When groups are enabled in Dolphin the key-up and key-down keys did not behave
consistent in comparison to traditional views or like done in editors.

When having a row with different item-heights, the calculation of the
first visible index might have been wrong.
|
|
- Disable performance debugging output
- Force a synchronous layout during scrolling. This prevents having a jerky
scroll-animation if there are pending operations ongoing in parallel.
- Minor coding style cleanups
|
|
The maximum scroll offset must be the maximum y-range of the last
row, not only the maximum of the last item.
Thanks to Frank Reininghaus for analysing the root-cause and
for providing the initial patch!

When expanding/collapsing folders in the tree-view the visibility
of group-headers got unpredictable.

- Apply a dynamic width
- Use a height that depends on the style
- Cleanup some interfaces and replace xxxBoundingRect() by
xxxRect()

The most tricky part for groups - the layouting - basically works
now for all views (grouping was available only in the icons views
for Dolphin 1.x) and is nearly equally fast as without groups.
Still open:
- Group headers are ugly screen rectangles
- Return valid groups in KFileItemModel instead of the currently
hardcoded testing values
- Dynamically turning on/off groups does not work currently, the
directory must be reentered
|
|
- Rename setCategorizedSorting() to setGroupedSorting()
- Change the model interface to allow enabling/disabling grouping
without the need to declare a role (the sort role will be taken).
- Add dummy group role implementation in KFileItemModel
The grouping code itself requires some cleanups and might crash
at the moment or lead to weird layouts.

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.

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.
