}myClass::myClass(QWidget *parent)
: QMainWindow(parent)
{
ui.setupUi(this);listWidget1 = new QListWidget; // listWidget1 declared in *.h file as pulic type
listWidget1->setObjectName(QStringLiteral("listWidget1"));
listWidget1->setGeometry(QRect(550, 290, 256, 111));
bool bc = connect(listWidget1, SIGNAL(ItemDoubleClicked(QListWidgetItem *)), this, SLOT(myItemDoubleClicked(QListWidgetItem *)));
}void Myclass::myItemDoubleClicked(QListWidgetItem *item){
int i;

@hitbuyi said in DoubleClick not work when double click QListWidget item:
ItemDoubleClicked
This is wrong, correct signal name is itemDoubleClicked.
To avoid such problems you should use new Qt5 connect syntax. -
