Gtk-3.14.3 on Windows: icon rendering issues

[Daniel Kasak <d j kasak dk gmail com>]

Hi all.

I've just paid a developer to build a distribution of Perl & Gtk3 & bindings for Windows ( I tried building it myself, but there were just too many issues ). It's working great, with only 2 apparent issues:

1) Some icons are missing. I use the following code to generate icons for buttons:

Gtk3::Image->new_from_icon_name( $this_item->{icon_name}, "button" );

In C I guess this translates to:

gtk_image_new_from_icon_name (const gchar *icon_name,
                              GtkIconSize size);

Why are some icons not being rendered? Is this a packaging issue? I see the same issue in the gtk demo apps. Also note that there is an image in the combo box that's also not being rendered. I'm hoping this is just a case of chucking a png file or 2 in the correct place now :)

2) More disturbingly, I'm getting some errors in Windows that I don't see in Linux:

*** unhandled exception in callback:
***   Can't locate object method "new_from_file_at_size" via package "Gtk3::Gdk::Pixbuf" at window/browser.pm line 84.
***  ignoring at C:/strawberry/perl/site/lib/Gtk3.pm line 318.

The code in question here is again rendering some icons:

    # render icons
    $self->{icons}->{CONNECTION} = Gtk3::Gdk::Pixbuf->new_from_file_at_size( $icon_folder . "/connection.png", 24, 24 );
    $self->{icons}->{DATABASE} = Gtk3::Gdk::Pixbuf->new_from_file_at_size( $icon_folder . "/database.png", 24, 24 );
    $self->{icons}->{TABLE} = Gtk3::Gdk::Pixbuf->new_from_file_at_size( $icon_folder . "/table.png", 24, 24 );

What's going on here? Surely this method of rendering icons hasn't been removed? Admittedly, I'm running Gtk-3.12.x on Linux, and 3.14.x on Windows, so maybe things have changed underneath me?

When I get on top of these issues, I'll be hosting packages and detailed build instructions that will be useful for Gtk-Perl people like me, and I assume also Python & PHP people. Apparently it was "damn nigh impossible" to build GObject Introspection and some other packages on Windows. Anyway if I could get a little insight into these icon rendering issues, it would be greatly appreciated :)
