Hi list,
In my code there is a bunch of calls which try to create QIcons from
QStyle standard pixmaps, like:
QIcon groupIcon;
groupIcon.addPixmap( style()->standardPixmap( QStyle::SP_DirClosedIcon ),
QIcon::Normal, QIcon::Off );
groupIcon.addPixmap( style()->standardPixmap( QStyle::SP_DirOpenIcon ),
QIcon::Normal, QIcon::On );
While this works correctly, in that using the icon for a model's
DecorationRole shows either an open or closed icon based on the item's
expanded state, it has two issues:
1. It's not hi-dpi friendly, and the icons are tiny
2. QStyle::standardPixmap is marked as obsolete, with
QStyle::standardIcon being described as the preferred approach.
I'm unsure how to translate the above code to QStyle::standardIcon though.
QIcon groupIcon( style()->standardIcon( QStyle::SP_DirClosedIcon ) );
works nicely for closed items, and looks great on hidpi. But I can't
see how I would add the SP_DirOpenIcon state. There's no equivalent
method like "QIcon::addIcon" like there is QIcon::addPixmap.
What's the correct approach to take here, which is hi-dpi friendly and
future proof?
Cheers,
Nyall
