create multiple buttons with signal and slots

hi
i want to show multiple pushbuttons in the form dynamically!!! that is the number of pushbuttons i am showing ,will vary at runtime
.So i want to connect each button with signal and slot.i have created a function(i.e slot)
which will be called when any of the button is clicked..

Code:

---

for(int i=0;i<count;i++)
    {
                   QPushButton  *labelbed =new QPushButton(roomgroup);
                     labelbed->setObjectName(bednumbersunderroom.at(i));
 
                        connect(labelbed,SIGNAL(clicked()),signalMapper,SLOT(map()));
                        signalMapper->setMapping(labelbed,labelbed);                                    connect(signalMapper,SIGNAL(mapped(QWidget*)),this,SLOT(onbedclicked(QWidget*)));
    }
void Widget::onbedclicked(QWidget* label)
{
 
 
    QMessageBox *msg=new QMessageBox(this);   
     msg->setText(label->objectName());
    msg->show();
}

when any push button is clicked it displays message box but it displays as many messageboxes as push buttons...
for eg:if there are 3 push buttons,then if i click any one push button it displays 3 messagebox.But it should show only one messagebox..so how to do the signal slots
so that it will show one messagebox for each click!!!

thanks and regards
any help is highly appreciated
:confused::confused::confused:

Code:

---

connect(signalMapper,SIGNAL(mapped(QWidget*)),this,SLOT(onbedclicked(QWidget*)));

must be outside your loop! because then you conntect the signal mapper n-times.

thanks for ur help

hi Lykurg
it works well thanks for ur help
:D:D

place that statement outside of your loop:

Code:

---

connect(signalMapper,SIGNAL(mapped(QWidget*)),this,SLOT(onbedclicked(QWidget*)));

Lykurg has already indicated that in 3 post ;)

Of course he has; when I replied that answer was not there for me to see. (Otherwise I would not have posted anymore.)
Happens now and then. Sorry (not my fault, though).
