Many PushButton
-
Hello, how can i to make this easier and shorter?
I have many PushButton (more then 100) and doing similar thing.public slots:
@
void MyForm::on_pb_1_clicked() { Methode(pb_1, Array[0]);}
void MyForm::on_pb_2_clicked() { Methode(pb_2, Array[1]);}
.
.
.
void MyForm::on_pb_n_clicked() { Methode(pb_n, Array[n-1]);}
@pb_1, .... pb_n is many pushbutton.
Edit: please use code tags, Andre

QSignalMapper!

Example:
@
QSignalMapper *btnGroup;
btnGroup = new QSignalMapper(this);
connect(btnGroup, SIGNAL(mapped(int)), this, SIGNAL(btnOutClickSlot(int)));void myclass::btnOutClickSlot(int btn)
{
//code here
}QPushButton *tmp[2] = {pushButton,pushButton_2};
for (quint16 i = 0; i < 2; i++)
{
btnGroup->setMapping(pushB[i], i);
connect(tmp[i], SIGNAL(clicked()), btnGroup, SLOT(map()));
}

You can use sender() inside slots to find out who sent the signal.
@
void MyForm::on_pb_any_clicked()
{
if(sender() == pb_1)
Methode(pb_1, Array[0]);
if(sender() == pb_2)
Methode(pb_2, Array[0]);
.....
......
}

I highly recommend using QSignalMapper instead of using sender().

QSignalMapper is a perfect solution. TY!

It's a perfect solution except figuring out how to use it.
