QListWidgetItem* item = new QListWidgetItem("Item 1"); item->setSizeHint(QSize(100, 100));
QListWidget* listWidget = new QListWidget(); listWidget->setIconSize(QSize(64, 64)); QListWidgetItem* item1 = new QListWidgetItem("Item 1"); item1->setSizeHint(QSize(150, 150)); QListWidgetItem* item2 = new QListWidgetItem("Item 2"); item2->setSizeHint(QSize(200, 200)); listWidget->addItem(item1); listWidget->addItem(item2);In this example, we create a new QListWidget and set its icon size to 64x64 pixels. We then create two QListWidgetItem objects and set their size hints to 150x150 and 200x200 pixels, respectively. Finally, we add both items to the list widget. Package/Library: Qt Widgets Overall, QListWidgetItem is a useful class for creating and managing items in a QListWidget. The SetSizeHint function is particularly helpful for controlling the size and layout of list widget items.
