unknown">QT_STYLE_OVERRIDE</code> environment variable when executing the program</p>
<div class="remark-highlight"><pre class="language-bash"><code class="language-bash"><span class="token assign-left variable">QT_STYLE_OVERRIDE</span><span class="token operator">=</span>Adwaita-Dark designer

<div class="remark-highlight"><pre class="language-bash"><code class="language-bash"><span class="token builtin class-name">echo</span> <span class="token string">"export QT_STYLE_OVERRIDE=Adwaita-Dark"</span> <span class="token operator">>></span> ~/.profile
