I don't understand anything you wrote.
Can you post some example code here?

Hey
You can set an icon with one of the QAbstractItem::setData overloaded methods.

Example:

Code:

---

item->setData(QIcon("icon.png"),Qt::DecorationRole);

---

you can see many easy examples in qt assistant....
search for "model/view" topics

Are you able to return text from the model ?
If yes, you must do it with Qt::DisplayRole.
Similary theres Qt::DecorationRole.. thats what caduel said

Code:

---

ui.contentListView->setViewMode(QListView::IconMode);
iStandardModel = new QStandardItemModel(this);
 
QList<QStandardItem*> *items = new QList<QStandardItem*> ();
 
QString qs = ui.searchLineEdit->text();
 
*items = getItemsToDisplay(qs);
 
iStandardModel->appendColumn(*items);
 
//Setting the icon size
ui.contentListView->setIconSize(QSize(128, 128));
//Setting the model
ui.contentListView->setModel(iStandardModel);

In ui_GUIClass.h:

Code:

---

public:
 QListView *contentListView;

---

In GUIClass.h:

Code:

---

public:
 QStandardItemModel* iStandardModel;

---

The result is in attached sample.jpg.
Hope, this helps.
