Why are no developers completing/maintaining native Gtk+ for OS X?
Hello All I'm currently in charge of the development of a cross-platform OpenGL app which uses GTk+ for it's interface. The app runs on both *nix/X.org and win32 but when I started looking into OS X I found that the Quartz OS X version of Gtk+ is neither complete nor being actively developed. I must say I find this rather baffling. I would have thought a platform like OS X to be a priority? I know that solutions like MacPorts provide Gtk+ for the X server in OS X, but I strongly doubt that the average OS X user would know where to begin with a project like MacPorts, and to be honest the look 'N feel * compared to native OS X. Also if a native Gtk+ OS X framework were available people who are maintaining Gtk+ apps would have the option to extend their user base to OS X quite quickly. I would urge anyone with the time and knowledge to consider helping complete Gtk+ for native OS X.

GtkGLExt OS X Quartz hack patch
I've made a patch that allows gtkglext to run on quartz osx without filling up the entire toplevel window. The problem was it seems that a function was used, gdk_quartz_window_get_nsview(widget-window); that allways returns the toplevel window. What I've done is to create a NSOpenGLView and add it as a subview to the toplevel NSView, and then manually resize the OpenGLView when necessary. (In a very hackish way...) I haven't changed anything regarding pixmaps or even the release context functions, but the basic widget/view works... (Full patched source) http://juvul.com/stuff/gtkglext-1.2.0.osx-hack.tar.gz (The previous quartz patch. gtkglext-1.2.0_quartz_patch.diff.7z.001, gtkglext-1.2.0_quartz_patch.diff.7z.001 Apply first!!! ) http://sourceforge.net/tracker/index.php?func=detailaid=2750584group_id=54333atid=473436 (The quartz hack patch) http://juvul.com/stuff/gtkglext-1.2.0.osx-hack.patch To build, just run the commands below in the patched gtkglext folder: (change the dir's to your own first..) jhbuild shell ./configure --with-gdktarget=quartz --libdir=gtk/inst/lib --bindir=gtk/inst/bin --includedir=gtk/inst/include make make install And it should be done.

If you want to do ACTUAL 3D rendering your choises are OpenGL and OpenGL, Clutter doesn't come anywhere near it. It's true that the API is getting better in 3.0+ but you can still do the same with 2.0+. Also it's a matter of personal taste. At the dawn of time John Carmack chose OpenGL and urged all GPU vendors to make OpenGL drivers because of the horrible DirectX API. Of course DirectX has come a long way since, but if you want any form of cross-platform support your only choice is still OpenGL. Integrating raw GL inside a gtk+ application is a niche requirement enough that I'm not at all sure it should be moved to gtk+ itself. And if you're dropping into raw GL there is no way you are not a niche use case. It may be niche as in not many apps use it, but that hardly makes it any less important. When companies like Autodesk ports ther many many $$$ apps to Linux they don't have the choice of using GTK+ As far as I can tell GTK+ is the only widget API on any PC platform that doesn't have an OpenGL widget/view. Not being able to use advanced 3D visualizations in modern day apps seems rather odd IMNSHO.
