    <p>Use the <b>thumbSize</b> <glossary tag="property">property</glossary> to specify the size of a <glossary tag="scrollbar">scrollbar's</glossary> draggable <glossary tag="scrollbar thumb">thumb</glossary>.</p><p/><p><b>Value:</b></p><p>The <i>number</i> is a number between the <glossary tag="scrollbar">scrollbar's</glossary> <property tag="startValue">startValue</property> and <property tag="endValue">endValue</property>.</p><p/><p><b>Comments:</b></p><p>Normally, the <b>thumbSize</b> is proportional to the proportion of content visible on the screen. For example, if a third of the content can be seen and the rest is always scrolled off, the <glossary tag="scrollbar thumb">scrollbar thumb</glossary> should cover a third of the scrollbar area, so the <i>number</i> should be one-third of the difference between the <glossary tag="scrollbar">scrollbar's</glossary> <property tag="startValue">startValue</property> and its <property tag="endValue">endValue</property>.</p><p/><p>If the <b>proportionalThumbs</b> <glossary tag="property">property</glossary> is set to false, this <glossary tag="property">property</glossary> has no effect.</p>
