I'll look into this issue for KDE 4.8.2, unless someone else wants to give this a try :-)
Comment 2 Peter Penz 2012-03-06 07:46:21 UTC
Would be great of course, thanks :-) One note: Although it worked in 4.7 it still was not perfect there too. When the pasting resulted in several copy-operations (e.g. it took lets say 10 seconds), then only the first series of pasted items got selected.

Created attachment 69926 [details]

In Dolphin 1.x, selecting pasted or dropped items was done using DolphinView's m_newFileNames member. In the big "Dolphin 2.0" commit, this member was removed - it looks like the idea was to let m_selectedUrls handle that. However, this can only work if the path of the pasted or dropped URLs is modified, such that the URLs in m_selectedUrls are really URLs inside the folder shown in the view (i.e., m_selectedUrls must store the *destination* URLs, not the *source* URLs of the paste/drop operation).

The attached patch fixes it. Additionally, it clears the old selection in DolphinView::updateViewState() before the URLs in m_selectedUrls are selected. This is expected when URLs are pasted/dropped. I think that this does not have any unexpected side effects here.

The remaining things to be done are:

1. Port my old DolphinView unit test, which covers selecting pasted URLs, to Dolphin 2.0 (I really should have done this earlier)

2. Make sure that selecting pasted URLs works even if the copy operation is slow, such that the dir lister emits its completed() signal multiple times before the pasting is finished

These things take a bit more time to implement, which is why I'm posting the patch now. At least we can restore the Dolphin 1.x behaviour in time for KDE 4.8.2 then.

Thanks Frank for the patch - I think I'm to blame for removing the corresponding code :-(  Please feel free to commit the current version of the patch!
