c++ - Qt set a custom widget inside a QTableView -


i need put custom widget inside qtableview cell subclassed qabstracttablemodel.

i searched given solutions no 1 catch needs. custom widget must stay here time , not in editing mode qitemdelegate::createeditor. custom widget may everything, i'm searching general solutions widget not qpushbuttons or qcheckbox.

sorry english.

you can use qabstractitemview::setindexwidget , overriding qabstractitemview::datachanged achieve want follows:

class mytableview : public qtableview { protected:   void datachanged(const qmodelindex &topleft, const qmodelindex & bottomright, const qvector<int> & roles)   {     qpushbutton *ppushbutton = qobject_cast<qpushbutton*>(indexwidget(topleft));     if (ppushbutton)         ppushbutton->settext(model()->data(topleft, qt::displayrole).tostring());     else         qtableview::datachanged(topleft, bottomright, roles);   } };  void main () {     mytableview table;     table.setcellwidget(table.model()->index(0, 0, qmodelindex()),new qpushbutton()); }

note incomplete implementation, should show how can solve problem. real implementation should update qpushbutton between topleft , bottomright.
