Buttons (QPushButton) can be added to any window. The QPushButton class has the method setText() for its label and move(x,y) for the position.

In this article you can see how a button can be added to a window, and how you can connect methods to it.

PyQt Button Example

Signals and slots

You can create a button with a few lines of code:

1
2
3
button1 = QPushButton(widget)
button1.setText("Button1")
button1.move(64,32)

Then connect it to a method with:

1
button1.clicked.connect(button1_clicked)

The receiving method is called a slot, the clicked.connect (if the button is clicked) is called a signal.

def button1_clicked():
   print("Button 1 clicked")
