  GTK+ Apps Get Free Reign on KDE Technology
Developer Posted by Zack Rusin on Friday 09/Jan/2004, @09:10
from the making-the-impossible-reality dept.
Integration of GTK+ applications in KDE has taken another leap forward. This has historically been a bit of a problem; the fact that Qt and GTK+ rely on different event loops was making it impossible to, for example, use dialogs from one toolkit while building the GUI in another. QtGTK is a library which integrates the Qt event loop in the Glib event loop. This makes it possible to freely use KDE dialogs, DCOP, KDE IO and other KDE technology in any GTK+ application just like they would be native. From now on, every GTK+ application can easily integrate with KDE.

A tutorial explaining how to use this library is available from developer.kde.org. Integrating existing applications is trivial, taking one function call. Just look at what Daniel did with the Beep Media Player (formerly XMMS2):

  1. KDE Directory Open
  2. KDE File Open
The library itself is available in both tar.gz and tar.bz2 format.

This is only the beginning!

Interesting, but not all brilliant
by Tom on Friday 09/Jan/2004, @09:39
This, at first, seems excellent. In theory we could now see lots of GNOME applications, particularly those for which there is no suitable KDE equivalent, integrating nicely with KDE's most important technologies, namely the kio_slaves, DCOP etc.

But one thing worries me: maintenence. Will Beep Media Player need to be patched in every release to make this work, and will someone step up to do this, to provide a KDE version? It seems that if a development team chooses GTK & GNOME, they do it because they want to use those toolkits, and so it will often require outsiders to maintain KDE versions, which could only make things far messier.

Unless, of course, in the future this thing can become standardised so that you select in KControl or some similar place to use KDE widgets in place of Gtk/GNOME ones, and it automatically applies to all applications, without needing any recompiling. But that seems unlikely.

Cool

Cool!

Now if only I could automagically use this for all binary packages of all GTK apps installed on my system... But still, it's great!

Tutorial is a partly unreadable...
by Nadeem Hasan on Friday 09/Jan/2004, @10:06
...due to large black background around the globe near the top. I am using IE6 here, I don't have konqy available here at work ATM to check.

You just rock...
by Debian User on Friday 09/Jan/2004, @10:26
Hi,

this so great. I followed with interest how in context of Sodipodi that was attempted first, and this simple and general solution, great.

Now if somebody commited the patch for GIMP, will they accept it?

And using this new GTK QT theme, would it possible for KDE to offer a button like "start GTK apps with KDE look (not feel)", then it would already be complete.

Yours, Kay

Mozilla and other Qt apps
by Josep on Friday 09/Jan/2004, @11:25
This can also be possible with all the Mozilla familly apps and other Qt apps such as Scribus or Opera and even OpenOffice.org?

This is an excellent notice for KDE users!

Is this C++ only?
by MaxAuthority on Friday 09/Jan/2004, @11:57
Sorry, I am not the best programmer, but the sample code seems like the FileDialogs still are C++ classes.

So how I can I use this in my gtk+ app, when I don't like/want to use C++ but C only?

beep and qtgtk
by David Walser on Friday 09/Jan/2004, @13:21
First, where can I get the patch for beep media player to use this?

Second, I see a qtgtk-0.2 at http://ktown.kde.org/~danimo/

and you linked a qtgtk-0.1.0, which is newer?

Possibilities...
by Cowardly Anonymity on Friday 09/Jan/2004, @13:59
Will KDE eventually be equally usable and integratable from either Qt or GTK+? Will this render the entire Qt v. GTK debate as it pertains to KDE v. GNOME utterly moot?

LGPL license effects
by John on Friday 09/Jan/2004, @14:22
By using KDE dialogs, does it mean that a commercial app developed with Gtk under the LGPL license have to be under the GPL license or otherwise have to buy a license from Trolltech?

So this File Open
by David Oftedal on Saturday 10/Jan/2004, @14:00
So this File Open... Is it simpler to use than its GTK+ 2 equivalent? That's really all that matters to me. I mean, is it so impossible to create a function that just gets a filename and doesn't require you to set up anything else?

foo_api_file_open(target_string,current_directory_string);

Amazing but
by Jose Hernandez on Wednesday 18/Aug/2004, @18:47
Are these pics real?
I am on a quest to find a single patch for QtGtk for popular GTK apps and have yet to find any. I began patching Gimp2 myself but have run into so many problems, I'm not sure I'll continue to try, as I have other priorities.

This is great, but where are the working patches?
