don't understand file_get_contents

[Jean-Baptiste Bourgoin <monsieur camille gmail com>]

Hello,

I'm playing with Seed and Gi : i tried to write a little text editor.

I don't understand why i can't open a file.

There is the code :

------------------------------------------------

#!/usr/bin/seed

GLib = imports.gi.GLib;
Gtk = imports.gi.Gtk;
GtkSource = imports.gi.GtkSource;
GtkBuilder = imports.gtkbuilder;


function load_file(filename) {

    var file = GLib.file_get_contents(filename);

    this.GtkSource.buffer.begin_not_undoable_action();
    this.GtkSource.buffer.set_text(file);
    this.GtkSource.buffer.end_not_undoable_action();
}

// handlers of file menu

var handlers_menufile = {
    // NEW FILE
    on_mfilenew_activate: function(menuitem){
    },
    // OPEN FILE
    on_mfileopen_activate: function(menuitem){
        var dialog_open = new Gtk.FileChooserDialog({
            title: "Open File",
            action: Gtk.FileChooserAction.OPEN
        });
        dialog_open.add_button(Gtk.STOCK_CANCEL,
Gtk.ResponseType.CANCEL);
        dialog_open.add_button(Gtk.STOCK_OPEN, Gtk.ResponseType.OK);
        dialog_open.run();
        if (dialog_open.run() == Gtk.ResponseType.OK) {
            var filename = dialog_open.get_filenames();
            load_file(filename);
        }
        dialog_open.destroy();
    },
    // SAVE FILE
    on_mfilesave_activate: function(menuitem){
    },
    // SAVE AS FILE
    on_mfilesaveas_activate: function(menuitem){
    },
    // QUIT
    on_mfilequit_activate: function(menuitem){
        Seed.quit();
    }
};

// display

Gtk.init(Seed.argv);

b = new Gtk.Builder();
b.add_from_file("graineed-main.glade");

b.connect_signals(handlers_menufile);

d = b.get_object("window1");

// d.Widget.set_size_request(400, 600);
d.show_all();
d.set_title("Graineed");

Gtk.main();

------------------------------------------------

The error :

** (seed:13225): WARNING **: Exception in closure (0xa082148) for signal
handler (GtkBuilder) (handler [anonymous]). Line 10 in file_action.js:
GInvokeError Too few "out" arguments (handling out)

The line 10 (in the original source code) is "var file =
GLib.file_get_contents(filename);"


You can get the source code here :
https://github.com/jbbourgoin/Graineed

Load_file work, when I write a "print(filename);" before
file_get_contents I have the file with his path. I don't understand the
signification of the bug report.

If you have an idea, and I think you have, this is a simple problem
after all ;) (except for a beginner !).

Thanks,

JBB

P.S. : You can identify faults in my prose, I'm not very good in
english, but I want to improve it ;)
