1 This file is meant to be a place to track of medium to large-scale API changes
2 that we would like to make for the next binary incompatible release.
4 - Check for forked classes in kde pim and other modules
7 - Make KSystemTray add its own reference to KApp, so tray apps that adhere to the
8 style guide can safely close their main window without having to worry about
9 the app quitting instead.
12 - Sort out reference counting of applications and KMainWindows: Add a setRefCountEnabled()
13 function to KApplication; deref()ing the last reference should only quit the application
14 if reference counts are enabled, and the reference count should be disabled by default
15 so apps that don't use a KMainWindow mostly continue to work. Make the KMainWindow
16 constructor call setRefCountEnabled(true), and make each KMainWindow hold its own
17 reference to the application. The KMainWindow should drop its app reference on hide, and
20 Make KSysTray also hold a reference to the app. Then apps that use more than one main
21 window and the tray (like KSIrc and Kopete) will quit at the right time without nasty
25 - Make some long-lasting operations threaded. There are some operations in KDE that
26 take too long on at least ~500MHz hardware to be done using event loops. Examples
27 are the use of KLibLoader to dlopen plugins and KRun to fire up other processes.
28 Konqueror and KMail tend to stall occasionally too, but that's harder to refactor
29 because the bulk of the work there is X11-related.
32 - Make it possible to use SSL-ed sockets outside KIO. KSSL isn't very suitable for
33 reuse, and the certificate dialogs are not even available in public API at all,
34 leading e.g. to Kopete IRC duplicating a lot of stuff and all KDE Jabber clients
35 based on libpsi (PSI, Light Hawk and Kopete) using homebrewn solutions. [How
36 does this have to do with changing KIO? It's just a request to have that
37 code in a different form....]
40 - Solve need for casting when using bitfield enums (e.g. K3Process::Communication)
41 by the use of Q_DECLARE_FLAGS/Q_DECLARE_OPERATORS_FOR_FLAGS
44 - KParts: remove plugin loading from setInstance, add an explicit loadPlugins() call
45 in all parts that should load plugins (at the end of the derived-part ctor).
48 - KParts: come up with better names for ReadOnlyPart and ReadWritePart, ReadOnly
49 is a minimum requirement, but this does not become clear until you dig deeper
50 into the class. With QTextEdit and QTextBrowser for instance, the inheritance is
51 the other way around. E.g.: ReaderPart? ViewerPart?
54 - Change classes that store bool data using strings ("true"/"false") to use bool
55 calls (readBoolEntry()). Although not technicaly a binary incompatiblity...
56 just something to bring up for possible change (for the better)
58 Use KConfigXT instead! /FransE
60 - Is it really necessary to bother people using the KCM APIs with withFallback? I have
61 never heard of it failing and when would you not like to have that fallback? I think
62 a default of 'true' would be fine(and remove the argument in the APIs).
65 - Do we need to have factory arguments in the KCM API? (who would use it anyway?)
68 - The config options in kdeglobals needs to be cleaned up a little. Perhaps I'm being picky..
69 * They should be named properly, for example "enableIcons" instead of "EnableIcons". Or atleast
71 * AFAICT it would be the right thing if KWin had its own rc file instead of having its "WM"
72 section in kdeglobals.
73 * Shouldn't Sonnet have its own rc file instead of kdeglobals?
74 * Should we allow spaces in option names?
75 * Some option names are too short for being understandable. fixed->fixedFont; font->systemWideFont
76 * Perhaps an own font section?
79 - Make functions in KHelpMenu virtual so they can be overridden (ex: to provide
80 an alternative help->contents action)
83 - Make sure all GUI classes adopt well to palette changes.
86 - K3ListView lacked a setDnDMode to choose between "dnd to move items" (e.g. keditbookmarks)
87 and "dnd onto items" (e.g. kmail). Check how to do this with QListView/QTreeView...
90 - Add the concept of a session to KIO, in particular for KHTML so that it can
91 have all of its jobs associated in some way (a unique key of sorts). Will
92 make SSL much easier to implement and allow removal of many hacks, mostly
96 - Make KLibLoader default to RTLD_GLOBAL and make necessary changes to make KDE namespace clean.
98 Maybe just make sure we don't emit multiple copies of per-class data (vtable,RTTI), then
99 RTLD_LOCAL should do as well, and it should(?) be simpler this way.
102 - Many instances of creating containers on the heap instead of stack, can be replaced? (Caleb Tennis) [where?]
104 - Add KAssistant - a new KDE standards-compliant wizard, (Jaroslaw Staniek (TODO/KAssistant|Details))
105 Qt4 has no QWizard (only Q3Wizard left). Add a new KDE standards-compliant wizard with
106 a bit more powerful API and features like "Steps list" pane on the left hand of the wizard
107 (user can click any step if developer allowed such action). Example from OO.org:
108 http://www.openoffice.org/dev_docs/features/2.0/images/mail_merge.jpg
109 We could add more consistency (using themes, guidelines) in this area,
110 as in KDE3 some apps implement wizard's features like left-hand funky pictures
111 or help text again and again
112 (see http://www.kolab.org/doc/kde-client-manual-0.9cvs20030801-html/c43.html).
114 * use nonintrusive "watermark" effect on the 1st or all pages
115 (http://images.apple.com/macosx/features/setup/images/index_setup20050412.jpg),
116 * allow to disable steps on the left-side list as an answer to calling setAppropriate().
117 * QWizard's API is mostly ok for the new class, just avoid requiring to pass a pointer
118 to page widget (as in setAppropriate()) but allow to pass QString names or IDs instead.
121 - K3IconView/K3ListView equivalents based on Qt4 interview. As discussed on kde-core-devel,
122 this probably means a custom QItemDelegate instead, to handle single-click/double-click,
123 execute-mode/select-mode (cf K3IconView), number of lines used for wrapping, "held" signal.
124 In short, rewriting k3iconview features to be based on interview.
125 For K3ListView we need to check if QTreeView supports both modes of drag-n-drop (dropping
126 onto items, and dropping between items like in the bookmark editor).
130 * install /share/apps/ksgmltools2/customization/entities/kde-standard-accels.entities
131 * win32: fix path delimiter problem generated *.bat wrapper (using ' ' instead of ';')
133 - It looks like most of the functions KStringHandler can be removed. At least, insword, setword,
134 remrange, and remword could be removed [DONE] . Those four don't seem to be used anywhere inside of KDE. Other
135 functions like capitalize and reverse seem to be sparsely used.
138 - Prevent re-entering event loop in kded to avoid reentrancy problems like with kwallet in KDE3 (Lubos).
140 - Customizable KToolTip/KWhatsThis widgets (Jaroslaw Staniek),
141 now KWhatsThis is a part of KDE GSoC "Implement OpenUsability's Context Sensitive
142 Help Redesign" project, by Joshua Keel, mentored by Ellen Reitmayr

146 - Additional (automatic) shortcuts for KMessageBox (Jaroslaw Staniek)
