![]() "slots" and "signals " are just another variables. Add the definition to your header and feel free to use it everywhere you want said: Signals don't get implemented in your *.cpp file. In most cases you don't have to change them at all and if you do, there are lambda's or signal overloading, which you dont need to worry about for now.Īnd for custom signals: How should your QtDesigner know, what you are planning to do in order to create them for you? :)Īnd it's just one little line in your header file. The standard Qt signals are just for use only. (Or QtDesigner does not "update " the "signal" code ? "slots " do ! (I personally use this only for my custom QDialogs, to connect buttons to QDialog::reject () or accept())Īre you trying to avoid as much coding work as possible? said in "coding " slots and signals in QtCreator: This is not very helpful, when creating your own programs. A return press inside this QLineEdit will animateClick the OK QPushbutton -> Direct connection, no logic involved, both (signal and slot) are standard Qt slots / signals. Your linked example from Qt doc shows a connection between a QPushButton::clicked signal and, I guess QLineEdit::return but as you've said, you can't "code" or add some logic to these simple connections, that are possible in QtDesigner. I can "push button" and delete widget, but I need to process some real logic. Said in "coding " slots and signals in QtCreator:
