Question

I have StackedWidget with 3 pages, every page contain 3 lineEdit, now at every page I pass, I want to save the content of this 3 lineEdit into a variable to be able later handle it.
I have this piece of code:

connect(ui->stackedWidget, SIGNAL(currentChanged(int)), this, SLOT(getInputs(int)));

And the slot:

void ConfSetup::getInputs(int index)
{
    QString para;

    switch(index)
     {
        case 1:
            ui->backButton0->setEnabled(false);
        break;

        case 2:
            inputs << ui->serverEdit->text();
            inputs << ui->portEdit->text();
        break;

        case 3:
            inputs << ui->userDbEdit->text();
            inputs << ui->passwordDbEdit->text();
        break;

        case 6:
            foreach(para, inputs)
               ui->comboBox->addItem(para);
            //ui->lineEdit->setText(QString::number(para.length()));
        break;

        default:
            ui->backButton0->setEnabled(true);
        break;
     }
}

The comboBox widget should now contains 4 values, but rather then it contains a blank text, also para.length() return 0 in lineEdit widget.

Answer 1

A friend tell me that I am filling the inputs variable at time I change the index page, witch mean of course the lineEdit widgets are empty at that time. The solution is very simple, first, I avoid getInputs(int ) slot, and in replacement I make this:

ui->comboBox->addItem(ui->serverEdit->text());
ui->comboBox->addItem(ui->portEdit->text());
ui->comboBox->addItem(ui->userDbEdit->text());
// ... etc
