How do I create a custom slot in qt4 designer?

Question

Whenever I use the signal/slot editor dialog box, I have to choose from the existing list of slots. So the question is how do I create a custom named slot?

Answer 1

I am able to do it by:

In MainWindow.h, add the line:

public slots:
     void example();

in the MainWindow class.

In MainWindow.cpp

void MainWindow::example() {
     
}
