<DIV id=read_tpc mb10?>两个QRadioButton按钮在同一个widget上面，当一个QRadioButton 按下时另一个QRadioButton 也跟着按下。
我们假设第一个按钮是a,第二个是b，槽函数myslot（）是将b置为按下的语句。
那么connect(a,SIGNAL(clicked()), ??, SLOT(myslot()))中？？的位置应该是什么才能保证按下a后b也跟着变

如果两个radiobutton都是这个类的成员，myslot也是这个类的成员函数，？？应该是this啊！

this的话会出段错误

问题解决没有？

没有

先不管那个 多个QRadioButton按钮如果在同一界面，只能且最多选一个。所以你用QButtonGroup分开这两个QRadioButton按钮。
this段出错，贴下connect语句所在的函数。

#include "main.h"

        QButtonGroup *zu1 = new QButtonGroup(this);

        zu1->addButton(r1, 0);
        zu1->addButton(r2, 1);
        zu1->addButton(r3, 2);
        zu1->addButton(r4, 3);
        zu1->addButton(r5, 4);
        zu1->addButton(r6, 5);
        zu1->addButton(r7, 6);
        zu1->addButton(r8, 7);

        QButtonGroup *zu2 = new QButtonGroup(this);


        zu2->addButton(c1, 0);
        zu2->addButton(c2, 1);
        zu2->addButton(c3, 2);
        zu2->addButton(c4, 3);
        zu2->addButton(c5, 4);
        zu2->addButton(c6, 5);
        zu2->addButton(c7, 6);
        zu2->addButton(c8, 7);

        connect(c1, SIGNAL(clicked()), this, SLOT(myslot()));
void MyWidget::myslot()
{
    r1->setCheckable(true);
    r1->setChecked(true);
    r1->setAutoRepeat(true);
    r1->setAutoExclusive(true);
}

connect语句还提示段出错吗 mySlot函数为什么那样写？

信号跟槽连接  要带参数的啊  把参数带上试试

connect(c1, SIGNAL(clicked(bool)), this, SLOT(myslot(bool)));
void MyWidget::myslot(bool checked)
{
    r1->setCheckable(true);
    r1->setChecked(true);
    r1->setAutoRepeat(true);
    r1->setAutoExclusive(true);
}
