Qt has also its own object model (QObject) that extends the C++ standard model with runtime introspection, signals, etc ... Qt uses a modified C++ syntax. GTK+ is pure C. Typical C apps require more boilerplate code, but simple code generators can do the bulk of work for you. > - Qt can rely on QtDesigner and KDevelop that, together, make up a real IDE > (similar to Visual Studio) > - GTK must rely on Glade only, that is a GUI builder equivalent to QtDesigner. > There is nothing like KDevelop for GTK (AFAIK). Anjuta is actually *IMHO* superior to kdevelop. Only good integration with glade-2 is missing. But you use libglade and xml files anyway though.

The perl bindings for gtk+ are complete. But python bindings cover almost any other gnome lib like the canvas, bonobo, gconf etc ... C++ bindings are cool too though :-) > - Qt has exhaustive documentation and a lot of examples form Trolltech and the > KDE team > - GTK has exhaustive documentation and a lot of examples from GTK team > - Qt is freeware on Linux only > - GTK is always freeware (but it is not completely available on Windows and > MacOS X) Is completely available under windows. As is libglade/glade. Other gnome specific libraries usually arent available under windows. > Should you need to develop x-platform applications, have a look at wxWindows > (and wxPython) as well.

PyGTK2 + GTK2 (e.g. dropline distro) works fine too. But ... QT is a good canvas widget. GTK doesn't :-) (is available in libgnomecanvas though, but doesn't compile on window out of the box, if you are able to compile it all onder windows) > CU > > ---------------------------------- > Alessandro Bottoni > alessandrobottoni@xxxxxxxxxxxx > _______________________________________________ > > gtk-list@xxxxxxxxx > http://mail.gnome.org/mailman/listinfo/gtk-list > > _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
