on Button Click decrement the data

[anh5kor]

Hello ,

In code I am trying to implement, that on every button click my data should be reduce.


constructor()
{
connect(ui->pb_uss2ecu_readleft,SIGNAL(clicked()),this,SLOT(Re ad_File_uss2ecuLeft()));
}
somefunction()
{
uss2ecu_count = 144;
}
Read_File_uss2ecuLeft()
{ qDebug()<<"uss2ecu_count_first"<<uss2ecu_count;
uss2ecu_count--;
qDebug()<<"uss2ecu_count_last"<<uss2ecu_count;
}


My output is
First Click
uss2ecu_count_first 144
uss2ecu_count_last 143
second Click
uss2ecu_count_first 189
uss2ecu_count_last 188

That is on every time click it is increasing the data rather than taking old data
My Output should be
First Click
uss2ecu_count_first 144
uss2ecu_count_last 143
second Click
uss2ecu_count_first 143
uss2ecu_count_last 142

You haven't posted real code. You've posted some pseudocode that won't even compile, much less run. How do you expect to get help with a problem when you post something that isn't the problem at all? How can we tell what might be going wrong when all you give us is a few scraps of pseudocode?

Programming is not magic. If the number is changing then something in your program is changing it. Look at all the places in your real code where you assign a value to uss2ecu_count... One of these must be involved. Then work out how you program gets there.
