Description Mikolaj Machowski 2007-11-20 23:06:37 UTC 
Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc4.3 
OS:                Linux

When opening panels viewport of Album is changed - it moves upward.

The main consequence is vanishing of selected image from view. For best reproduction select album with many pictures (requiring several PagesDown to go to the bottom) and select last  image. Then open and close several times eg. Properties panel. In many situations picture vanishes after just one round. After many rounds you can go to the top of album.

Selected album should stay visible.
Comment 1 Paweł Marciniak 2007-11-21 01:21:35 UTC 
The problem is caused by the fact that in IconView::slotRearrange(), IconView::ensureItemVisible() is called with d->storedVisibleItem as a parameter. That variable is previously set to findFirstVisibleItem() in IconView::triggerRearrangement();

As a result, when changing the IconView size from A to B, visibility in B is set to the first item that was visible in A size, instead of the current item.

Comment 3 Mikolaj Machowski 2007-11-21 19:38:35 UTC 
There is very similar bug with text filtering. After clearing of field
viewport jumps up. This is not the case with filetype and rating
filtering - selected item stays visible.
Comment 4 Andi Clemens 2009-10-20 17:48:44 UTC 
Is this bug valid? In dolphin for example a selected item is not staying in the exact position either, when opening panels (for example F11: Information).

Can you reproduce the problem with this release ?

With digiKam 5.0.0  this problem is not reproducible.
I close this file now. Don't hesitate to re-open if necessary.
