google trend about qt gtk
http://www.google.com/trends?q=qt,gtk

Thanks for the info.

As I've pointed some days ago, IMHO, GTK is faster, lighter and easier than QT.

So, for those wanting to run HMG apps in other platforms I recommend strongly xhGTK (http://sourceforge.net/projects/xhgtk/).

Porting HMG apps. to it could be extremely easy.

Of course, my opinion is based on my own tests only and I could be wrong...

IMHO to make a decision about a product, the best way to go is to do it, based on your own tests. I always encourage people to do that.

IMHO, making technical decisions based on the thinking of others (ie: a web trend) is a serious mistake.

I've tested myself HBQT and xhGTK (among other multi-platform GUIs) and my opinion is based on those tests.

Anyway, if any is interested on 'popularity', the main flavor of most popular Linux distribution in the world (Ubuntu) is based on GNOME.

GNOME was built using GTK.

Just my opinion...

Another very important thing to consider at decision time is the following:

GTK is is developed by 'GNOME Foundation' :http://en.wikipedia.org/wiki/GNOME_Foundation

QT is produced by Nokia's Qt Development Frameworks division: http://en.wikipedia.org/wiki/Qt_Development_Frameworks
