How to change the size of the item clicked on in a Q3DScatter?

[quackinsh]

Hello everyone

I have a QWidget application in which i load a a 3D scatter graph. Per default, it is possible to click on points of the graph and these points are then highligted somehow (i.e. change it's color). I would like to change and customize the behavior when one clicks on a point.
I already can change the color, using the setSingleHighlightColor of QAbstract3DSeries Class. But I would also like to change the size of the selected item. I only know a method to increase the size of a hole series, using "setItemSize". But I would like to only set the itemSize for the current selected item.

How it that possible? I would like to avoid using a custom input handler.

Thanks in advance!
