How to access an object inside a privateslot

[graciano]

This is more what i had in mind but now i need to ask a final question.
In line 39 i used the int 1 (one) just to test it.
Is there a way to return the index position in the string list (an integer) to use in there?

ufff ... solved it like this:

void IdDoAutomovelDialog::on_lineEdit_textChanged(){
    okButton->setEnabled(lineEdit->hasAcceptableInput());
 
    //Limpar chapa
    labelDescSerie->setText("?");
 
    //Verificar qual a série de matrÃ*cula
    QLineEdit newlineEdit;
    newlineEdit.setText(lineEdit->text());
 
    QRegExp serie;
    serie.setPattern("");
    QRegExpValidator validator(serie,this);
    newlineEdit.setValidator(&validator);
    for ( QStringList::Iterator it = listaMatriculasValidas.begin(); it != listaMatriculasValidas.end();++it ){
        serie.setPattern(*it);
        validator.setRegExp(serie);
        if(newlineEdit.hasAcceptableInput()){
            switch(listaMatriculasValidas.indexOf(serie.pattern(),0)+1){
                case 1: labelDescSerie->setText("Chapa de modelo anterior a 1992");
                        break;
                case 2: labelDescSerie->setText("Chapa de modelo utilizado entre 1992 e 2005");
                        break;
                case 3: labelDescSerie->setText("Chapa de modelo posterior a 2005");
                        break;
                default:labelDescSerie->setNum(listaMatriculasValidas.indexOf(serie.pattern(),0));
            }
        }
    }
}

void IdDoAutomovelDialog::on_lineEdit_textChanged(){
    okButton->setEnabled(lineEdit->hasAcceptableInput());

    //Limpar chapa
    labelDescSerie->setText("?");

    //Verificar qual a série de matrÃ*cula
    QLineEdit newlineEdit;
    newlineEdit.setText(lineEdit->text());

    QRegExp serie;
    serie.setPattern("");
    QRegExpValidator validator(serie,this);
    newlineEdit.setValidator(&validator);
    for ( QStringList::Iterator it = listaMatriculasValidas.begin(); it != listaMatriculasValidas.end();++it ){
        serie.setPattern(*it);
        validator.setRegExp(serie);
        if(newlineEdit.hasAcceptableInput()){
            switch(listaMatriculasValidas.indexOf(serie.pattern(),0)+1){
                case 1: labelDescSerie->setText("Chapa de modelo anterior a 1992");
                        break;
                case 2: labelDescSerie->setText("Chapa de modelo utilizado entre 1992 e 2005");
                        break;
                case 3: labelDescSerie->setText("Chapa de modelo posterior a 2005");
                        break;
                default:labelDescSerie->setNum(listaMatriculasValidas.indexOf(serie.pattern(),0));
            }
        }
    }
}

Make it an input parameter of your slot. Then do your switch(ipIndex).

[jpn]

Something I don't get is that a slot connected to QLineEdit::textChanged() creates another QLineEdit every time the text of the former line edit changes.

[graciano]

The original QLineEdit contains something like:
"egexp1"<<"|"<<""regexp"<<"|"<<"egexp3"<<...<<"reg expn"
This way i can validade entries that satisfy regexp1 or regexp2 or ....

Inside the slot the newLineEdit is used to validate a specific regexp(i) so that i can use it to obtain an index in the string list.

Perhaps it is not the cleanest aproach but it is working.

If you want to take a look and comment it i would apreciate:
