| Qt 4 Preview 2 Highlights Accessibility; D-BUS Bindings for Qt 4 |
 Posted by binner & harry on Thursday 23/Sep/2004, @11:28
from the accessible-and-connected dept.
Trolltech has announced the availability of the second Qt 4 Technical Preview. Key highlights include support for AT-SPI, bringing accessibility to the Unix and Linux desktop for people with disabilities. Read the online documentation or jump to the download page.
Together with this tech preview, Harald Fernengel released a preview of a brand new set of D-BUS bindings. Using Qt's meta object system, broadcasting signals and invoking methods in other applications is now a breeze. D-BUS signals can be connected to any slot. No preprocessor and no special wrapper classes are necessary. You can download the library at the Qt D-BUS tutorial page.

Amazing speed of Development
by Debian User on Thursday 23/Sep/2004, @13:34

It's amazing at what speed Qt is being developed.
I dare say, that apart being premier choice on Linux already, with say QT 4.2, there will complete breakthrough making Qt and KDE the de facto standard for new apps.
Yours, Kay

docs
by aleXXX on Thursday 23/Sep/2004, @13:43
|
I just had a look at the Qt4 docs, what I'm still missing is a separation in the docs by the libraries, i.e. Qt Core docs, Qt GUI docs etc.
Bye
Alex

Nice!

Judging from the DBUS Qt4 tutorial, it looks like that API is a LOT cleaner than than the dbus-C api. I'll have to say that Trolltech does a wonderful job in designing sane API's.

DCOP
by AC on Thursday 23/Sep/2004, @14:35

DCOP was part of KDE, not Qt... Since there is a replacement in Qt now, will DCOP be going away? Or is this not really a replacement?

KJSEmbed for Qt4
by Richard Moore on Thursday 23/Sep/2004, @14:37
|
I hope to port the standalone version of KJSEmbed (QJSEmbed) to the technology preview in the next few weeks. That should give us an idea of how hard is to port code that is intimately tied to the internals of Qt to the new release. My initial investigations with the first preview indicate that this should be possible with a minimum of pain.

D-BUS replaces Bonobo?
by ac on Thursday 23/Sep/2004, @14:41

You missed some important news:
http://trolls.troll.no/~harald/accessibility/
I don't understand too well but it looks like there is now a way to replace Bonobo with D-BUS in AT-SPI/ATK stuff? This is great news! I wonder how Sun/GNOME will react to that.

New signals and slots features
by Richard Dale on Friday 24/Sep/2004, @03:24
|
I think you can now connect signals and slots across threads, and you can either emit signals synchronously as now, or asynchronously. Nice. I looked at the online docs, but it doesn't seem to have been written up yet. Connect now looks like this:
bool QObject::connect ( const QObject * sender, const char * signal, const QObject * receiver, const char * member, Qt::ConnectionType type = Qt::AutoConnection )
So I assume you describe the signal behaviour with different values of the Qt::ConnectionType enum.
