<p>A drop shadow effect renders the source with a drop shadow. The color of the drop shadow can be modified using the <a href="qgraphicsdropshadoweffect.html#color-prop">setColor</a>() function. The drop shadow offset can be modified using the <a href="qgraphicsdropshadoweffect.html#offset-prop">setOffset</a>() function and the blur radius of the drop shadow can be changed with the <a href="qgraphicsdropshadoweffect.html#blurRadius-prop">setBlurRadius</a>() function.</p>
<p>By default, the drop shadow is a semi-transparent dark gray (<a href="qcolor.html">QColor</a>(63, 63, 63, 180)) shadow, blurred with a radius of 1 at an offset of 8 pixels towards the lower right.</p>
