How can you design a button to load to a new panel

Hi,

I was wondering how you can maybe design a function that you can use to plug into a button definition that allows you to load into a new panel when the button is clicked. Thanks!

tutorial workshop 6 is about buttons, that should help

I have went through, it doesn't help on the way to get a panel in a button clicked function.

whats about mouse_panel?

Don't you have to make a function defining what that command does though? I had I create a function defining quit_program means to exit and another to load a level when clicking start
