Hi and welcome to devnet,

Your QStackedWidget is named "pages" and you should use that object to switch between the widgets inside them.

[Marek Bilinski]

@SGaist So i changed the name of in the code to pages, but still dont know how i should connect button with this command

[SGaist]

Might be a silly question but are you sure you are clicking the button you connected ?

[Marek Bilinski]

@SGaist Okay, i found my mistake, thanks for help!
