problem with comboBox

[tinysoft]

hi every body

i am facing problem with the combo Box ... i want to change its current value on text edite at line Edit ... so i used this slot :

void CheckoutDialog::on_empNoEdit_textChanged(QString number)
{
 
int i=query.record().indexOf(number);
 
 
        ui->empNameBox->setCurrentIndex(i);
 
}

void CheckoutDialog::on_empNoEdit_textChanged(QString number)
{

int i=query.record().indexOf(number);


        ui->empNameBox->setCurrentIndex(i);

}

To copy to clipboard, switch view to plain text mode 

at execute the combo box do nothing

could any one tel me what i am missing ?

great thanx

i changed the code theory to this one and its worked fine :

void CheckoutDialog::on_empNoEdit_textChanged()
{
 
int k=1;
 
    query.first();
 
    //_______check for item(0)____________
    if (ui->empNoLine->text().toInt()==query.value(0).toInt())
 
       {
            ui->empNameBox->setCurrentIndex(k);
 
 
        }
    //_____________________________________
 
 
    //_______for the rest of items___________
 
   while(query.next())
 
    {
 
 
    if (ui->empNoLine->text().toInt()==query.value(0).toInt())
 
       {
            ui->empNameBox->setCurrentIndex(k);
 
            break;
        }
 
 
    k++;
    }
   //_________________________________________
 
}

void CheckoutDialog::on_empNoEdit_textChanged()
{

int k=1;

    query.first();

    //_______check for item(0)____________
    if (ui->empNoLine->text().toInt()==query.value(0).toInt())

       {
            ui->empNameBox->setCurrentIndex(k);


        }
    //_____________________________________


    //_______for the rest of items___________

   while(query.next())

    {


    if (ui->empNoLine->text().toInt()==query.value(0).toInt())

       {
            ui->empNameBox->setCurrentIndex(k);

            break;
        }


    k++;
    }
   //_________________________________________

}

To copy to clipboard, switch view to plain text mode 

is there any way to do this in a simple way ?

Yes, surely! But You still haven't said what the content of query is, what in your combo box is displayed etc...

One (of some) improvements: use a do-while scope. (or for loop) So you can integrate the check of the first item

[tinysoft]

the query is containing numbers of employees , the combo box containing there names, so i sorted the query by the names alphabet like this :

query.exec("select emp_no from employees  order by name;");

query.exec("select emp_no from employees  order by name;");

To copy to clipboard, switch view to plain text mode 

i want to synchronize the line Edit with the combo box so when user enter number to the line edit , i should get the index of that number on the query and send the index to the combo box to be its current index number.

Instead of alway query the database set the id direct as user data to your combo box. then simply loop through the box and check there. Or if it is a long combo box create a local index hash.
