    Exclamation TicTacToe, Qt Desktop, Connecting radio buttons

    Good evening dear Qtccentre.org programmers!

    I am currently in the very early stage of creating tic tac toe game for desktop. I have already created my form, placed buttons on it. But I have no idea how to connect two radiobuttons for my game.
    Here is a screenshot of my game:


    The main idea of it, when users selects the X radio button and clicks to buttons, text "X" should be appear on buttons, and when user select O radio button, text "O" should appear on buttons. I'v tried to use if(rado2->isChecked()) but programm crashes. Please help me to connect this two radiobuttons, so that labels ("X" or "O") could correctly adds to my buttons. Great thanks!

    My code:
    widget.h
    Qt Code: 
    1. #ifndef WIDGET_H
    2. #define WIDGET_H
    3.  
    4. #include <QtGui>

    Default Re: TicTacToe, Qt Desktop, Connecting radio buttons

    I'v tried to use if(rado2->isChecked()) but programm crashes.
    Where did you try to use it?
    Your code is legal, but very cumbersome, and would not be applicable for any real world application.
    Make your self familiar with loops, array/containers.
    For example, instead of:
    Qt Code: 
    1. btn1= new QPushButton;
    2.     btn2= new QPushButton;
    3.     btn3= new QPushButton;
    4.     btn4= new QPushButton;
    5.     btn5= new QPushButton;
    6.     btn6= new QPushButton;
    7.     btn7= new QPushButton;
    8.     btn8= new QPushButton;
    9.     btn9= new QPushButton;
    To copy to clipboard, switch view to plain text mode 
    You can do:
    Qt Code: 
    1. //Where m_vecButtons is declare in the header as: QVector<QPushButton*> m_vecButtons;
    2.   for(int iBtn = 0; iBtn<9; ++i){
    3.     m_vecButtons.push_back(new QPushButton());
    4.   }
    To copy to clipboard, switch view to plain text mode 

    You might also want to have a look at QSignalMapper .

    Do you write clean code? - if you are TDD'ing then maybe, if not, your not writing clean code.
