QT 复选框实现互斥功能，单选框与复选框之间转换

场景需求如下:当选择单关节单自由度，右边只能单选；当选择单关节多自由度，右边可以复选。但是只能选择相同关节的不同自由度，也就是只能选择1，2或3，4或5，6；当选择多关节多自由度时，右边就是正常的复选按钮。

实现： 

左边3个为QRadioButton单选框，右边6个为QCheckBox复选框。

negativemode.h头文件中加入：

private slots:
void switchFXorDX(bool flag);//左边单选框的槽函数
void gj_select(bool flag);//右边复选框的槽函数

private:
static int a;

negativemode.cpp源文件中加入：

groupButton2=new QButtonGroup(this);

//将单选框/复选框与槽函数关联
connect(singlesingle,SIGNAL(toggled(bool)),this,SLOT(switchFXorDX(bool)));
connect(singlemulti,SIGNAL(toggled(bool)),this,SLOT(switchFXorDX(bool)));
connect(multimulti,SIGNAL(toggled(bool)),this,SLOT(switchFXorDX(bool)));

connect(jnw,SIGNAL(toggled(bool)),this,SLOT(gj_select(bool)));
connect(jqs,SIGNAL(toggled(bool)),this,SLOT(gj_select(bool)));
connect(zqs,SIGNAL(toggled(bool)),this,SLOT(gj_select(bool)));
connect(bqh,SIGNAL(toggled(bool)),this,SLOT(gj_select(bool)));
connect(wrp,SIGNAL(toggled(bool)),this,SLOT(gj_select(bool)));
connect(wnw,SIGNAL(toggled(bool)),this,SLOT(gj_select(bool)));


int negativemode::a=0;
void negativemode::switchFXorDX(bool flag)
{
    QRadioButton *select=qobject_cast<QRadioButton*>(sender()); //得到当前信号来源的对象
    if (flag==true&&select==singlesingle){//选中singlesingle：单关节单自由度
        a=1;
        groupButton2->addButton(jnw,0);
