Answer 1

In the constructor of the main widget, we create some kind of layout:
We push our button into it:
and set it as the current one:
setLayout(l);

>does kavoto have the source code for the Minesweeper game?
My soul has no rest,
All day long I've been waiting for Cavoto
I meet the dawn without sleep,
And all because of Cavoto Cavoto
is not with me
Oh, where can I find Cavoto?
I can go around the whole world,
To find Kavoto...
To find Kavoto,
I can go around the whole world.
Sorry I couldn't resist.
PS I propose to start a #homework tag on the toaster, where experienced programmers will solve problems day and night for the younger generation of idlers.
