How to set minimum height of QListWidgetItem?

Question

How can I set the minimum height of a QListWidgetItem? I'm using QListWidget::setItemWidget() with a customized widget, and although I explicitly declared minimum height of my customized widget, those QListWidgetItems still have a pretty low height attribute.

Answer 1

To set minimum height of each individual QListWidgetItem you can use sizeHint() function. For example, following code will set minimum height of all the QListWidgetItem to 30px..

int count = ui->listWidget->count();
for(int i = 0; i < count; i++)
{
  QListWidgetItem *item = ui->listWidget->item(i);
  item->setSizeHint(QSize(item->sizeHint().width(), 30));
}

Hope this helps..

Answer 2

Use setSizeHint on the items.

void QListWidgetItem::setSizeHint ( const QSize & size )

This is the right method for telling the delegate how much screen it must preserve for the item.
