Marcel, thanks a lot for the detailed explanation!
So from my point of view, there are two things
a) automatically pre-generate the thumbnails on disk for all images
in the current album.
This process should stop, when changing to a different view.
b) maybe pre-load the next line (or next two lines) into the pixmap cache.
Here b) should only give a slight improvement, as a) is the crucial point.
So my question is:
What kind of infrastructure could be used to achieve a)?
If nothing is there for this, maybe it is better to deal with
this issue in the KDE4 branch?
For b) I thought that the above mentioned:
IconItem *fItem = firstItem();
IconItem *lItem = lastItem();
should technically work in AlbumIconView::nextItemToThumbnail(),
but this doesn't. Maybe this should be replaced by
IconItem *fItem = findFirstVisibleItem(r);
IconItem *lItem = findLastVisibleItem(r) + 10;
// metacode, but you get the idea
(Maybe you addressed already in your reply, why this can't work ...)
Best, Arnd
