2008-06-01Improve the performance when creating previews for thousands of items by the ↵Peter Penz
following strategy: - The previews for currently visible items are created before the previews for invisible items. - If the user changes the visible area by using the scrollbars, all pending previews get paused. As soon as the user stays on the same position for a short delay, the previews are resumed. Also in this case the previews for the visible items are generated first. svn path=/trunk/KDE/kdebase/apps/; revision=815480

2008-05-29Before applying the cut item effect to a preview, assure that the cut items ↵Peter Penz
cache gets an update of the preview without effect. This assures that when cutting other items that the state of the previously cut items can be restored in any case. svn path=/trunk/KDE/kdebase/apps/; revision=814273
2008-05-07SVN_SILENT: minor coding style fixesPeter Penz

2008-05-06* prevent that cut icons are shift left in the icons view by using the ↵Peter Penz
correct size * apply cut item effect before generating previews BUG: 161707 svn path=/trunk/KDE/kdebase/apps/; revision=804768

svn path=/trunk/KDE/kdebase/apps/; revision=800783
2008-04-08don't apply a frame to image previews, if the preview is a very small image ↵Peter Penz
(e. g. an icon) CCMAIL: [email protected] svn path=/trunk/KDE/kdebase/apps/; revision=794783
2008-03-23The background for the image previews is already filled, so there is no need ↵Peter Penz
adding a border with the background color again (this also fixes a one-pixel-issue that shaded the right/bottom border in a wrong way). svn path=/trunk/KDE/kdebase/apps/; revision=789234
2008-03-23minor code simplificationPeter Penz
svn path=/trunk/KDE/kdebase/apps/; revision=789193
2008-03-23take care to restart the timer even when no previews are in the queue: as ↵Peter Penz
long as preview jobs are working, new previews will arrive svn path=/trunk/KDE/kdebase/apps/; revision=789066
2008-03-23Performance boost for previews that are already available in the cache: ↵Peter Penz
apply the previews in larger blocks instead of applying them immediately after getting the signal 'gotPreview' from the PreviewJob. Now the previews in Konqueror and Dolphin are as fast as in the good old KDE 3 days :-) svn path=/trunk/KDE/kdebase/apps/; revision=789009
2008-03-15dim image frame only by 12.5 % instead of 25 %Peter Penz
svn path=/trunk/KDE/kdebase/apps/; revision=785957
2008-03-13Remove the semitransparent effect for hidden items in the IconManager, it ↵Peter Penz
just takes too much time at this part of the code. David Faure suggested some alternative ideas, I hope I can try them before KDE 4.1. Currently it is more important to keep the performance high. BUG: 158807 svn path=/trunk/KDE/kdebase/apps/; revision=785369
2008-03-10update the previews without relying on that KDirLister gets reloadedPeter Penz

svn path=/trunk/KDE/kdebase/apps/; revision=782795
2008-03-06ignore the width when getting an icon for applying the "hidden files" ↵Peter Penz
effect, otherwise a wrong horizontal alignment is done svn path=/trunk/KDE/kdebase/apps/; revision=782786
2008-03-05provide an unintrusive frame for previews of imagesPeter Penz
svn path=/trunk/KDE/kdebase/apps/; revision=782785
2008-02-16Provide an option for the details view to expand folders (= tree view), as ↵Peter Penz
this is required for Konqueror to get back this functionality from KDE 3. It is possible in Dolphin to enable this option too, but it is set to false per default. BUG: 155571 svn path=/trunk/KDE/kdebase/apps/; revision=775621
2008-01-28fixed issue that previews of hidden files had no semitransparent effect (the ↵Peter Penz
semi-transparent effect requires having an alpha mask) svn path=/trunk/KDE/kdebase/apps/; revision=767742
2008-01-28* replace item.name().startsWith('.') by item.isHidden()Peter Penz
* removed redundant applying of a hidden item effect before starting the preview svn path=/trunk/KDE/kdebase/apps/; revision=767730
2008-01-26* increase the performance of item previews: each item view provides an icon ↵Peter Penz
size hint -> the preview and item effects are only applied to the current size, not to the maximum of 128 x 128 pixels * make the icons of hidden files semitransparent like in KDE3 svn path=/trunk/KDE/kdebase/apps/; revision=766659
2008-01-13Improve the feeled preview performance by assuring that the preview is ↵Peter Penz
generated first for the visible items. svn path=/trunk/KDE/kdebase/apps/; revision=760897
2008-01-11Up to now DolphinView and ColumnWidget contained a lot of code duplication ↵Peter Penz
regarding generating previews and the dimming of cut items. This has been refactored by introducing an IconManager which takes care itself about generating a preview and dimming cut items. This also allows improving the speed of previews in (near) future (at the moment showing previews from the cache is a lot slower than in KDE 3...). svn path=/trunk/KDE/kdebase/apps/; revision=759864
