Help with gtk+ binding for perl6

hdias has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

I'm doing a perl6 script that uses the NativeCall module to map GTK+ library functions.

The script can be seen below:

#!/bin/env perl6 use NativeCall; constant LIBGTK = 'libgtk-3.so'; constant GTK_WINDOW_TOPLEVEL = 0; sub gtk_init(int, Str) returns OpaquePointer is native(LIBGTK) is export { ... }; sub gtk_window_new(int) returns OpaquePointer is native(LIBGTK) is export { ... }; sub gtk_window_set_title(OpaquePointer, Str) is native(LIBGTK) is export { ... }; sub gtk_container_set_border_width(OpaquePointer, int) is native(LIBGTK) is export { ... }; sub gtk_widget_show(OpaquePointer) is native(LIBGTK) is export { ... }; sub gtk_main() is native(LIBGTK) is export { ... }; gtk_init(0, ""); my $window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_title($window, "Test"); gtk_container_set_border_width($window, 200); gtk_widget_show($window); gtk_main(); exit();

The script work and open a new window.

I'm trying to follow this example: http://developer.gnome.org/gnome-devel-demos/stable/image-viewer.c.html

Anyone know how to deal with the connect signals?

/* Exit when the window is closed */ g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL) +;

Thanks

[Corion]: Discipulus: If you want to rewrite the SVG, then yes, something like XML::Twig should be enough. I would try to not modify the SVG but only modify the display, but so far I haven't convinced IE to change the style...
Corion gives up
[Discipulus]: ah! so you mean if i need a static image i can use Twig, if on the fly better css selector and mody attrs (jquery?), rigth?
[LanX]: not sure what you guys are taking about, but a DOM manipulation in JS shouldn't be difficult
[Corion]: Discipulus: Yeah, that's what I would try (but so far, I can't even change the colors manually in the SVG, which is why I gave up ;) )
Discipulus bad sign..
[Discipulus]: italian doc says to modify somehow the initial SVG before using it with D3.js
[Discipulus]: LanX the fact is that my js ability is even poorer than my Perl one..
[LanX]: oh its negative? ;P
