OS/2 and eComStation For some months now, independent developers have been working on a Qt4 port for eComStation, and it's almost ready. Some Qt4 applications have been ported to eCS, as well. This project is funded by donations from the eCS-OS2 community and currently they have 82% of the needed sum.

I'm not a programmer but correct me if i'm wrong: qt is going to be the next java write once, run everywhere.

While I like Qt I highly disagree with that statement. Qt is a library/framework, Java is a bytecode compiled JITed language. Totally different things! After all there are Java Bindings for Qt, so how could Qt be a replacement for Java? Also Javas main field of application is servers (J2EE). To use a lowlevel language like C/C++ there would just be insane. Also thats not the target of Qt.

For good reason - all Java GUI toolkits are unacceptably slow and huge memory hogs! Somehow neither Sun, nor anybody else could resolve these two problems - so Java is stuck with J2EE type apps, or mickey mouse mobile device (phone) applications.

You are wrong.

This is not "writeonce, run everywhere". It is more correct to view it as "write once, compile everywhere" - which makes it similar to all the other frameworks available (GTK+ (don't forget lazarus), VCF, WinForms (through mono)).

AFAIK Java is the platform to run apps, while QT seens to be the framework/set of GUIsh tools

Yes and No. Java is more than just a virtual machine, it has a huge class library that contains from parsers, to networking to database access etc.

Same goes for Qt. Qt might have started as only a GUI toolkit, but now it contains much more, like 2D and 3D libraries, Networking, Multi-threading and database classes.

But the big difference is that Qt based apps are native apps (no virtual machine required), so tend to be faster, use less memory etc. than Java equivalents.

I know about Qt, but don't do programming in C/C++ language. I can say that Free Pascal (FPC) and Lazarus has already beat Qt - based on your statement (platform count supported). FPC & Lazarus's slogan is: "Write once, compiler everywhere". FPC is a Object Pascal compiler that supports 15+ platforms and chip architectures, and Lazarus LCL framework supports GTK1, GTK2, Qt4, Mac OS X Carbon, Windows Mobile and Embedded Linux devices. All without the need to change your code, simply recompile your existing code for the target platform. Very cool!

FPC: http://www.freepascal.org
Lazarus: http://lazarus.freepascal.org

Oh, and Object Pascal is so much easier to learn and write than C/C++, yet just as powerful and fast.

Do you really beleave what you say?

Lazarus is horrible. It is totally unstable the LCL is totally unintegrated in any os.(using a toolkit does not make it look native) A lot parts are buggy resource hungry and practiclly unusable. The IDE is not nearly on the level of QtCreator or Eclipse.

And Object Pascal is not the language everyone want.

My experience was that it is better to use a combination like C++/Python and Qt or Python and pyGTK rather than Object Pascal and the LCL.

Seeing Qt4 being ported to so many platforms (eComStation, Haiku...) is really nice! I have always had a special interest for the Free Pascal Compiler and for Lazarus, but ultimately I decided to switch to Qt4/C++ programming for doing serious work. The biggest problems I see with FPC/Lazarus are:

(1) the documentation for the many FPC/Lazarus libraries is nothing like the one provided by Qt. Sure, there is a lot of documentation around, but either it is lacking, or it is really sparse. (I have spent a lot of time trying to find a good example for the Sqlite3 unit some time ago!) Qt provides everything in one easy-to-access place (QtAssistant).

(2) I am not able to find a decent editor which allows me to write well-indented Pascal code like I can with C/C++ (I prefer to use terminal editors like Jed or VIM instead of GUIs like Lazarus, but their Pascal mode is not as good as their C/C++ mode). And the last time I checked it, the FPC text-mode IDE was not really usable under Debian/Ubuntu nor under Mac OS X (two of the systems I usually use at work).

(3) The last versions do not provide support for OpenBSD. Maybe switching to the LLVM architecture (I have heard they are investigating this) could help porting FPC to more architectures.

You can say anything you want... doesn't make it true.

And if you actually believe it, then it just proves you really don't 'know about Qt' at all.

Lazarus LCL framework supports GTK1, GTK2, Qt4, Mac OS X Carbon, Windows Mobile and Embedded Linux devices.


Qt is on Win, Mac, X11 (Unix, Linux, BSDs), Embedded Linux, WinCE, S60/Symbian/Maemo, and of course we've just learned here recently about it now being on Haiku, and this article is about it on eCS.

All without the need to change your code, simply recompile your existing code for the target platform. Very cool!


It is cool, but Qt was there & doing that (and on more platforms) long before LCL...

How does LCL beat Qt again?
