how to check the output of the QCombobox box

milhao

hi, I'm trying to compare the player's choice return in the QComboBox box to create different actions, how do I check the output of the QComboBox?

I assume you drag and drop a comboBox in you're ui.file and then set the items, if this is you're case you can try :

-Go to the ui.file , right click on the comboBox , GoToSlot -> select on CurrentTextChanged, then , in the method that is created automathically you write this:

void MainWindow::on_comboBox_1_currentTextChanged(const QString &arg1)
{
    if(ui->comboBox_1->currentText()=="elf"){
        qDebug()<<" you have chosen  --> "<<ui->comboBox_1->currentText();
 }else if(ui->comboBox_1->currentText()=="human"){
        qDebug()<<" you have chosen --> "<<ui->comboBox_1->currentText();
    }
}

@milhao
QComboBox::currentIndex() or QComboBox::currentText().
Corresponding ...Changed() signals if you want them.

@JonB how would I use this corresponding Changed() signal.
And another one, what is the return of QComboBox::currentIndex() or QComboBox::currentText(), because I want to get the word elf and compare it with the return of QComboBox to know if it is chosen

Check this for QComboBox properties and this for connecting signals/slots.
