hello

i have saw that all the nice software that has linux version almost all r in gtk2 or gtk base

like
---------
mozilla
firefox
gimp
gaim
xmms
gmplayer
inkscape

other like

ymessenger (they use gtk may be for avoid the close source license in qt)

now a days the gaim and other is type of software is porting to kde like gaim = kopatte etc etc


( i like both kde and gnome (also others) both r seems perfect to me i use both)

my questions it why the gtk is the frist choise of this type of cool software developers
is gtk and gtk2 mean the default linux gui!!!

thanx

well generally it would be a toss up between gtk (gnome) and qt (kde). While i've programmed in gtk for every UI i've ever made, i've very litle Qt experience, so i'm not too suitable to comment really. AFAIK gtk has a significantly smaller footprint, requiring less of Gnome to be present to do funky stuff, than QT requires of KDE, therefore it's somewhat more portable.

Another big point is the licensing. QT isn't acutally availbae under the GPL, and is developed by Trollech primarily as a profit making application. this limits many aspects of it, especially when you are coming from a bigger developer, such as mozilla.org where licensing can be a little prohibitive.

So while KDE does have a bigger user base than Gnome, their toolkits have the opposite impact.

Bascially it suits active aplication development more.

and looks better.

I've done a little programming in both gtk (and gtkmm, gtk-perl) and Qt and have to say that Qt is simply horrible to program in because of the awful Meta Object Compiler. Every class that inherits from the Qt base class needs to be pre-compiled on the MOC. It just looks like a hideous botch job to get signals and slots working before C++ was really ready for them, unlike gtkmm which works in a much more natural C++ style.

And as the guy above said, it also looks better
