c++ - Qt How to find out from where the closeEvent(QCloseEvent *event) fired -

i have in main window 2 triggers 1. menu closed totaly app 2. window x button ignored , hide window. i'm using signal/slots how can know beingness triggered?.

in closeevent:

connect(ui->actionquit, signal(triggered()),this, slot(closewin())); void mainwindow::closewin() { close(); } // triggered ui->actionquit amd x button void mainwindow::closeevent(qcloseevent *event) { // how can know bean triggered? hide(); event->ignore(); }

two solutions possible:

connect menu item (qaction) signal separate slot , phone call qapp->quit() there use sender() method within slot determine object sent signal

i prefer first one.

c++ qt

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
