QListWidget set item spacing dynamically based on font's height

I would like to set item spacing based on QListWidget's font's size. How can I do that ?

solved by subclassing QItemDelegate and overriding sizehint- function:

.cpp

Code:

---

#include "mylistdelegate.h"
#include <QDebug>
 
MyListDelegate::MyListDelegate(QObject *parent) :
    QItemDelegate(parent)
{
}
 
QSize MyListDelegate::sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const
{    
    QFontMetrics fm(option.font);
    QRect rect;
 
    QSize sz=QItemDelegate::sizeHint(option, index);
    sz.setHeight(fm.height()*1.5);
 
    return sz;
}

---

.h

Code:

---

#include <QStyledItemDelegate>
#include <QItemDelegate>
 
class MyListDelegate : public QItemDelegate
{
    Q_OBJECT
public:
    explicit MyListDelegate(QObject *parent = 0);
    virtual QSize sizeHint ( const QStyleOptionViewItem & option, const QModelIndex & index ) const;
 
 
 
};
