<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">As this was rejected from QIcon, I decided to implement it in frameworks. The idea is new private icon engine (KOverlayIconEngine), which paints the overlays itself, and then an utility function in KIconUtils:: namespace, which takes the base icon and the overlay icons as parameters and constructs new QIcon using KOverlayIconEngine. As QPixmapIconEngine (QIcon default) is private in Qt and couldn't be simply extended, the KOverlayIconEngine simply forwards the calls to QIcon, which then forwards those calls internally to QPixmapIconEngine (QIcon is really mostly just a wrapper around an engine).
There are two functions
QIcon KIconUtils::kIconAddOverlay(const QIcon &icon, const QIcon &overlay, Qt::Corner position);
and
QIcon KIconUtils::kIconAddOverlay(const QIcon &icon, QHash<Qt::Corner, QIcon> overlays);
The first one serves for single overlay icon, the second one is then for multiple overlays, requires the QHash to be built up before passing though.</pre>
