Your suggestions have been taken in count. Now the code has been adapted to the arrows direction, and a cool effect has been introduced: animating when collapsing or expanding a title. Well it is just adding the line <code>
d-&gt;treeView-&gt;setAnimated<span style="color: rgb(0, 0, 0);">(</span><span style="color: rgb(0, 0, 255);">true</span><span style="color: rgb(0, 0, 0);">) </span></code>but is more cool than before.<br><br>You can go to
