QListWidget::addItem and display immediately

[vlg789]

First of all thanks for the quick answer.

The main reasons why it takes so long to insert items are some operations that take place in background. The listview must keep user informed with the progress, so the problem is not to optimize insertion of items, but to update the listbox immediately.

The only problem i have is that QThread needs a run() and this makes my design more odd... The question is if i can avoid QThread ...

Thanks

One way would be to call QCoreApplication::processEvents() every once in a while to let the application process its events. This will make the overall process a bit longer, though:

// a busy loop
for (...)
{
    // do something
 
    // let the application process its events
    QCoreApplication::processEvents();
}

// a busy loop
for (...)
{
    // do something

    // let the application process its events
    QCoreApplication::processEvents();
}
