1、3以后尽量手写，因为没有现在的控件了

2、

1   // lyy : 2016/8/26 12:17:41 说明:存放radioButton 2         QButtonGroup *buttonGroup; 3   // lyy : 2016/8/26 11:11:55 说明:radioButton 4     buttonGroup = new QButtonGroup(); 5     buttonGroup->addButton (ui.noSpace_Btn, 0); 6     buttonGroup->addButton (ui.smallSpace_Btn, 1); 7     buttonGroup->addButton (ui.mediumSpace_Btn, 2); 8     buttonGroup->addButton (ui.bigSpace_Btn, 3); 9 10 // lyy : 2016/8/26 14:15:58 说明:用这种方法默认选择与mSelectRadioButton保持一致11     QRadioButton *path = qobject_cast
      
        (buttonGroup->button (mSelectRadioButton));12     path->setChecked (true);13 14   connect (buttonGroup, SIGNAL (buttonClicked (int)), this, SLOT (buttonJudge (int)));
      

3、槽函数

1 void DailyPaper::buttonJudge (int iid)2 {3     quint16 a = buttonGroup->checkedId();4     QMessageBox::information (this, "test", QString::number (a));5     mSelectRadioButton = a;6     //  QMessageBox::information (this, "test1", QString::number (a));7 }
