So,I'm making a Tic Tac Toe game and I'd like to put my buttons,like: 3 rows of 3 buttons.
So far I have this:

win = new QWidget;
btn[0] = new QPushButton(this);
btn[1] = new QPushButton(this);
btn[2] = new QPushButton(this);
btn[3] = new QPushButton(this);
btn[4] = new QPushButton(this);
btn[5] = new QPushButton(this);
btn[6] = new QPushButton(this);
btn[7] = new QPushButton(this);
btn[8] = new QPushButton(this);
hl1 = new QHBoxLayout;
hl2 = new QHBoxLayout;
hl3 = new QHBoxLayout;
vl1 = new QVBoxLayout;

hl1->addWidget(btn[0]);
hl1->addWidget(btn[1]);
hl1->addWidget(btn[2]);

hl2->addWidget(btn[3]);
hl2->addWidget(btn[4]);
hl2->addWidget(btn[5]);

hl3->addWidget(btn[6]);
hl3->addWidget(btn[7]);
hl3->addWidget(btn[8]);

vl1->addLayout(hl1);
vl1->addLayout(hl2);
vl1->addLayout(hl3);


win->setLayout(vl1);
TicTacToe::setCentralWidget(win);

But buttons here have the normal size..how can I make then be square?

Thank you.

QButton default Horizontal Policy is Minimum and the Vertical Policy is Fixed. Try to change the sizePolicy property with QSizePolicy::Expanding or whatever you like, for example button->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding)

A QGridLayout might be a good fit for this also.

Yeah,thanks that worked.
But now what I have is a window with buttons all over it(I mean,when I resize window,the layout keeps growing...),but what I want,is to make the buttons on the one side(like make the layout ungrowable!) and some other widgets on the other side,outside the layout...

btn[0]->setGeometry(150,260,150,35);
...
setFixedSize(400, 400);

This doesn't help me...it keeps resizing layout.

Put the other stuff into your layout(s) and adjust the size policies, stretch factors and maximum sizes of the widgets to do sane things with extra space.

U mean,to put the rests widgets to vl1?

Yes, if that is the logical place for them. If not then you might need to nest your existing layout set into another horizontal box layout with more widgets to the right or left of the "grid" you have already.
