mouseevent - Catch mouse event on tree widget item in QTreeWidget -

in tree widget have following signal connected:

  connect(mtreewidget, signal(itemclicked(qtreewidgetitem*, int)),           slot(onitemclicked(qtreewidgetitem*, int))); 

where onitemclicked() slot following:

void widgetbox::onitemclicked(qtreewidgetitem *item, int ) {   int index = getpageindex(item);   setcurrentindex(index); }  int widgetbox::getpageindex(qtreewidgetitem *item) {   if (!item) return -1;    qtreewidgetitem *parent = item->parent();   if(parent)  // parent top level item   {     return mtreewidget->indexoftoplevelitem(parent);   }   else        // current item top level   {     return item->treewidget()->indexoftoplevelitem(item);   } }  void widgetbox::setcurrentindex(int index) {   if (index != currentindex() && checkindex(index))   {     mtreewidget->setcurrentitem(mtreewidget->toplevelitem(index));     emit currentindexchanged(index);   } } 

however can't catch itemclicked() signal , onitemclicked() never executed because top level items has push button widget (set setitemwidget() method) intercepts mouse event , child items contain container widgets may have widget combinations in them.

is there method here invoke itemclicked() signal both top level , child items of tree widget?

• installeventfilter() widgets found in item following:
  qlist<qwidget *> widgets = parentwidget.findchildren<qwidget *>();?
• or establish mouse event propagation somehow?
• qcoreapplication::postevent()?

how organize such process better widgets process mouse event need , treewidget issue signal(itemclicked()) well?

so solution simple , following - re-send void itemclicked(qtreewidgetitem *item, int column); signal in pageeventfilter:

pageeventfilter::pageeventfilter(qobject *parent, qtreewidgetitem *item)   : qobject(parent)   , mitem(item) {   connect(this, signal(itemclicked(qtreewidgetitem*,int)),           mitem->treewidget(), signal(itemclicked(qtreewidgetitem*,int))); }  bool pageeventfilter::eventfilter(qobject *obj, qevent *event) {   if (event->type() == qevent::mousebuttonpress)   {     // resend signal qtreewidget     emit itemclicked(mitem, 0);     return false; // send event object (do not filter it)   }   else   {     // standard event processing     return qobject::eventfilter(obj, event);   } } 

p.s. leave previous answer if needs code or idea.
