Actions on selected items from QListWidget when button is clicked

[YouKnowMe]

Hello everybody,

So, I have a QListWidget with some items (item1, item2, item3,...). In the app I want to make that you can select one item, click a button to confirm and then get some result based on the item you selected.
I know how to get indexes of items like this:

int index=ui->mylist->currentRow();

but how to do something when a button(showBtn) is clicked?

You need to create a slot and connect your button's clicked() signal to it.

@sierdzio I did that, but how to pass an index of the selected item and do actions specific to that item?

const auto &selection = ui->myList->selectionModel()->selectedIndexes();
// Or
const auto &selection = ui->myList->selectionModel()->currentIndex();
