-
- The first step to get your KDE application to compile under KDE 2.0,
- is to detect KDE 2.0 and Qt 2.x at configure time. The easiest way to
- get a working autoconf/automake framework, is to either use
- <a href="http://www.kdevelop.org">KDevelop</a> or
- <a href="http://home.earthlink.net/~granroth/kapptemplate/index.html">kapptemplate</a>
- (available in CVS under the module "tdesdk"), to generate a new
- application template. Replace the generated source files by yours
- and adapt Makefile.am accordingly.
-
-<H4><P ALIGN="RIGHT"><A HREF="#TOC">Return to the Table of Contents</A></P></H4>
-
-<H3><A NAME="general">Global changes</A></H3>
-
- We did our best to clean up the header files of tdelibs, so they do
- not include unnecessary bloat for your application. As a consequence, you
- may notice that some header files are missing from your source files as
- they have been included before by kapp.h for example. There is a script
- in tdesdk/scripts called "fixheaders" that takes care of most of these
- cases. Just call "make -k 2&gt;&amp;1 | perl .../fixheaders" and it will try
- to look after the error messages and add includes as it recognize the
- errors.<P>
-
- Also, if your code does not compile and complains about missing member
- functions, you should check for methods that started with get...().
- These methods have been renamed to xy*() for consistency.<P>
-
-<H4><P ALIGN="RIGHT"><A HREF="#TOC">Return to the Table of Contents</A></P></H4>
-
-<H3><A NAME="automoc">automoc/am_edit, Makefile.am tags</A></H3>
-
- On the subject of the compilation framework, automoc has been removed from
- the admin directory. It has been replaced by am_edit which provides a lot of
- additional features.<P>
- METASOURCES=AUTO still does the job of generating the appropriate moc files,
- but in addition, you should use KDE_ICON for the icons representing the application
- (and naming those icons conforming to lo16-app-&lt;appname&gt;.png), and install
- the application-specific icons under $(kde_datadir)/&lt;appname&gt;/pics.
-
-<H4><P ALIGN="RIGHT"><A HREF="#TOC">Return to the Table of Contents</A></P></H4>
-
-<H3><A NAME="TDEApplication">TDEApplication</A></H3>
-
- doesn't hold any longer a TDELocale instance. With this getLocale()
- and isLocaleInstantiated are now replaced by TDEGlobal::locale()<P>
-
- it also doesn't hold a KiconLoader instance. As this also getIconLoader()
- has been removed. Replace kapp-&gt;getIconLoader()-&gt;loadIcon() with
- BarIcon() or use TDEGlobal::iconLoader() instead of getIconLoader()<P>
-
- kde_*dir() have been removed as they require a unique top level directory
- for all applications (TDEDIR). This concept doesn't exist in KDE 2.0
- any more, it has been replaced with "multiple levels of directories",
- set in TDEDIRS, so that it's possible to have global settings and
- group settings, applied before user settings.<P>
-
- Replace code that uses kde_*dir() + filename with calls to
- locate(filetype, filename) where filetype is what * used to be
- in kde_*dir(). locate is defined as function in kstddirs.h to call
- TDEGlobal::dirs()-&gt;findResource.<P>
-
- Use locateLocal to get the path of a writable file. For instance,
- TDEApplication::localconfigdir()+filename is now locateLocal( "config", filename ),
- but for most cases, simply using TDEGlobal::config() is enough, if you're happy
- with saving the application's configuration into appnamerc, or
- KSimpleConfig cfg("anothercfgfile") to create a config file with another name.<P>
-
- generalFont() and fixedFont() are deprecated and will be removed soon.
- Please use TDEGlobalSettings::generalFont() and TDEGlobalSettings::fixedFont() instead.<P>
-
- appName() is deprecated. Please use TQApplication::name() or instanceName
- instead.<P>
-
- The methods tempSaveName() and checkRecoverFile() return QString
- now. The returned values must _not_ be free()d.<P>
-
- helpMenu() has been moved to TDEMainWindow. aboutKDE(), aboutApp() and
- appHelpActivated() have all been removed See section for TDEMainWindow
- for more info.<P>
-
- The TDEApplication constructor has changed. Command line arguments and
- program name should no longer be passed to TDEApplication but to
- TDECmdLineArgs. TDECmdLineArgs performs command line parsing and a command
- line help. See below for more info.<P>
-
-<H4><P ALIGN="RIGHT"><A HREF="#TOC">Return to the Table of Contents</A></P></H4>
-
-<H3><A NAME="TDECmdLineArgs">TDECmdLineArgs</A></H3>
-
- TDECmdLineArgs is a new class that handles command line parsing and
- command line help. It is now required that your application
- specifies at least:<P>
- <UL>
- <LI>Its name.
- <LI>A short description what it does. (e.g. 1 line)
- <LI>A version.
- <LI>All command line options that it supports.
- </UL>
-
- TDECmdLineArgs itself will add the command line options supported by Qt
- and TDEApplication.<P>
-
- You can also use the TDEAboutData class to specify name, description and
- version.<P>
-
- In return for this information you can query TDECmdLineArgs whether an
- certain option was specified on the command line and your application
- now automatically supports --help and --version. It aborts with a
- useful error message when the command line contains a syntax error.
- See tdelibs/tdecore/tdecmdlineargs.h for more info.<P>

-
- i18n is no longer a macro<P>
-
- TDEApplication::getApplication()-&gt;getLocale()-&gt;translate<P>
-
- but a function on its own. klocale is obsolete and replace every call
- to klocale-&gt;translate with i18n.<P>
-
- The return value of i18n is also no longer a const char*,
- but a unicode TQString.<P>

-<H4><P ALIGN="RIGHT"><A HREF="#TOC">Return to the Table of Contents</A></P></H4>
-
-<H3><A NAME="TDEGlobal">TDEGlobal: access to KDE global objects.</A></H3>
-
-TDEGlobal allows centralized access to KDE global objects without including
-extraneous headers. object creation is deferred if possible.<P>
-
-All methods are static and headers for returned types are not included. You
-must have created a TDEApplication object before the methods can be used.<P>

-
-TDEIconLoader in 1.1 used to mix icons for applications and for toolbars.
-This has changed, so you may notice that your application doesn't find
-the right icons. loadIcon (used by BarIcon) returns only toolbar icons.<P>
-If you need icons for applications, use loadApplicationIcon.<P>
-loadMiniIcon and loadApplicationMiniIcon have been removed, instead
-loadApplicationIcon now takes a "size" argument where you can specify the
-size of the icon (small, medium, large).<P>
-The other big change you may notice, is that ICON and Icon have been
-removed as they caused big confusion for not loading application icons
-(see above). For this we added BarIcon which does the same as ICON before.
-The third change in this row is that loadIcon doesn't need the extension
-anymore, but looks for standard extensions (png, xpm) itself. If you hard-
-coded .xpm, loadIcon will issue a warning at runtime, but will still work
-in stripping off the .xpm part<P>

-<H3><A NAME="KTMainWindow">KTMainWindow</A></H3>
-
-KTMainWindow has been replaced with TDEMainWindow.<p>
-
-The TDEMainWindow constructor needs a parent widget as first argument.
-You can use 0 for this.<p>
-setView() has been replaced with setCentralWidget().<p>
-view() has been replaced with centralWidget().<p>
-addToolBar() has been removed, it is not needed any more.<p>
-setMenu(...) has been removed, it is not needed any more.<p>
-setStatusBar(...) has been removed, it is not needed any more.<p>
-updateRects() has been removed, it is not needed any more.<p>
-enableStatusBar(...) has been removed, use statusBar()-&gt;show() and/or
-statusBar()-&gt;hide() instead.<p>
-enableToolBar(...) has been removed, use toolBar()-&gt;show() and/or
-toolBar()-&gt;hide() instead. <p>
-
-view_* public variables do no longer exist. There is really no reason
-for an app to use this information. If you do need it anyway, use
-mainViewGeometry() instead.<P>
-
-<H4><P ALIGN="RIGHT"><A HREF="#TOC">Return to the Table of Contents</A></P></H4>
-
-<H3><A NAME="KHelpMenu">KHelpMenu</A></H3>
-
-helpMenu() has been moved to TDEMainWindow from TDEApplication (kapp).<P>
-
-Both the "About KDE" and the "About &lt;Application&gt;" dialog boxes
-are now modeless. "About KDE" is a completely new widget.<P>
-
-If you used in the toplevel window (that is derived from TDEMainWindow)
-"kapp-&gt;helpMenu( bool, TQString )" to get the help menu
-you must now change this to "helpMenu( TQString )". The TQString defaults
-to TQString::null so it is sufficient to write helpMenu().<P>
-
-The old aboutKDE(), aboutApp() and appHelpActivated() of TDEApplication
-have all been removed. If you need direct access to these or need
-access to a help menu in a class that is not derived from
-TDEMainWindow then allocate an instance of the new class KHelpMenu.
-See KDE 2.0 API reference or khelpmenu.h (tdeui) for additional info.<P>

-<H3><A NAME="launching">Starting other programs</A></H3>
-
-In KDE 2.0 there are several ways to start other programs from within
-your application. Here is a short summary of your options with reasons why
-you should or should not use them.
-<H4>1. fork + exec</H4>
-<P>
-You never want to use this unless you have a very good reason why it is
-impossible to use TDEProcess.
-</P>
-<H4>2. TDEProcess</H4>
-<P>
-You want to use this if you need to start a new process which needs to be a
-child of your process, e.g. because you want to catch stdout/stderr or need
-to send it data via stdin. You should never use this to start other KDE
-applications unless your application is called kgdb :-) If you need to
-send/receive text like data to/from the process, you are probably better
-off with KProcIO
-</P>
-
-<H4>3. KProcIO</H4>
-<P>
-Like TDEProcess. Unlike TDEProcess, this class actually makes it easy to
-send data to and receive data from the process.
-
-</P>
-<H4>4. startServiceByDesktopPath</H4>
-<P>
-Preferred way to launch desktop (KDE/Gnome/X) applications or KDE services.
-The application/service must have a .desktop file. It will make use of
-KDEinit for increased startup performance and lower memory usage. These
-benefits only apply to applications available as KDEinit loadable module (KLM)
-</P>
-<H4>5. KRun</H4>
-<P>
-Generic way to open documents/applications/shell commands. Uses
-startServiceBy.... where applicable. Offers the additional
-benefit of startup-notification.<BR>
-KRun can start any application, from the binary or the desktop file,
-it will determine the mimetype of a file before running the
-preferred handler for it, and it can also start shell commands.
-This makes KRun the recommended way to run another program in KDE 2.

-
-tdehtmlw has been replaced with tdehtml.<BR>
-<UL>
- <LI>TDEHTMLView has vanished. Just use TDEHTMLWidget, which does scrollbar
- managing for free.
-
- <LI>A lot of the API has changed. If you just want to open a file/URL,
- you just need to do:<P>
- <PRE>
- TDEHTMLWidget *w = new TDEHTMLWidget();
- w-&gt;openURL(myURL);
- </PRE>
-
- <LI>tdehtml uses QString's instead of char *'s now. This means, that most

- TQStrList -&gt; QStringList

-
- KIntegerLine and KIntLineEdit have been replaced by KIntNumInput.
- The new header file is called knuminput.h.<P>
-
- The new KIntNumInput can have an optional slider attached, ensures
- that the entered value is in a given range (use MAX_INT or similar
- if you don't care about the range) and can maintain a descriptive
- label and also a unit for the edited value.<P>
-
- The API is almost the same and it simplifies existing code a bit,
- so give it a try. If you need more functionality, please contact
- me, Dirk A. Mueller &lt;<A HREF="mailto:mueller@kde.org">mueller@kde.org</A>&gt;.<P>

-
-KDE Drag and Drop is Dead. Long live Qt Xdnd.<P>
-
-Xdnd is better anyway, because it has been adopted by all the other
-major GUI toolkits still under active development (this precludes
-Motif, but maybe we can convince the lesstif guys!). Some changes
-are necessary to convert your old KDND-based stuff to Qt DND.<P>
-<UL>
-<LI>Remove drag.h from all of your sources / header files.<P>
-<LI>Remove KDNDDropZone object creations. Instead of creating an
- object of this type and then connecting it to some arbitrary slot
- to handle drops, call "setAcceptDrops(true)" in your widget
- constructor and then override the protected methods dragEnterEvent,
- dragMoveEvent, dragLeaveEvent, and dropEvent.<P>
-<LI>You should be aware that to handle drops, you will either have to
- inherit a widget and then override the methods mentioned above,
- or install an event handler for the widget in that widget's parent,
- and then handle TQEvent::DragMove or TQEvent::Drop inside there (if
- you want to avoid inheritance).<P>
-<LI>You can emulate the old DndURL drop-type behavior with the Qt
- Drag Object type QUriList.<P>
-<LI>You can start a drag from inside your widget's mouseMoveEvent
- method if you wish.<P>
-<LI>Qt includes a Drag and Drop tutorial. We suggest you read that
- now if you are confused.<P>
-<LI>TQMultiLineEdit has already a DnD interface that accepts text/*
- If you want to add support for other mimetypes, you need to
- re-implement all DnD-methods (also dragMoveEvent()) and pass
- QTextDrag's to the parent methods.<P>
-<LI>TQTextDrag also accepts text/uri-list, which means that you
- always need to check for TQUriDrag first if you want to get
- both working.<P>
-<LI>The mimetype for Uri's is now text/uri-list. If you've used
- the proprietary Qt 1.x url/url, you need to adjust that.

-
- These classes have been largely re-implemented. The external API
- remains mostly the same, with the single notable change that
- the groupIterator and entryIterator methods have been removed and
- instead replaced by groupList (which returns a TQStringList of groups)
- and entryMap(const TQString &amp;group) (which returns a TQMap of entries
- in the specified group). This is due to internal changes in TDEConfig
- which would make providing iterators possibly rather difficult.<P>
-
- Much more extensive documentation on the TDEConfig and friends API can
- be found in the kdoc generated documentation from the header files,
- and in tdecore/KCONFIG_DESIGN.<P>
-
- To use the new iterator, you will probably want to do something like
- this:<P>
- <PRE>
-
- TQMap&lt;TQString, TQString&gt; tmpMap = config-&lt;entryMap(myGroup);
- TQMap&lt;TQString, TQString&gt;::Iterator aIt(tmpMap.begin());

-
-The kcharsets class has been completely rewritten, and most of it has

-
-Most applications will only need to replace kapp-&gt;getKCharsets() with
-TDEGlobal::charsets().<P>
-
-For conversion of various input formats to QStrings, please have a
-look at TQTextCodec and classes derived from it.<P>
-
-Character entities are now converted from and to QChars. The name has
-changed from convertTag to fromEntity and toEntity.<P>
-
-To get a font, which can display a certain charset (if such a font
-exists), you can use the KCharsets::setQFont methods. Input is a font and
-a charset. Kcharsets tries to find an output font, which matches the
-input font most closely, but can display the given charset.<P>

-KPanner and KNewPanner have been removed. TQSplitter does everything
-KPanner did and more. The api is similar, but not compatible.
-Basically to set it up so that you have a vertical splitter between a

-
-Use TDEListView, TQListViewItem instead. API is almost the same, you only

-
-TDEListView has no addChild(), insertItem() and removeItem() calls. Inserting
-a root item is done by constructing a TQListViewItem with the TDEListView
-passed as the parent widget. adding a child item is done by constructing
-a TQListViewItem with the parent item as parameter. removeItem() should
-be replaced by delete &lt;pointer to item&gt;.<P>
-
-The root items are not shown in a tree fashion by default. to get this,
-use TDEListView::setDecorativeRoot(true).<P>
-
-Expanding and collapsing can by done by using TQListViewItem::setOpen(bool).<P>

-There is also a new preview mode which is quite different to the one we had in
-the KDE 1.x KFD. There are no preview modules you have to register but there
-is a single method you can use to set a preview widget. This widget has to
-inherit TQWidget and you have to implement a slot (showPreview(const KURL &amp;))
-in this class. This slot is called each time the selected file/dir changes.
-In this slot you have to react appropriate (i.e. show the preview :). The
-easiest way this can be done is to derive your class from TQWidgetStack and
-add a Object (derived from TQWidget) for each file type. In the showPreview
-method you just raise the matching widget. If you can't find an appropriate
-widget just hide() the widget stack.<P>
-If you need some "inspiration" on how that could be done, please have a look
-at koffice/lib/kofficecore/koFilterManager.cc (PreviewStack).<P>

-The KAudio class no longer exists. Here are your options for porting.

-<li>notifications like "you have got new mail"
-<p>
-The way to go for this one is to use the KNotify API, which will allow
-users to reconfigure how your application should sound. On the other hand,
-they will also be able to disable specific sounds, rather let the events
-log to a file, and so on. You can provide an rc file with the default
-configuration. (Include "knotifyclient.h" and use the KNotifyClient class).
-<p>
-<li>very simple cases
-<p>
-On the other hand, if you just want a really small solution, there is the
-KAudioPlayer class (declared kaudioplayer.h), which has a static member
-function for playing, like
-<p>
-<pre>
- KAudioPlayer::play("/var/samples/foo.wav");
-</pre>
-<p>
-<li>multimedia apps

-libraries directly can offer you.
