Re: Displaying domain objects with GtkTreeView
2011/12/1 David Nečas y...@physics.muni.cz: What are you talking about? You can pass any GObject-derived type as the column type (not that it matters much, the net result is the same as passing G_TYPE_OBJECT). You get back the objects that you stored there. If you store objects of different classes to the same column and want to know the precise type use RTTI: type macros such as MY_IS_FOO(), G_TYPE_FROM_INSTANCE(), g_type_is_a(), etc. Hi I rather meant to use my object as a model for a whole, multi-column row, somehow binding fields or properties to columns.

It makes no sense (to me anyway) to imagine one object as multiple *model* columns. But it is easy to create an arbitrary M:N mapping between model rows and view rows using the cell data functions, see gtk_cell_layout_set_cell_data_func() which is probably the binding you are looking for.

Might be that what you look for, Rafal, is model.set_modify_func () - it allows him to synthesize model columns on the fly, from e.g. objects in the real model column. The modify func then can look st. like this: def modify_func (model, iter, col_num, attrs): obj = model.get_value (iter, 0) col = attrs[col_num] try: return getattr (obj, col) except: return '' For some performance penalty.

Re: Can I develop gtk app in Mac OS X ?
Here is a starting point to install GTK on OSX: http://live.gnome.org/GTK%2B/OSX/ And It can running separately from X in OSX? YES, the build documentation I pointed to is for the native (Quartz) version of GTK, that works quite well (still has some minor bugs here and there). You can also bundle GTK libraries inside an OSX .app with the gtk-mac-bundler. The X11 version of GTK can be easily installed from fink or macports, but it needs an X11 server running on your machine and it's not friendly at all if you want to create an application you want to share with someone. -- Bye, Gabry ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Embedding OpenGL into GTK apps

Is it possible? And if so, how? This is a necessary component for my thesis at university. GtkGlExt (surprisingly - quite out of support) does not seem to work. I even tried to link against it with gtk 2.0, but it doesn't work either. Nasty things like this are written to stdout: (process:9338): Gdk-CRITICAL **: IA__gdk_x11_display_get_xdisplay: assertion `GDK_IS_DISPLAY (display)' failed (process:9338): GdkGLExt-WARNING **: Window system doesn't support OpenGL. I am using Arch linux with GNOME 3, [base], [community] and [extra] repos enabled only, latest nvidia graphics card with proprietary drivers. I am using gtkmm in C++11, but I couldn't achieve anything even in plain gtk, and if a solution exists in gtk, I think it would be portable to gtkmm. Thanks, Dennis P.S.: An equally good solution would be to draw gtk inside an opengl canvas, that way my whole application would be drawn in opengl. Is that possible? I asked this question a while ago at stackoverflow (at that time I were not aware of this mailinglist): http://stackoverflow.com/questions/3815806/gtk-and-opengl-bindings Regards Bernhard Hi, Thank you, I will give GtkGlArea a try as soon as I have some time. Unfortunately Cairo is not an option for me as I have to be really fast. I'll report back later!

Re: Can I develop gtk app in Mac OS X ?
Here is a starting point to install GTK on OSX: http://live.gnome.org/GTK%2B/OSX/ And It can running separately from X in OSX? Not yet. Actually you can run it separately from X server, like an ordinary application, when using Quartz backend. What you need is is to check GTK-OSX project, see more info here: http://www.gtk.org/download/macos.php Basically, you need to build GTK with jhbuild scripts and bundle the GTK libraries with your program.
