Hi Guys, I want to have an event , if none on the items in the QListWidget are selected.

Becoz in My application, if any one of the ListWidget items has selected then i will be enabling my Delete button like this

void TestDlg::on_TestListWidget_pressed(const QModelIndex &index)
{
ui->deleteBtn->setEnable(true);
}

but this button is keep on enabled , but i want to disable this button , if no items are selected from the QListWidget

QListWidget has itemSelectionChanged(), it’s fired when selection is somehow changed. Just connect to this signal and check, whether something is selected.
