You should reimplement the editorEvent() virtual method from QAbstractItemDelegate. From the documentation:

Mouse events are sent to editorEvent() even if they don’t start editing of the item. This can, for instance, be useful if you wish to open a context menu when the right mouse button is pressed on an item.

So, you can handle mouse events from this method. It is up to you to determine if a click is on an icon or not.

For communication of the event, I would give the delegate one or more signals (that include a QModelIndex as an argument) that communicate the triggering of the event.
