--- Comment #3 from Laurent Montel <mon...@kde.org> ---
When I read qt code I see that icon is caching
QIcon QIcon::fromTheme(const QString &name, const QIcon &fallback)
{
QIcon icon;
if (qtIconCache()->contains(name)) {
icon = *qtIconCache()->object(name);
} else {
QPlatformTheme * const platformTheme =
QGuiApplicationPrivate::platformTheme();
QIconEngine * const engine = platformTheme ?
platformTheme->createIconEngine(name)
: new
QIconLoaderEngine(name);
QIcon *cachedIcon = new QIcon(engine);
icon = *cachedIcon;
qtIconCache()->insert(name, cachedIcon);
}
// Note the qapp check is to allow lazy loading of static icons
// Supporting fallbacks will not work for this case.
if (qApp && icon.availableSizes().isEmpty())
return fallback;
return icon;
}
for the moment I don't understand why it doesn't work. Perhaps
CollectionUtils::displayIconName has a problem.
I will look at.
