Syntax for QspinBox connection

For QPushButton named "pushButtonShow" we can create a slot with this syntax and we do not need to explicitly create the connect expression

void on_pushButtonShow_clicked();

what would be the similar syntax for QSpinBox

Solution 1:

When designing Qt Widget forms I recommend you to use Qt Form editor in Qt Designer or Qt Creator. In this editor you can simply right click the selected object, open context menu and choose Go to slot, that will create C++ slot in your selected form class.

Alternatively, the syntax is always the same, put in slots following

void on_<objectName>_<signalName>(<signal arguments>);
