Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

The error message, minus the name, is 'cannot call member function ... without object'. That means you are attempting to call a non-static member function without an object.

This simply duplicates and justifies (?) the error message. OK , but I am looking for a solution.

The task is to pass an "item" between list and list_2 - the methods itemClicked parameter should be "item" , by same token the addItem method should have "item" parameter passed. Without parameters the compiler reject the whole "connect" function as "unknown".

/media/f/QT/Qt/QT/qtconnectivity/examples/bluetooth/CAT_BT_18112020/device.cpp:127: error: no matching function for call to 'DeviceDiscoveryDialog::connect(QListWidget*&, void (QListWidget::*)(QListWidgetItem*), QListWidget*&, <unresolved overloaded="" function="" type="">)'
);
