This document contains the changes you have to apply to programs written for
|
|
|
|
|
|
KDE1.1 when you want to port them to KDE2.0.<P>
|
|
|
|
|
|
|
|
|
|
|
|
As a start you should have a look at doc/porting.doc in the Qt package,
|
|
|
|
|
|
or <a href="http://doc.trolltech.com/porting.html">this page online</a>.<P>

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.tdevelop.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.

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>&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>

|
|

|
|
|
|
|
|
|
|
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 It has been replaced by am_edit which provides a lot of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-<appname>.png), and install
|
|
|
|
|
|
the application-specific icons under $(kde_datadir)/<appname>/pics.

<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->getIconLoader()->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()->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 KMainWindow. aboutKDE(), aboutApp() and
|
|
|
|
|
|
appHelpActivated() have all been removed See section for KMainWindow
|
|
|
|
|
|
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>
|

<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.
|
|
|
|
|
|

TDEApplication::getApplication()->getLocale()->translate<P>

|
|
|
|
|
|
|
|
|
|
|
|
KIconLoader 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>

"kapp->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>

access to a help menu in a class that is not derived from

KMainWindow then allocate an instance of the new class KHelpMenu.

|
|
|
|
|
|
|
|
|
|
|
|
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<EFBFBD>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.
|
|
|
|
|

|

<LI>tdehtml uses QString's instead of char *'s now. This means, that most

The new KIntNumInput can have an optional slider attached, ensures

that the entered value is in a given range (use MAX_INT or similar

label and also a unit for the edited value.<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>

|
|
|

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

method if you wish.<P>

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 &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>

this:<P>

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

vanished, since support for it moved to Qt.<P>
|
|

|
|

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
|
|
|
|
|
|
listbox, a listview and multi line editor, you would do something like
|
|
|
|
|
|
this:<P>
|
|
|
|
|
|
<TABLE><TR><TD>
|
|
|

TQSplitter *split = new TQSplitter( parent );<BR>

TQListBox *lb = new TQListBox( split );<BR>
|
|
|

KListView *lv = new KListView( split );<BR>
|

</TD></TR></TABLE>
|

|
|

|
|
|
|
As you can see you are not limited to two children. Additionally, you
|
|
|
|
|
|
do not have to call activate when you are done, and opaque resizing is
|
|
|
|
|
|
possible if you call setOpaqueResize(true).<P>

Use KListView, TQListViewItem instead. API is almost the same, you only
|
|
|
|
|
|
need to add a Column (KListView::addColum) before KListView is useable.<P>
|
|
|
|
|
|
|
|
|
|
|
|
KListView has no addChild(), insertItem() and removeItem() calls. Inserting
|
|
|
|
|
|
a root item is done by constructing a TQListViewItem with the KListView
|
|
|
|
|
|
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 <pointer to item>.<P>
|
|
|
|
|
|
|
|
|
|
|
|
The root items are not shown in a tree fashion by default. to get this,
|
|
|
|
|
|
use KListView::setDecorativeRoot(true).<P>
|
|
|
|
|
|
|
|
|
|
|
|
Expanding and collapsing can by done by using TQListViewItem::setOpen(bool).<P>

The KWMModuleApplication has been removed. Instead, use the class
|
|
|
|
|
|
KWinModule in libtdecore. The API is a bit cleaner but very similar,
|
|
|
|
|
|
so you will feel comfortable immediately. One of the advantages of
|
|
|
|
|
|
KWinModule is that it doesn't require a special TDEApplication
|
|
|
|
|
|
subclass. This lead to many problems and misunderstandings in the
|
|
|
|
|
|
past. KWinModule is now just an object that emits fancy signals (and
|
|
|
|
|
|
provides some useful lists, like the list of all managed windows).

|

|
Use kdDebug, kdWarning, kdError, kdFatal to log debug output, warnings and
|
|
|
|
|
|
errors in a very flexible way. kdebug has been improved, and the API simplified.
|
|
|
|
|
|
tdesdk/scripts/kDebug2kdDebug.sh provides a script for automating the conversion.
|
|
|
|
|
|
Note that enabling/disabling debug output can now be done with kdebugdialog,
|
|
|
|
|
|
which can be found in tdebase. The hidden dialog on C+S+F12 no longer exists.
|
|
|
|
|
|
<P>
|
|
|
|
|
|
Also, note that tqDebug and fprintf aren't disabled by -DNDEBUG, whereas kdDebug is.
|
|
|
|
|
|
One more reason to use kdDebug !

The new (rewritten) KFileDialog (KFD) is a lot more like the new QFileDialog
|
|
|
|
|
|
but still looks quite different. Normally you may want to use the static
|
|
|
|
|
|
methods provided for convenience (getOpenFileName and getSaveFileName).
|
|
|
|
|
|
If you need special features you can configure the dialog extensively. Just
|
|
|
|
|
|
create an object and use the different methods. <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 &))
|
|
|
|
|
|
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.
|
|
|
|
|
|
<p>
|
|
|
|
|
|
<ul>
|
|
|
|
|
|
<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
|
|
|
|
|
|
<p>
|
|
|
|
|
|
If you are writing "real multimedia apps", you may also have a look at the
|
|
|
|
|
|
even more advanced sound/multimedia support, that using the aRts/MCOP
|
|
|
|
|
|
libraries directly can offer you.
