2012-04-11KItemViews: Internal directory restructurationPeter Penz
- Move all private headers from the kitemviews-directory into the 'private' subdirectory. - Get rid of DolphinDirLister and just use a directory-lister internally in KFileItemModel. - Minor interface-cleanups for signals
2012-04-10Improvements for slow sorting rolesPeter Penz
If the sorting is done for data which is resolved asynchronously (e.g. rating), it is important to give a visual feedback about the state of the sorting. This is done now by a progress indication in the statusbar. Also optimizations for "Sort by type" have been done: Although resolving a type can be expensive in the most often case it is a very cheap operation. So it the sorting is done by type, try to resolve the type synchronously for at least 200 ms to prevent a asynchronous resorting. This is usually sufficient to have resolved types even for directories with several thousands of items. BUG: 292733 FIXED-IN: 4.9.0
2012-04-08Ignore maximum size for local files when creating previewsPeter Penz
It is up to the plugins to decide what sensible size is required for creating a preview, this cannot be decided by the user for all plugins. A maximum size only makes sense for remote files, where the user implicitely decides how much of the bandwith may be used for having previews. BUG: 273226 FIXED-IN: 4.9.0
2012-04-08Remove unneeded/wrong signal-slot-connectionPeter Penz
2012-04-06Allow to specify whether an upscaling of images should be donePeter Penz
The option is currently hidden as up to now only Nuno requested it, but it seems to be urgent: "my icon making productivity has drop subtantialy" ((c) 2012 Nuno) As I don't want to get blamed for an outdated Oxygen-icon-set I have no other choice ;-) CCMAIL: [email protected]
2012-04-06Update items if a Nepomuk property has been changedPeter Penz
If a Nepomuk property has been changed (e.g. by changing the rating in the Information Panel) the corresponding item in the view must be updated.
2012-04-01Allow showing Nepomuk metadata inside viewsPeter Penz
Metadata like image-size, rating, comments, tags, ... can be shown now in the view (e.g. as column in the Details mode). Still open: The rating-information needs to be shown as stars. In the context of this feature also the following bugs have been fixed: - Fix visual glitches in the header of the Details mode - Improve the minimum column width calculation to respect also the headling and not only the content BUG: 296782 FIXED-IN: 4.9.0
2012-03-21Prevent flickering when updating itemsPeter Penz
When downloading images from e.g. the camera-IO-slave the files will be downloaded as *.part files and renamed afterwards. The renaming results in an undetermined mimetype and hence the probably already available preview or icon gets replaced by a dummy icon. The patch fixes this by keeping the old values as long until they have been resolved by KFileItemModelRolesUpdater.
2012-02-23Whitespace cleanups and documentation fixesPeter Penz
2012-02-21Don't trigger assert when switching to details-viewPeter Penz
If the visible roles of the details-view are equal to the visible roles of other views, then switching to the details-view will trigger an assert because the invisible roles don't get updated. Thanks to Frank Reininghaus for the detailed analyses! In the context of this fix optimizations have been done when switching view-modes: The "don't-animate-workaround" could be removed. BUG: 294531 FIXED-IN: 4.8.1
2012-02-03Show the value "Unknown" for the item-count only after it has been verifiedPeter Penz
During determining the item-count for directories just show an empty string until either the item-count has been calculated or if the item-count is unknown. Thanks to Nikita Skovoroda for the initial proof-of-concept patch. BUG: 291823 FIXED-IN: 4.8.1
2012-02-03Folders Panel: Show expansion toggles for directories on ISO-imagesPeter Penz
When counting the number of sub-directories consider unknown file types as potential directories. In the "worst case" an expansion toggle will be shown although the directory contains only files, however from a performance point of view this seems to be an acceptable compromise. BUG: 292642 FIXED-IN: 4.8.1
2012-02-01KFileItemModelRolesUpdater: Optimize updatesPeter Penz
The asynchronous resolving to bypass performance bottlenecks is not necessary anymore as multiple ranges can be inserted in one step now. This solves the issue that e.g. opening a tree resulted in temporary unknown icons for a short period of time.
2012-01-15Don't show a expanding-toggle in the Folders Panel if there are no ↵Peter Penz
subdirectories BUG: 290745 FIXED-IN: 4.8.0
2012-01-11Prevent accessing an item with an invalid indexPeter Penz
2012-01-09Prevent generating previews all the time during downloading a large filePeter Penz
When downloading a large file the preview should not be recreated each time a change-notification has been received. Create the preview after getting the first file change, but postpone creating the next previews until no change has been done during a longer period of time. BUG: 290698 FIXED-IN: 4.8.0
2011-12-23Introduce "isExpandable" rolePeter Penz
The role is used to determine whether a directory can be expanded at all. This is e.g. not the case if a directory has 0 items or the target-URL is different from the item-URL. The expansion toggle will get hidden if a directory is not expandable. CCBUG: 288521
2011-12-21Update previews when the preview-plugin settings have changedPeter Penz
Thanks to Janardhan Reddy for the initial patch. BUG: 288726 FIXED-IN: 4.8.0
2011-12-16Minor layout and coding style cleanupsPeter Penz
- 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
2011-12-16Update the roles if items have been changedPeter Penz
The code "// TODO..." in slotItemsChanged() obviously was not sufficient ;-) BUG: 288691 BUG: 288824 BUG: 288921 FIXED-IN: 4.8.0
2011-12-10Fix issue that icon overlay is missing for linksPeter Penz
BUG: 288609 FIXED-IN: 4.8.0
2011-12-07Fix issue of unknown icon-typesPeter Penz
If the split-view is used and/or the Folders Panel is activated it might happen that the "unknown"-icon of an item is shown instead of the correct icon. The root-cause is that one model might already have been resolved the MIME-type of a KFileItem while the other model has not updated the icon yet. As KFileItems are shared the check whether the MIME-type has been resolved is wrong. As at that stage it is assured anyhow that the MIME-type is known just applying the icon-name in any case won't slow down the performance.
2011-12-04Fix crash #2 when filtering itemsPeter Penz
When KFileItems get removed from the model it is temporary possible that the pending items are still part of the KFileItemModelRolesUpdater while they have already been removed from the model (this happens in the context during the signal itemsRemoved() gets emitted). BUG: 287642
2011-12-04Make sure that enabling previews triggers the generation of previewsFrank Reininghaus
Before this commit, no previews were generated if the icon size was the same with and without previews.
2011-09-16Fix crash when expanding/closing a sub-treePeter Penz
m_pendingItems and m_pendingInvisibleItems might contain already removed items. Take care to delete them before starting to resolve the roles. Thanks to Frank Reininghaus for finding out the root-cause.
2011-08-13Fixes for "krazy"Peter Penz
2011-08-02Improve performance for creating previewsPeter Penz
The overall time for creating previews is faster the more items are passed to KIO::previewJob() in parallel instead of passing e.g. only 100 items once and start several KIO::previewJobs sequentially. However in the worst case KIO::previewJob() might block the application for several seconds if the MIME-type of the passed KFileItems are unknown and e.g. 10000 items are forwarded. So KFileItemModelRolesUpdater will now take care to resolve as many MIME-types as possible until a timeout is reached and will only pass those items to KIO::previewJob(). For huge image folders, where the MIME-type can be determined very fast, this means that the overall time for creating previews will decrease without blocking the application. For "worst case" directories where resolving the MIME-type can get very expensive this approach assures no blocking of the user-interface although the overall time until all previews are generated might slightly increase.

2011-07-30Merged very early alpha-version of Dolphin 2.0Peter Penz
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.
