QT Learning Solution qlistwidgetitem overlap, point to all selected issues

Qlistwidget in Qlistview::iconmode mode, when the entry can be moved, if some or all overlap occurs, then clicking on one of the Qlistwidgetitem will also check the overlapping qlistwidgetitem, the problem is as follows:

But I just want to choose the one I clicked on, solve this problem, didn't find a good way. To process by inheriting the Mousepressevent event:

void Listwidget::mousepressevent (Qmouseevent *event) {__super::mousepressevent (event); Qlistwidgetitem *pitem = Itemat (Event->pos ()), if (pitem) {int iCount = count (); for (size_t i = 0; i < ICount; i++) {QL Istwidgetitem *p = Item (i), if (!p) break;if (P! = Pitem) p->setselected (false); elsep->setselected (True);}}

or:

void Listwidget::mousepressevent (Qmouseevent *event) {__super::mousepressevent (event); Qlistwidgetitem *pitem = Itemat (Event->pos ()), if (pitem) {qlist<qlistwidgetitem *> pitems = SelectedItems (); for (Auto it = Pitems.begin (); It! = Pitems.end (); it++) {if (*it)! = Pitem) (*it)->setselected (false); else (*it)->se Tselected (True);}}}

can meet the requirements. If someone has a better way, please instruct.
