[Vala] Is a Direct GCallback to signals possible in vala?
I take a look in the generated C code, and I thought, does signal handling have to be two stages? It possible to do it on 1 stage, right? I'll give an example that shows this behavior: Take a look on gtk_widget_hide_on_delete method in GTK. This method were ment to be used as direct callback to delete-event, for popup hiding popup windows when user click something outside of this window. I thought I'll embrace it in my Vala code, but I run into a little mess- access to this method denied. This is because of vala behavior a.foo (...) instead of ..._foo (a, ...) . I fixed this by adding Gtk.widget_hide_on_delete to my low_binding.vapi file. So this is how it looked: [CCode (cheader_filename = gtk/gtk.h, cname_prefix = gtk_widget_hide_on_delete)] public static bool widget_hide_on_delete (Widget widget); But then I get: error: Argument 1: Cannot convert from`Gtk.widget_hide_on_delete' to `Gtk.Widget.delete_event' I tried to add a parameter named Gdk.Event event to the method above. I get error from CC that too many arguments in this method, which were only logical to me after I looked on the generated code. So far, the only way to use this method is by writing another method or lambda that calls to: Widget.hide_on_delete (widget) Is it possible to do it by a single GCallback? I'm talking only about static methods, because that for the others have the self order problem. ___ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list

Re: [Vala] Vala logo symbol voting
I totally agree with you that war isn't a good symbolism for this, it is one of the reasons I deleted that proposal. The reason why I created it in the first place was the sound of Vala: it reminds of Valkyrie or Valhalla (and if you've read the Silmarillion it reminds of the Valar), and ancient weapons are strongly connected to those topics, so I wanted to try working on that. But since there are better symbolisms (which also look better graphically :D), I deleted that proposal. I don't know if you've taken a look at the pdf, but there are several proposals which communicate exactly what you said: lightness, easiness, flying etc. A flying carpet isn't a bad idea but personally, I like a wing better, because it's less complex and easier to understand. in case you've missed it: symbol proposals pdf downloadhttp://ubuntuone.com/p/1DBL/ kind regards tobias 2011/8/31 Jim Peters j...@uazu.net Sam Liddicott wrote: 2) The symbolism of ancient warfare is hard to understand.

Re: [Vala] Vala completion support for vim
I don't believe the segfault bug is limited to the CompletionEngine destructor. I ran a quick test by commenting out the entire destructor, and it didn't help (remember I also ran into the problem when I tried creating a CodeDom). I did, however, notice that it adds some log messages via Utils.trace; how do I check the log? It looks like it just passes it along to GLib.logv(), but I don't know where this method sends the information.

Re: [Vala] Vala completion support for vim
I believe I've found the problem. =) I figured out how to enable debugging and discovered that the segfault occurred in the CodeDom destructor. Part of the destructor runs a foreach loop on source_files, which was null. In order to make sure that object creation worked correctly, my test included creating a CompletionEngine but adding nothing to it; hence, a null list and the cause of the segfault. It should be easily fixed by making sure that the list always exists, even if it's empty.

Re: [Vala] Vala logo symbol voting
Probably far too late in the process to come back and comment on this but I have a few general comments. I really like the concept of wings etc and think of the logo marks, all but #4 are really very strong, to me #4 is the weakest and is only good. However, I really dislike the font used for VALA. I totally get that by reducing the number of strokes required to form the letters you are trying to evoke simplicity and lightness as shared qualities. For me it actually suggests a different, less accurate set of ideas: Only a few basic tools - 4 unique strokes build the entire word Very direct and angular - fast yes, elegant no. These would seem more to be the qualities of a low level language (assembler or c) rather than a modern, high level language. Vala provides lot's of tools and high level objects to it's users that should let us express ourselves in a much more elegant fashion. Appreciate these comments may be coming at the least helpful time and regardless the outcome will clearly be to a very high standard.
