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:
Qt Code: 
  1. win = new QWidget;
  2.     btn[0] = new QPushButton(this);
  3.     btn[1] = new QPushButton(this);
  4.     btn[2] = new QPushButton(this);
  5.     btn[3] = new QPushButton(this);
  6.     btn[4] = new QPushButton(this);
  7.     btn[5] = new QPushButton(this);
  8.     btn[6] = new QPushButton(this);
  9.     btn[7] = new QPushButton(this);
  10.     btn[8] = new QPushButton(this);
  11.     hl1 = new QHBoxLayout;
  12.     hl2 = new QHBoxLayout;
  13.     hl3 = new QHBoxLayout;
  14.     vl1 = new QVBoxLayout;
  15.  
  16.     hl1->addWidget(btn[0]);
  17.     hl1->addWidget(btn[1]);
  18.     hl1->addWidget(btn[2]);
  19.  
  20.     hl2->addWidget(btn[3]);
  21.     hl2->addWidget(btn[4]);
  22.     hl2->addWidget(btn[5]);
  23.  
  24.     hl3->addWidget(btn[6]);
  25.     hl3->addWidget(btn[7]);
  26.     hl3->addWidget(btn[8]);
  27.  
  28.     vl1->addLayout(hl1);
  29.     vl1->addLayout(hl2);
  30.     vl1->addLayout(hl3);
  31.  
  32.  
  33.     win->setLayout(vl1);
  34.     TicTacToe::setCentralWidget(win);
To copy to clipboard, switch view to plain text mode 

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

Thank you.
