Compilation errors after deleting/editing UI widgets. Tried everything

? Offline

First of all, I tried everything that helped others with the same problem. Deleting the build directory, cleaning the build and running qmake, disabling Shadow-Builds, and so on.. But the moc_mainwindow.cpp doesn't cease to contain references to non-existent widgets.

the one I deleted:

C:\Users\sophie\Documents\Bestellungen\debug\moc_mainwindow.cpp:112: Fehler: undefined reference to `MainWindow::on_checkBox_toggled(bool)'

the one I renamed:

C:\Users\sophie\Documents\Bestellungen\debug\moc_mainwindow.cpp:113: Fehler: undefined reference to `MainWindow::on_pushButton_clicked()'

any idea? :(

@SnuggleKat Do you maybe still have connections for these slots somewhere?

hi @SnuggleKat

please do not rely on the automatic connect by name method that Qt and QtDesigner provide.
That will and does, like you just now detected, break very easily.

I recommend connecting all your signals to slots by hand, and using the new Qt5 Syntax
https://wiki.qt.io/New_Signal_Slot_Syntax

delete your build folder and rerun qmake, it will fix your issue.

@jsulm @J-Hilk
Yes I had.. I have totally forgotten to remove the slots from my header file (feels ashamed).
thanks for the reminder :)

@SnuggleKat No problem, happens sometimes :-)
