The fix for bug 161385 (which was about Dolphin still showing an empty
view if a device that had been unmounted earlier was clicked in the
Places Panel) caused a regression: the view state (current item, scroll
position, Details View expansion state) was not restored any more when
going "Back".
The reason is that "m_view->reload()" in
DolphinViewContainer::setUrl(const KUrl& newUrl) was always executed
just after entering a directory, and that command overwrites this
information.
Distinguishing between "change URL" and "reload the view" works better
if it's done in DolphinMainWindow instead of DolphinViewContainer.

1. Remove the unneeded variable rowCount.
2. Simplify the calculation of the member m_maximumScrollOffset. We can
just use the current value of "y" because this is the offset that
the next row would have.

If the number of selected items is not two, Dolphin disables this
action. However, it is still possible to trigger it via D-Bus, and this
could cause a crash in DolphinMainWindow::compareFiles() because this
function did not test at all if there are really two items selected.
This patch adds such a check and simplifies the code in that function.

With this patch, Dolphin ignores all files passed to it that it can't
Also, archives are now opened inside Dolphin so it can be used as an
archive manager at least for local files. If the user tries to open a
remote archive Dolphin still opens it externally; I have observed that
if it receives one as an argument, it will display a pseudo-folder that
contains only said archive. So having it set as the archive handler is
still broken, but in a less annoying way.

When we remove items from the model, we called the function
KFileItemModel::removeItems(const KFileItemList&, RemoveItemsBehavior).
This function then looked up the indexes of the items using the hash
m_items. This is wasteful in the situations when the indexes of the
removed items are known in advance (like when an expanded folder is
collapsed in Details View), and it can cause trouble if one item is
contained in the model multiple times (can happen when searching, and a
file both matches the search and is a child of a folder that matches
the search). Even if expanding folders in the search results list might
not be particularly useful most of the time, it makes sense to make the
model more robust to prevent crashes and other unexpected behavior in
such situations.
This patch makes the following changes to achieve that goal:
* Change the argument of removeItems() from KFileItemList to
KItemRangeList. To make this work, the "look the indexes up in
m_items" code is moved from that function to slotItemsDeleted(). In
the other places where removeItems() is called, the indexes are
calculated directly (which is not more difficult than determining the
removed items as a KFileItemList, if one considers that we needed the
function childItems(KFileItem) for that, which is not needed any more
with this patch).
* Also removeFilteredChildren() takes a KItemRangeList now. Rather than
putting the parent KFileItems into a QSet for O(1) lookup (which
prevents O(N^2) worst case behavior for the entire function), it uses
a QSet<ItemData*> now, which should even be more efficient (hashing a
pointer is cheaper than hashing a KFileItem/KUrl).

The problem was that DolphinViewContainer::setUrl(newUrl) was ignored
if newUrl is equal to the URL which is shown in the view already.
The new approach is to reload the view in that method if it is empty, to
make sure that we do not miss that a previously unmounted device has
been re-mounted.
Thanks to Grigoriadis Grigoris for analyzing the root cause of this
issue!

Before this commit, we only added pressed keys to the search string if
they have no other meaning. This means that files containing a Space in
their name could not be searched because Ctrl+Space toggles the
selection state of the current item, and Space alone selects the
current item.
After this commit, Space is added to the search string if
(a) the key press did not have any other effect, i.e., if Ctrl was not
pressed, and the current item is selected already, and
(b) a keyboard search has been started already (to prevent unexpected
effects when pressing Space accidentally - I think that it's rather
uncommon to have files whose names start with a Space - and to make
the unit test simpler).
I modified the unit test of KItemListController, which did not test
keyboard search yet. This uncovered a small problem in
KItemListController::slotChangeCurrentItem() when NoSelection mode is
used. It's not really relevant for anything that is executed inside
Dolphin, but I still fixed it to make the unit test happy.

To reduce unnecessary memory comsumption and CPU usage, we only fill the
QHash<QByteArray, QVariant> if the methods data(int) or setData(int) are
called for the corresponding index, or the data is necessary for sorting
the model.
According to my tests, this patch reduces the memory usage when loading
a folder with 100,000 items by 17% in Icons View, and by 26% in Details
View.

This prevents a possible regression that would have happened with the
first version of https://git.reviewboard.kde.org/r/112725/
The problem was that isChildItem(int index) would return "false"
incorrectly when the QHash for that item was not initialized yet. The
grouping code would then try to read the "text" from the empty QHash,
which yielded an empty QString, and then accessing the first character
of that string caused a crash.

Also factor out the code that transforms a sorted list of ints to a
KItemRangeList. This removes some duplicated code from KFileItemModel.
Note that overriding operator<<() in KItemRangeList was necessary
because it's not a typedef for QList<KItemRange>, but a class derived
from that now, and some code fails to compile if the return type of
that function is QList<KItemRange> and not KItemRangeList.

KFileItemListView notifies KFileItemModelRolesUpdater of changes of the
visible index range and the icon size with a delay, to prevent that
expensive operations are triggered repeatedly, and that scrolling feels
sluggish because the GUI thread is blocked by icon loading.
This patch ensures that the "long" delay of 300 ms is only used when
the zoom level is changed, and the "short" delay if only the visible
index range has changed.
Thanks to Christoph Feck for helping to analyze this problem!

When sorting by, e.g., "Size", and the name is used as a fallback
because there are multiple files with the same size, the refreshItems
signal that is received when a file's name is changed either with the
dialog or outside the current view did not cause the view to be resorted
after commit d70a4811807776966c3241a72121242f4d1eaee8. This patch fixes
it.

The most recent commit from the KDE/4.11 branch (new unit test) had to
be modified slightly due to the changed signal emission when resorting
the model changes only the groups, and not the order of the items
(groupsChaged instead of itemsMoved).

This unit test will hopefully prevent regressions in the future. It is
the first part of https://git.reviewboard.kde.org/r/112561/.

The idea is that we no longer assume that the "expandedParentsCount"
for each item will be stored in the QHash. It is only accessed for
items which are expanded, and which are not top-level items (i.e.,
which have an expandedParentsCount > 1).
Some unit tests are added to improve the coverage of the affected code.

Currently, KStandardItemListWidgetInformant::itemSizeHint() calls the
model's data(int) method for every single item, but the full data is
actually only needed for the size calculation in Compact View. In
Details View, no data is needed at all to determine the size required
for the item, and in Icons View, only the name is needed.
This patch makes it possible for subclasses of
KStandardItemListWidgetInformant to provide an alternative way to
obtain the "text", and implements this in the subclass
KFileItemListWidgetInformant.
The final goal is to achieve that the QHash which contains all data
for a file item is only created if it is really needed, e.g., because
the view needs access to the data for displaying the item on the
screen.

Removed all signal-slot-connections related to DolphinNewFileMenu->errorMessage(QString)
in DolphinMainWindow and DolphinContextMenu and replaced it by a better solution.
Now we make use of the already existing DolphinNewFileMenuObserver singleton class to achieve a better
error handling, because every newly created DolphinContextMenu instance registers himself by DolphinNewFileMenuObserver
and we use this to connect the errorMessage(QString) signal of every DolphinContextMenu instance to the errorMessage(QString)
signal of the DolphinNewFileMenuObserver singleton class.
So we need only one connection from DolphinNewFileMenuObserver to DolphinMainWindow (or to DolphinPart) to
collect all error messages thrown by every DolphinNewFileMenu instance.

When the name of a file is too long to be shown inside the maximum
number of lines, the last line is elided. However, there were several
problems before this commit:
(a) "lastTextLine", which contains the text to be elided, was not
assigned the complete remaining text, but only the part that would
be put into the last line if there were more lines following. This
may be less than what would fit into the line because we try to not
break the text at random points.
(b) QFontMetrics::elidedText() was not given the width that is available
for the last line (that would be maxWidth), but only the width that
would be occupied by the text if there were more lines following
(line.naturalTextWidth()).
(c) The variable "nameWidth", which is required to calculate the QRectF
that is reserved for the name, was not updated correctly.
The result is that the text was sometimes trucated too early (especially
if there would be a line break early in the text if we had more lines
available), that there may be insufficient space to show the "...", and
that the hover/selection rectangle might be too narrow.

KFileItem::determineMimeType() not only determines the mime type, but
also the icon. For folders, it looks for a .directory file inside the
folder, where a custom icon might be stored. This can take quite a bit
of time and cause the problem that some folder's type still appears to
be "unknown" when the view is shown.
We can work around this problem by caching the folder mime type in a
static QString and applying to to all folders, which can be identified
easily with KFileItem::isDir(),

This patch changes the status bar text dolphin shows when a folder is
hovered. It now shows full folder info, eg:
"mydir (folder, symlink to /opt/mydir")
instead of:
"mydir"
This is consistent with dolphin's behavior on regular files, and
DolphinPart already does that (DolphinPart::slotRequestItemInfo has no
special cases for folders).
