Sorry, the list is still experimental, so we have no useful
documentation in the manual :-(

Yes, at the moment we only support widget rendering, so I can explain
this one. To configure the height for the the image you have to change
the default size for the row first:
list.setItemHeight(50);
Now the row has the default size from 50 pixel, but at the moment the
used widget for item rendering doesn't support auto sizing, so it is
important also to configure the widget. To configere a widget, we can
use the same principle like with Data Binding, we use a delegate for
this job:
list.setDelegate({
configureItem : function(item) {
item.getChildControl("icon").setWidth(48);
item.getChildControl("icon").setHeight(48);
item.getChildControl("icon").setScale(true);
});
The passed item is by default a qx.ui.form.ListItem so you can use the
API to configure your needs.
If you have further questions, please ask.
Cheers,
Chris
