Hello,
I've got a little problem with a few UDSEntry that represent virtual folders: in my code I place a size for each entry like the following but when I right click on the folder from konqueror and ask for the folder size it always displays zero bytes.

Code: Select all

UDSEntry entry;
...
entry.insert( KIO::UDSEntry::UDS_SIZE,  2000 );


I've checked that the value (2000) in this case is effectively placed into the UDSEntry. Am I misunderstanding the size attribute?

The size of a folder (as shown in the properties dialog) is the sum of the size of all the contents of the folder.

Not UDS_SIZE, which is the size of the item itself, which makes no sense for folders (e.g. on an ext3 filesystem, a folder entry takes 1K or 2K or 4K on disk, as shown by ls -l, but the user doesn't really care about that, so konqueror/dolphin doesn't display that).

You should check whether listDir is correctly implemented, and whether files themselves have a UDS_SIZE -- that's what kpropertiesdialog sums up.

If you only display folders, no files, then there's a problem indeed
Maybe KIO itself can be changed to take into account UDS_SIZE for folders, after double-checking that none of the existing kioslaves set that...
