Up to now the view-engine only provided a model-implementation that
supports file-items. The view-engine always had been designed to be able
to work with any kind of model, so now a KStandardItemModel is available.
The plan is to convert the places panel to the new view-engine. It should
be no problem to fix this until the feature freeze - in the worst case
the places-panel code could be reverted while still keeping the
KStandardItemModel changes.

Usecase:
- No scrollbar is shown
- Window size will be decreased so that a scrollbar gets necessary
The decreased window size minus the space required for the scrollbar
results in a relayout of the items. In 99 % of all
cases a decreased window size won't result in showing more items in parallel in
comparison to a larger window size. However in the remaining 1 % this can
happen (e.g. see bug 293318 for a sample). This results in an endless loop as
now no scrollbar is required anymore, the layout changes again, the scrollbar
is required again, ...
BUG: 293318
FIXED-IN: 4.8.1

Currently only a smoothscrolling was provided into the
scroll-direction, but not in case of the details-view where a
horizontal scrollbar might be shown too.
Some minor adjustments of the private KItemListSmoothScroller interface
will be done later...
|
|
If an item does not fit into the available width/height a scrollbar
should be provided (e.g. typically this represents the horizontal
scrollbar in the details-view where the width can be larger than
the than the visible width).
Currently the interaction with the scrollbar is not implemented but
this will be a quite minor task in comparison to this patch.
|
|
The smooth-scrolling may only get turned off after finishing the
animation, if the scrollbar is not currently modified by the user.

If the autoscrolling has been activated when using the rubberband,
it was possible that an endless recursion occured as the
autoscrolling triggered a change of the rubberband which triggered
a change of the autoscrolling etc.
|
|
This is just a rough draft: The rubberband gets visible and an
automatic scrolling is done if the autoscroll-margins have been
reached. However currently no items get selected yet. Currently
the autoscrolling has a severe bug if the scrollbars are manually
changed before or after a rubberband selection.

Key press events are forwarded from KItemListContainer to
KItemListController. Right now, only the 'Home' and 'End' keys
are handled (arrow keys require some more work because their action
depends on the view mode).
Note:
1. Before key presses are handled, the view has to be clicked with
the mouse. It seems that the view does not have the keyboard
focus initially.
2. The view does not scroll to the new current item yet.

Dolphin 2.0 will get a new view-engine with the
following improvements:
- Better performance
- Animated transitions
- No clipped filenames due to dynamic item-sizes
- Grouping support for all view-modes
- Non-rectangular selection areas
- Simplified code for better maintenance
More details will be provided in a blog-entry during
the next days.
Please note that the code is in a very
early alpha-stage and although the most tricky parts
have been implemented already very basic things like
drag and drop or selections have not been pushed yet.
Those things are rather trivial to implement but this
still will take some time.
