Size of an Icon

[LordQt]

Hello Friends.
How can I modify the size of my icon in my QListWidgetItem. I have an png with 128*128

QStringList myStringList2;
	myStringList2 <<"test";
	QIcon testItemIcon(":/images/undo.png");
	foreach(QString str2, myStringList2){
		QListWidgetItem *testItem = new QListWidgetItem(testItemIcon, str2, customerList);
		customerList->addItem(testItem);
		QRadialGradient gradient(100, 100, 100, 100, 100);
   		gradient.setColorAt(0, QColor::fromRgbF(210, 239, 109,0));
   		gradient.setColorAt(1, QColor::fromRgbF(0, 1, 0, 0)); 
   		QBrush brush(gradient);
		testItem->setBackground(brush);
	}

QStringList myStringList2;
	myStringList2 <<"test";
	QIcon testItemIcon(":/images/undo.png");
	foreach(QString str2, myStringList2){
		QListWidgetItem *testItem = new QListWidgetItem(testItemIcon, str2, customerList);
		customerList->addItem(testItem);
		QRadialGradient gradient(100, 100, 100, 100, 100);
   		gradient.setColorAt(0, QColor::fromRgbF(210, 239, 109,0));
   		gradient.setColorAt(1, QColor::fromRgbF(0, 1, 0, 0)); 
   		QBrush brush(gradient);
		testItem->setBackground(brush);
	}

QListWidget is a QListView. QListView is a QAbstractItemView. QAbstractItemView has a property iconSize:

listWidget->setIconSize(QSize(24, 24));

listWidget->setIconSize(QSize(24, 24));

I don´t understand i don´t have a listWidget i have a ListWidgetItem

and QListWidgetItem have no setIconSize()

QAbstractItemView is the base class of QListWidget and it has that method.

QListWidget is a widget where QListWidgetItems are added to. QListWidgetItems are nothing visible until they are added to a QListWidget.

So what is customerList?

customerList->addItem(testItem);

customerList->addItem(testItem);

QListWidgetItem *testItem = new QListWidgetItem(testItemIcon, str2, customerList);
customerList->addItem(testItem);

QListWidgetItem *testItem = new QListWidgetItem(testItemIcon, str2, customerList);
customerList->addItem(testItem);

Hi,
only a little note: it is not needed to use addItem() if you already specified the parent QListWidget in the QListWidgetItem constructor.
It is not an error, but it is redundant.

These are a little better ways to do it:

// Constructed with the list widget as their parent widget
QListWidgetItem *testItem = new QListWidgetItem(testItemIcon, str2, customerList);

// Constructed with the list widget as their parent widget
QListWidgetItem *testItem = new QListWidgetItem(testItemIcon, str2, customerList);

To copy to clipboard, switch view to plain text mode 

// Constructed with no parent widget and added to the list later
QListWidgetItem *testItem = new QListWidgetItem(testItemIcon, str2);
customerList->addItem(testItem);

// Constructed with no parent widget and added to the list later
QListWidgetItem *testItem = new QListWidgetItem(testItemIcon, str2);
customerList->addItem(testItem);
