Qt Becomes LGPL
Aequo writes "Qt, the highly polished, well documented, modern GUI toolkit owned by Nokia, will be available under the LGPL starting with version 4.5! It was previously only mainly available under the GPL and a commercial license. Selling licenses was an important part of Qt under Trolltech as it was the company's main source of income, but Trolltech is a fruit-fly compared to Nokia, who want to encourage and stimulate the use of Qt Everywhere [PDF]. This is fantastic news for all commercial developers looking to create cross-platform applications without the need to buy a $4950 multi-platform license per developer."
Over the years I have said many times that TrollTech should have lowered their prices considering things like the Apple Developer's kit and MSDN are significantly cheaper for more functionality.
I have been in need of a good GUI toolkit for years. I have used just about all of them but for my own projects I either use the native toolkit of the OS I'm working on or FLTK for cross-platform stuff. Qt is much more functional than FLTK though with all their SQL and other utility classes. This is really cool. I bet Qt is now going to become the defacto GUI toolkit for everything.
I wonder how long until someone makes a Qt version of GNOME (ha, I can't imagine how much work that would take). You could start with making a Qt version of The GIMP.
Since GNOME is currently brainstorming over how to make GNOME 3, I'd say this announcement come right on time.
Let's focus on the applications and not on reinventing the wheel.
The toolkit feud has gone on for far too long. Let's share a common toolkit. GNOME is using more Vala and C#/Mono these days and Vala/C#/Mono on top of Qt would make gnomies very happy I think.
Re-implementing GNOME on top of Qt with the traditional focus on HIG should not be all that hard.
This is an exiting opportunity for GNOME. I wonder if they'll embrace it and make the Linux desktop go forward.
"if you avoid using programs from another desktop"
Which is just not possible. Where is the CD burning program in GNOME that beats K3B? Where is the music player that beats Amarok? In the other direction, where is the office suite that beats OpenOffice.org? You cannot avoid mixing GTK and Qt apps on a desktop without hurting yourself.
"Honestly, I have no trouble using mixed apps on the same desktop."
Just three days ago at FUDCon, I saw someone try to use KGPG on their GNOME desktop. He had localized GNOME in Dutch, and when KGPG pops up...everything was in English. The localization settings are stored in different places, which is a problem that goes beyond "installing themes to make it look the same." There is also the failure to have OLE across Qt and GTK, which has so far only been solved by disparate hacks in specific applications, and only works for certain cases. The copy and paste problems being solved was a good thing, but that is only one of many issues that arise from mixing GTK and Qt apps on a single system.
Palm trees and 8
I have a hunch Nokia is looking at XCode and Apple instead. After all, the main battle for them is in the mobile market, and Apple made a big deal about the iPhone being based on OS X. So this is a bid to win over the talented developers.
QT is available on more platforms, true, and it always has been. Still, XCode was free for anyone with a Mac, and the developer kits for the iPhone only required that you own a Mac and that you registered as a developer.
That is the chance and duty of freedesktop.org. Combining the parts that are common and the platforms can agree upon. Defining the standards (like trash, cache, drag+drop, etc.).
It is getting better and better (e.g. I think KDE+GNOME both use DBUS now? ), some services/libs (NetworkManager) are already commonly used.
What I'd really like to see is a common password storage.
