Fix warning on launch "QPixmap::scaled: Pixmap is a null pixmap"
If Dolphin is launched with the information panel on and set to display
previews, PixmapViewer::paintEvent is called three times before any
pixmap is set. Each time the above warning message is output.
Fix regression concerning the "Places" selector in the location bar
This commit ensures that the selector is visible in all location bars
if and only if the Places Panel is hidden. It fixes a regression caused
by commit 6a98d83312ff2b14ab878e1427bbace3b683eacc.
Avoid opening unused tabs which are closed again after startup has finished (when directory/file urls are given)
Instead of always opening a new tab with the home url and closing it again when directory/file urls are passed on,
we now use the given directories/files directly to open new tabs on startup.
Makes the code easier and we can reuse openDirectories/openFiles in future (if needed).
Improve drawing selected items in Compact/Details View and Places Panel
This commit removes the icon tinting for the selected item in Compact
and Details View, and extends the selection rectangle such that it
includes the icon area as well. The icon tinting can be disturbing, and
having a selection rectangle that only includes the text can look a bit
strange, especially in the Places Panel.
Remove current item highlighting in the Places Panel
In the Places Panel, there is always exactly one selected item, which is
equal to the current item. Since the selected item is highlighted by
drawing its background in a different color, it is not really necessary
to highlight additionally that it is the current item.
This is achieved by removing the calls to
KItemListWidget::setCurrent(true) from KItemListView. The "current"
information in the widget is only used for deciding if the "current item
highlighting", like an underline in Oxygen, should be drawn.
The motivation for this change is that I have seem some complaints about
the "current item" highlighting, which can be even more distracting with
non-Oxygen styles.
Do not crash if QApplication::clipboard()->mimeData() is a null pointer
This removes the remaining unchecked accesses to the clipboard mime
data after commit 7828b057da0491f1b08bfaec681067e195d7b6ca. According
to a bug report, it can be a null pointer on Wayland.
Separate width and height info in the layouting code
By separating the width and height info, we can save some unnecessary
overhead in terms of memory and CPU cycles, and make the calculation of
the height of a row (or the width of a column in Compact View) a bit
simpler.
To achieve this, this patch extends the concept of "logical rows"
(which are actually columns in Compact View) to "logical width" and
"logical height" (which is the actual height and width, respectively, in
Compact View). The distinction between rows/columns and "logical"
rows/columns may be a bit confusing, but the confusion is already in the
current code, and I hope that it will be mitigated a bit by prefixing
the corresponding variables with "logical".
Fix possible crash if a kioslave adds multiple items with the same URL
When opening the URL "man:", there are multiple items with the same
name (for example, _exit is shown twice here). When opening a new tab,
the kioslave reports some items as deleted (I have not quite understood
why). The problem is that it reports some of the duplicate items twice
in the list of deleted items. This confused KFileItemModel and
corrupted the internal data structures, and finally, caused a crash.
The fix is to remove all duplicates from
KItemRangeList::fromSortedContainer(const Container& container).
Keep the "free space" information updated in all visible views
The old code would watch the free space on a mount point, i.e.,
determine the free space again, in 10-second intervals, only until the
view became invisible once (even if it was invisible only for a very
short moment, i.e., while splitting the view).
This commit ensures that the mount point is watched again as soon as
the corresponding view becomes visible again.
Moreover, the object that watches the free space for a mount point is
shared among all views that show URLs that belong to this mount point.
To achieve this, there is a central cache which can be used to obtain
an existing MountPointObserver for a certain path. If necessary, a new
MountPointObserver is created and added to the cache.
The MountPointObserver is removed from the cache and destroyed only if
no views use it any more, and no new users appear until the next update
(which happens every 10 seconds). This prevents that the free space is
measured repeatedly when changing the current directory on the same
mount point.
Many thanks to Emmanuel Pescosta for the initial ideas to factor out
the "free space" code and to establish a central storage for the
"observer" objects, and for providing many good suggestions how to
improve the code!
Do not lose translation of Places items if a Dolphin window is closed
If the "Places" are updated outside the current Dolphin process,
PlacesItemModel::updateBookmarks() is called, which invokes
PlacesItem::setBookmark(const KBookmark& bookmark) for each item. This
commit ensures that the correct translation is used for system
bookmarks like "Root", "Network", etc.
Without this patch, all Places entries in the remaining Dolphin windows
would switch to US English if one of multiple windows is closed.
See http://lists.kde.org/?t=139660468400004&r=1&w=2 for details.
Before this patch, KDirLister would continue listing any children of
collapsed folders, even though the children themselves were removed
from the model. This could lead to new items being inserted as
top-level items at some later point, because no parent could be found
for them. This inconsistent model state could lead to a crash later on.
Many thanks to Martin Koller for helping to debug this problem!
Ensure that all children of a collapsed folder are removed
Before this patch, any (direct or indirect) children that might have
been in m_pendingItemsToInsert, i.e., that were not inserted into the
model yet because KDirLister had not finished listing the directory
yet, would be added to the model later without a proper parent. This
could cause a crash later on.
Updating this action is only required if the clipboard contents change,
or if the "is writable" state of the current location changes. In all
other cases, an update of this action should be prevented because it
can be very expensive if many files are in the clipboard.
In particular, the update when the selection changes could make
changing the current item in the view very slow.
Change the icon text for Previous and Next toolbar buttons
In addition to the current long text for previous and next toolbar
buttons ("Activate Previous/Next Tab"), this commit adds shorter icon
texts for them to be used only on the toolbar ("Previous/Next Tab").
Instead of just emitting the slotItemMiddleClicked signal in
PlacesPanel::slotItemContextMenuRequested we now use triggerItem with
Qt::MiddleButton, which does set up the storage first and emit
the slotItemMiddleClicked signal afterwards.
Do not change the selection when re-sorting the view
If a range of items has been selected by Shift-clicking or by pressing
Shift+Arrow, then each of them is added individually to the selection
before the items are re-sorted.
Before this commit, the first and the last item in the range were
moved, and all items between them were selected, even though these were
not necessarily the items which had been selected before the
re-sorting.
Fix memory leak with Dropbox version control plugin.
In the current version we only call endRetrieval when
beginRetrieval was successfully in UpdateItemStatesThread::run().
This causes some problems with version control plugins (like Dropbox plugin),
which have to do cleanups in endRetrieval.
Now we always call endRetrieval after beginRetrieval when updating the version states.
Scroll to the right position when going back and show hidden files is enabled.
Instead of emitting the directoryLoadingCompleted signal (via slotCompleted) in
KFileItemModel::setShowHiddenFiles directly, we now call
dispatchPendingItemsToInsert instead.
The icons of items which are "cut" are shown faded in the view. The
"is cut" state of the widget representing an item is updated if the
clipboard contents change. Before this commit, if the sort order was
changed however, then each widget kept the "is cut" state of the item
which had been shown previously at its position.
The solution is to update the "is cut" state also if any of the
widget's data change.
KDirectoryContentsCounter: do not delete currently active worker objects
Before this patch, the destructor of KDirectoryContentsCounter might
delete the worker object, which lives in another thread, while one of
its methods was still being executed. This could cause a crash. Only if
the destroyed KDirectoryContentsCounter was the last one, the worker
thread was stopped, and the destructor waited until all workers are
done.
When you open a new tab while the search mode is enabled, the
newly opened tab also starts the same search (Because new tab is opened with
the current view url), but the search box is in read-only mode. So you cannot
close the search bar nor edit the search text.
This patch fixes this by parsing the search url. The value of the "search"
parameter is used as search text and the value of the "url" parameter is used
for the search path ("root" folder for the search when "Search from here" mode
is enabled).
In case of Baloo search urls, we use Baloo::Query::fromSearchUrl.
Removed everything related to read only mode in DolphinSearchBox, not needed
anymore.

Dolphin Facet Widget: Convert type selection into radio buttons
They were previously checkboxes. Most files cannot have more than 1 type
considering that the exposed types were "Document", "Image", "Video" and
"Audio".
Also, it is not very simple in baloo to search through ORs for types.
Not through the exposed API anyway.

Dolphin Facet Widgets: Implement date based filtering
This required changes in Baloo which require reindexing. Since the
storage location has changed for Beta 3 everyone should be re-indexing
everything, so it won't be a problem.
Use MIME type inheritance to find out if a file contains text
Before this commit, filenamesearch checked if a file's MIME type begins
with "text/" to determine if its content can be searched. This prevented
that text inside shell scripts is found.
Use QMutableHashIterator for deleting items from a QHash
KItemListViewAnimation::slotFinished() used a QHashIterator to iterate
over a QHash, and then removes an item from the hash using
QHash::remove() inside the loop.
This is quite unusual - the recommended way is to use a
QMutableHashIterator (or std-style iterators and then QHash::erase(it)).
This might be related to the cause of a crash in this function.
Always go back/forward in history when pressing the respective buttons
Before this patch, pressing one of these buttons while an item is
hovered selected this item. The motivation for this behavior was to
provide a fast way to select items. However, this was counter-intuitive
and confusing for many users.
Make the handling of the "maximum text lines" setting more robust
If the user sets a maximum number of text lines in the settings, this
number was translated into a maximum height in pixels using
QFontMetrics::lineSpacing() before this commit.
In KStandardItemListWidgetInformant::itemSizeHint(), this maximum height
limited the size that is reserved for the item.
However, in KStandardItemListWidget::updateIconsLayoutTextCache(), the
maximum height was translated back into a maximum number of lines,
which limits the number of lines that are created using the QTextLayout.
This approach could lead to problems if the real height of the layouted
text is 1 pixel more or less than QFontMetrics::lineSpacing() times
"number of lines".
Now we do not store a "maximum height" inside the "maximum size"
explicitly, but store a maximum number of lines and a maximum with (for
Compact View) separately, and then use the number of lines also to
calculate the required size in
KStandardItemListWidgetInformant::itemSizeHint(). This should make sure
that the correct height is reserved for each item.
Thanks to Christoph Feck and Emmanuel Pescosta for helping to debug this
problem and testing the patch.
Ensure that KItemListViewLayouter always has a size hint resolver
KItemListViewLayouter uses a KItemListSizeHintResolver to find out how
much space the items will need in the view.
Before this commit, the size hint resolver object could be changed at
runtime, and it could also be null. However, we never made use of these
possibilities, so all the code that checks if m_sizeHintResolver is
null is actually not needed at all.
Only initialize the hash m_items in KFileItemModel if it is needed
Moreover, clear the entire hash if items are added or removed.
This saves time and memory when loading a directory, and it fixes
problems that might occur if the model is in an inconsistent state, such
as crashes that can happen when we try to remove individual items from
m_items.
Restore the URLs of both views correctly when restoring a session
The problem was that we restored the URL of the right view while the
left one is still active. When we received the signal
urlChanged(KUrl& url) from the right URL navigator, we then set the URL
of the active (i.e., left) view to 'url', such that both views showed
the same URL.
Always enable the "Create New..." menu if the URL is writable
This commit works around the problem that KDirLister may not provide a
"rootItem" for some kioslaves by setting up a KFileItem with the view
URL and using this to find out if the URL is writable.
Use only one "directory contents counting" thread per process
The pointer to QThread object is stored in a global variable, and each
view increments/decrements a reference count when it starts/stops using
the thread. If this thread reaches zero, the thread is stopped.
Note that we cannot just use a smart pointer, like QSharedPointer, to
manage the thread, because we must make sure that the thread is not
running any more before the QThread is deleted.
