Hi Mironchik, your example is very helpful. It seems that QListView is just
what I want. I'll take a deeper loop at it. Thank you.

Just to clarification.

Don't forget to setWrapping( true ) on QListView. With such settings 
list view will be displayed as table. And you can play with scroll bars...

QSize sizeHint( const QStyleOptionViewItem &,
const QModelIndex &) const
{
return QSize( 50, 50 );
}
};


int main( int argc, char ** argv )
{
QApplication app( argc, argv );

QListView view;
view.setFlow( QListView::LeftToRight );
view.setResizeMode( QListView::Adjust );
view.setWrapping( true );

Delegate delegate;
view.setItemDelegate(  );


QStringListModel model;
QStringList items;

for( int i = 0; i < 100; ++i )
items.append( QString::number( i ) );

model.setStringList( items );

view.setModel(  );

view.show();

return app.exec();

It's doing this. You can write simple app to check it.

[Interest] Build a Photos(Mac) copy with Qt Widgets

[Hualet Wang]

Hi friends.

I’m trying to build a Photos like application with Qt Widgets. The main view 
should be able to display the photos, delete items on demand. I’m not sure if 
QTableView is sufficient to accomplish the task. Any ideas or any suggested 
project that I can refer to ?

You can do this with QtMWidgets, specifically with AbstractListView.

For example look at this screen-shot:

https://imironchik.blogspot.com/2015/01/qtmwidgetsabstractlistview.html

QtMWidgets you can find here:

https://github.com/igormironchik/qtmwidgets

As I understood you need some kind of table, at this time table is not 
implemented in QtMWidgets, but you can do stuff with list where row will 
display more than one image.


If you are interested I can implement AbstractTableView like 
AbstractListView, I don't think that will take much time from me...

And one more, what about QTableWidget with icons? And why you decided 
that QTableView will not do the trick? I don't have Mac, so I don't know 
what are you talking about exactly...
