Various work across Plasma, including improved applet handles with monochrome icons, work on the Weather Plasmoid and the start of an extender-based notification applet. Continued development in PowerDevil, including support for suspend. Long-standing "slow deletion of many files" bug is finally fixed. A System Settings module for choosing the default file manager. Basic implementation of red eye reduction in Gwenview. A generator for G3/G4 fax documents in Okular. Support for filter plugins in Kst. More work on code completion in KDevelop 4. Start of a D-Bus interface in Lokalize. First working implementation of KMenuEdit global shortcuts. Work on supporting different resources in the Akonadi OpenSync plugin. The return of Ark context-menu actions. Liechtenstein, Oman, and San-Marino maps in KGeography. Previews of slide transition effects in KPresenter now happen directly on the affected slide. A KFormula widget is extracted from KOffice and moved into kdelibs for use in other KDE applications. Work on porting Keep, a backup utility, to KDE 4. NEPOMUK query libraries move from kdereview to kdebase/workspace, with the search KIO slave moving into kdereview. A KDE 4 port of KnowIt, a note taking application, is imported into KDE SVN. Eigen 2.0 Beta 1 is tagged for release.

Ryan P. Bitanga introduces QuickSand, an alternative KRunner interface:
|
QuickSand is an alternative interface heavily inspired by the "Primer" interface of Quicksilver in Mac OS X.
QuickSand differs from the current KRunner interface in several ways. QuickSand has 3 different display modes: "Icon Parade", "Selected Item", and "Text" mode. The default display mode is "Icon Parade". Instead of displaying a line-edit, QuickSand presents the user with a matches pane asking the user to type something to be searched. Upon typing, the search string is displayed on the upper left corner of the matches pane. If matches are found, the number of matches is displayed on the upper right corner of the match pane. The icons are of the matches are lined up horizontally in the match pane and a pop-up completion box is shown to guide the user in selecting the appropriate match. The user can scroll through the available matches by pressing the up and down keys (when the pop-up box is shown) or the left and right keys.
Hitting <enter> will select the match and display only the selected item. Clicking on the arrow on the upper right corner of the match pane will toggle between "Icon Parade" and "Selected Item" modes.
If the user would rather see a line edit, pressing the <.> (dot) key will change the display to "Text" mode. A line edit will replace the scrolling icons in the match pane.
One of the primary reasons for writing QuickSand was to provide support for multiple actions. For example a match for an open application window can have several actions associated with it. The window can be minimized, set on all desktops, etc. QuickSand supports multiple actions in the same manner as matches for a search. If a particular match has several actions associated with it, an action pane appears below the match pane with the first action selected. Pressing <tab> will switch to the action pane and the user can select from the various available actions in the same manner as matches.
Hopefully, QuickSand will be provided as an option in KRunner allowing users to select between the default interface and QuickSand.
Another future development would be support for actions that require objects/targets. For example given a match for a file "screenshot.jpg" and an action of "e-mail to...", a possible object would be "danny@commit-digest.org". Support for objects would be as simple as placing an object pane below the action pane and displaying it whenever the currently selected action requires an object.

Gopala Krishna evaluates the progress made in the Summer of Code project for Umbrello:
|
Hi, my name is Gopala Krishna and I am currently pursuing Engineering in Information Science at Bangalore, India.
Umbrello is a KDE tool for UML drawing and it comes with the kdesdk module. Umbrello has been ported to KDE4 but still there are some rough edges here and there.
Google Summer of Code 2008 gave me an opportunity to contribute to KDE and I worked on the GraphicsView port of Umbrello and brought graphics bling into it. My mentor was the awesome Kubuntero, Jonathan Riddell.
I started with the literal Q3Canvas to GraphicsView transformation and intially succeeded removing the Q3Canvas dependency entirely. Of course, this broke almost all the drawing. Doing lots of string changes with the help of emacs, I could get the drawing back.
To continue, I had two choices for UML diagram widgets:
- Tweak the sources to restore all the broken stuff (mouse handling and others)
- Redesign them utilizing all the goodies provided by GrapicsView. (obviously more work but more futuristic)
I chose the second option as I love challenges! The first step was to redesign the base classes separately in a new namespace so that I could port the UML widgets incrementally. This base classes supported additional functionality like minimum/maximum size support, gradient fills, and so on.
Next came widget resizing mechanism. The previous version allowed resizing only from the bottom-right corner. I wrote a new class called WidgetHandle - a QGraphicsItem which handles all the resizing (all 8 locations) for a UML widget and also changes mouse cursor appropriately on hovering along any of the 8 locations. Here is file snapshot ;)
While trying to port UML widgets, I observed that a lot of widgets needed to display text and hence every class had to do lots of font calculation for handling drawing and geometry.
I came up with an idea to isolate all text handling stuff and I encapsulated them into TextItem and TextItemGroup classes. I evaluated the performance before this step, and you can find the results of evaluation here.
TextItems is one of the coolest parts of the project according to me, as this step led to the addition of support for rich text handling, hovering effects and tooltips, alignment, and also in-place editing of Widget's text quite easily. Isn't that cool?
Now almost all the UML widgets use TextItemGroups and TextItems to display their text which has freed them from the individual versions of font calculation code.
Here are screenshots of Umbrello showing some bling!
I am currently working on a new implementation of LinePath used to draw AssociationWidget lines. It sports new features, like highlighting the segment or point on the LinePath when the mouse hovers over it (for improved usability!):
My future plans involve integrating my work into trunk/ as soon as possible so that KDE 4.2 includes my work. I have plans to make the undo/redo handling more robust and implement cut/copy/paste based on XMI. And with the Umbrello community support, I think this is achievable :-)
The code is available at http://websvn.kde.org/branches/work/soc-umbrello/.

Germain Garand committed changes in /trunk/KDE/kdelibs/khtml:
|
* avoid NVidia+Qt4 buffer clearing problems, by making our widgets have a private buffer.
* for the same reason, always fully clear our shared opacity buffers - or we might get artifacts on NVidia cards such as on www.codetch.com/screenshots/ |

Finally fixing bug 43356: "deleting files in directories with more than 3000 files gets painfully slow" (from 2002, with 260 votes)
With model/view we can finally update the view in a better way: by chunks instead of item-after-item. This required adding a itemsDeleted signal to KDirLister, and some figure-out-consecutive-removals logic in KDirModel using QBitArray (for beginInsertRows).
Results:
Deleting 5000 files with konqueror-4.1: 8 minutes (30 seconds stat'ing, 5 seconds deleting, and then 7'25" until the view refreshes).
Deleting 5000 files with konqueror-trunk: 15 seconds (2 seconds stat+deleting, 13 seconds until the view refreshes). |

David Faure committed a change to /trunk/KDE/kdelibs/kio/kio/slave.cpp:

Nasty bug, this one, took a long time to debug.
Fix warning from scheduler saying "KIO::SchedulerPrivate::slotSlaveDied: Scheduler: BUG!! Slave KIO::Slave(0x6ee820) / 3788 died, but is NOT in slaveList!!!" simply because deref() used to delete the slave immediately in kde3, and delayed in kde4, so it would keep processing the replies sent by the slave. |

New special Code-completion within instantiated template classes.
This means you can jump into a template-class, see the actual types/values of all template-dependent types, and get code-completion on them.
To activate this, you current have to jump to the specialized declaration using the quickopen shortcut "CTRL+.".
Soon also to work with use-building and the context-browser, also this will get a little UI to change the template parameters while you're in a template. |

Rob Scheepmaker committed changes in /trunk/playground/base/plasma/applets/extendified_notify:
|
Start of an extendified notification applet.
Not only does this version use extenders for displaying notifications, it's also based on PopupApplet which means removal of a lot of duplicate code.
Code can maybe be cleaned up a bit more, but it basically works.
Only major regression: it no longer groups notifications of the same app.
To do this neatly, it would require grouping support in extenders and that's more something for 4.3 I think. |

Sebastian Kügler committed changes in /trunk/playground/base/plasma/runners/katesessions:
|
This Runner now loads a list of Kate's sessions and matches KRunner's queries against it.
It's pretty much ready to move into kate.
The matching goes as follows:
* You type "kate" into the krunner interface, this Kate Session Runner adds all kate sessions, with a low priority (0.5)
* You type "kate gnirrep" and the runner will find a session called "gnirrep", priority 1.0
* Typing just a part, such as "kate gnirr" also results in a match, but lower priority (0.8)
* Typing just the (parts of) the name of the session will also match (the "kate" in the query is optional).
All matching is case-insensitive.
Happy hacking! |

* Make it possible to switch a placeholder shape into the shape it represents.
There are still some open points maybe someone has an idea: I would like to change the placehoder shape when you double click on it in the default tool.
That already works but it is not nice as the tool used for doing the change pops up in the tool box.
Also I'm not sure which shape is clicked when the placeholder tools is activated.
At the moment I use the first selected placeholder shape. |

* remove compiler warnings in switch() and add FIXME instead for missing chart types
* introduce setUseAutomatic[Minor/Major]Interval() (not a feature - this was possible before, by setting the interval to 0)
* Relayout KDChart plane after switch between logarithmic and linear scaling
* split showGrid() up into showMajorGrid() and showMinorGrid()
* load axis style (code mistakenly was in the wrong place)
* load axis font from ODF
Axis scaling dialog:
* Get initial properties from axis |

Performance improvements for deleting local files.
Deleting 1000 local files (without progress info dialog):
before: 4177 ms with independent jobs, 3860 ms with one job
after: 1010 ms with independent jobs, 150 ms with one job.
End users selecting 1000 files in konqueror fall into the "with one job" category, so this is a 25-times speedup. |

David Faure committed a change to /trunk/KDE/kdelibs/kio/kio/kdirmodel.cpp:
|
Performance: replace linear search with hash-table lookup, so that the O(n*depth) method is now only O(depth)
(but in many cases the caller then calls a O(n) method, so this is O(n) in practice, where n is the number of files in the directory, so no complexity gain in the n=5000 depth==1 case like bug 150885 -- but in practice the remaining O(n) lookup runs much much less code for each iteration than the old code did) |

Guess when the optimisation of "disconnected UI" can be applied and.. apply it!
It really speeds up things when:
- We have no threading / grouping at all
- We're not expanding threads / groups
- We expanding but we're able to guess that the number of expansions will be very low. |

More work on the class browser; I had fixed it up to allow updating from the duchain, but David suggests I re-check the code model in that instance, which sounds like a good idea.
Committing this now (with that path disabled) in case I ever want to retrieve the code.
Also:
- track which files are referenced (by projects, the editor) and show while still referenced.
- cleanups
- remove old duchain-based sorting code
- make the encountered tracking code work on the top node for one specific file at a time
- some documentation (soon to be out of date ;)
- move node class to cpp file (private detail) |

new look and animation for applet handles, based on an old Nuno mockup, that uses the standard applet background (will have new graphics).
also, don't use painter->setOpacity anymore, so should be a bit faster
the look is slightly different in 3 cases:
-the applet is smaller than the handle, the panelsvg gets drawn completely and looks like the old thing
-shape not rectangular: the panelsvg is wider, so it's visible also for instance behind the clock circle
-normal: only a bit of the panelsvg exits from the applet and is visible, the hidden part has a few pixels fade out gradient to look less wrong with transparent backgrounds like folderview or themes with all backgrounds more transparent |

EBN Fixes: Qt classes that should not be used
What does this patch do:
- QComboBox -> KComboBox
- QTabWidget -> KTabWidget
- QLineEdit -> KLineEdit
- QTextEdit -> KTextEdit
- Where KLineEdit is inserted, I explicitly called: setShowClearButton( true )
- Removed in some cases unnecessary includes from header files.
What does this patch not do:
- Fix the ui files
- Fix the QMessageBox -> KMessageBox in kmmessage.cpp I need to have a good look to the KMessageBox API for that.
- Exhaustive cleanup of unnecessary inclusions. |
