Hm, for some reason, pushing the commit did not close the bug report. Here it is:


Note that this commit is currently only in the master branch (which is going to become KDE 4.12). Considering that the bug is not a big showstopper and that the fix required some non-trivial changes in important classes, I prefer not to commit it to the 4.11 branch right now. It would not get much testing before KDE 4.11.0, and I do not want to risk regressions.

Git commit 69c9100f91775560fe75f7910fd18a649fadaad1 by Frank Reininghaus.

Make sure that widgets are initialized when changing the view mode

The problem was that DolphinItemListView overrides the virtual function
onItemLayoutChanged() without calling the base class implementation.
Therefore, KStandardItemListView::updateLayoutOfVisibleItems(), which
calls initializeItemListWidget(), is never called.

This patch refactors the "change item layout"/"supports item expanding"
code a bit to make it more robust and fix the problem that the view
looks "messed up" when switching from Details View without expandable
folders to Icons View.

I'm only pushing this patch to master (going to be KDE 4.12).
The patch is a bit too intrusive for the KDE/4.11 branch for my taste
at this point of the release cycle, and the bug is not a real
showstopper. If it works well in master, one could consider backporting
it to a 4.11.x bug fix release.

Thanks to Emmanuel Pescosta for helping to analyze this issue.
