QTreeWidget Signal and slot

darkstaring

Hi... after populated my QTreeWidget
at the end, i write this:

connect(ui->treeWidgetWiFis,SIGNAL(itemClicked(QTreeWidgetItem *,int)),this,SLOT(apri_connessione(QTreeWidgetItem*)));

and

void MainWindow::apri_connessione(QTreeWidgetItem *item)
{
    qDebug()<<item;
}

but i have error,
then i added in MainWindow.h, in private slot:

void apri_connessione();

but not resolve.... this is the error...
error: out-of-line definition of 'apri_connessione' does not match any declaration in 'MainWindow'...

Any help ?

Thank you...

Yes, it doesn't match with function signature. apri_connessione(QTreeWidgetItem*) and you have added void apri_connessione();

darkstaring

How to fix ?

EDIT:

if in design make right click in QTreeWidget -> go to slot -> itemClicked()
not work!
with
error: ‘QTreeWidgetItem’ has not been declared
void on_treeWidgetWiFis_itemClicked(QTreeWidgetItem *item, int column);
^~~~~~~~~~~~~~~
