QListWidget current index/item

naax

Hello guys

I changed ComboBox into QListWidget but I can't resolve this problem.

Before was:
Kcals[0]+=ItemKcals[ItemMap[ui->comboBox->currentText()]];

I tried:
//double Kcals[]
Kcals[0]+=ItemKcals[ItemMap[ui->qListTest->currentIndex()];
Kcals[0]+=ItemKcals[ItemMap[ui->qListTest->currentIndex()];

//mainwindow.cpp:78: error: no viable overloaded operator[] for type 'QMap<QString, int>'

Can you help me with how to read the current Index or Item to this variable Kcals? Before I used QMap and that worked, but I dont have any more ideas.

Hi

QString text;
if (ui->listWidget->currentItem())
   text = ui->listWidget->currentItem()->text();

Do note that currentItem() might be NULL so you must check it or your app will crash.

@mrjj said in QListWidget current index/item:

text = ui->listWidget->currentItem()->text();

That's works! Thanks man!
