What's wrong?

Creation methods with parameters are ignored

For example

var box = new gtk.Box(gtk.Orientation.vertical, 4);

var box = new gtk.Box({orientation:gtk.Orientation.vertical});

are not working, the box has no vertical orientation or an error.

But this works:

box.orientation = gtk.Orientation.vertical;

Similar in

label = new gtk.Label("test");

This label has not the given text "test" inside it.

But this works:

label.set_label("test");

or this works,too:

label = new gtk.Label({label:"test"});

Error message when linking library

I get an error message with the few code of var rpg = Gir.load('rpg', '0.3'); Nevertheless I can use my library.

Midgard GIR file is from Ubuntu OBS packages, and today's checkout of node-gir.

notes for building and running examples

eg:

to run the examples, first build the project with

node-waf configure
node-waf build

then run $SCRIPT with node $SCRIPT.

problem connecting signals (gir/gtk3)

i've some problems to understand where i fall, because it seems that when i try to connect a callback to a menuitem, when i click on that, it repeats the launching of the callback a number of times equals to the number of elements in that menu.

probably the function that link callbacks needs some work.

example:

var menu1=new gtk.Menu();
var menu1label=new gtk.MenuItem({label: "File"});
var openlabel=new gtk.MenuItem({label:"Open"});
var quitlabel=new gtk.MenuItem({label:"Quit"});
quitlabel.on("select", function() { console.log("quit"); } );
openlabel.on("select", function() { console.log("open"); });
menubar.append(menu1label);  

menu1label.set_submenu(menu1);
menu1.append(openlabel);
menu1.append(quitlabel);
menu1label.show_all();

GError implementation

GError should extend Exception. Every derived exception should depend on GError's domain. For example, GFileError should be propagated as FileError exception with particular codes.

Arguments in structure constructor

C structures are propagated as objects. However, node gir structure's constructor doesn't accept arguments if C function requires such to create new structure.

explain how to generate documentation from gir file in the README

This link is handy :
https://live.gnome.org/GObjectIntrospection/Doctools

three lines after the WebKit 3.0 documentation is generated :)

Crash in the Guitar Tuner example

I ported the guitar tuner example from GNOME developer docs to node-gir and CoffeeScript:

https://github.com/bergie/node-gir/blob/master/examples/guitartuner.coffee

When I try to make GStreamer to play a sound (by clicking a button), there is a segfault. Backtrace is:

reconsider name mangling on api

saw bergies post in node gir, im the maintainer of seed, so if you need help there is a javascript mailing list on gnome.

Please rethink the camels method mangling, it will break all compatibility between gjs and seed.

The connect<>on mentioned should be feasible in the javascript wrapper layer

Is this dead?

yes I have gtk3 installed. example works fine when using gtk2.

Xvfb support

Hi,
I'm trying to run some of your examples on a headless server / via Xvfb on a Linux box. I figured I'd ask if you had any advice / if this were possible.

The end goal is basically to run a headless server running some the examples in the ./examples dir, and then using a remote machine's browser to connect to the headless server to run the examples.

I'm going through it right now.

Thanks!

missing license and copyright

Hi,
i suppose you just forgot to set them...

Failed to convert argument 2 "3" to GI Type tag "interface"

I understand it is a missing type in node-gir.

This comes up when doing
webView.get_main_frame().print_full(printOp, gtk.PrintOperationAction.export);
or the webkitgtk C equivalent :
webkit_web_frame_print_full(mywebframe, myPrintOperation, GTK_PRINT_OPERATION_ACTION_EXPORT)

Why was the license stripped out?

Just curious, but some portions of this code was licensed under GPL2, and the license was stripped out. I think that’s technically a license breach. Any particular reason the license was removed?

use gtk3

the latest version of gtk is gtk3. node-gir is a brand new project, there's no reason to start it off by using legacy gtk versions.

Where can I find documents about node-gir please?

As I discovered that GNOME's docs are really unfriendly to JS-only developers.
And after a long time I didn't find a document about seed or gjs as friendly as Node APIs.
That's why I want to try node-gir.
Please is there any document I can refer to in writing GTK applications with node-gir?
I mean is there a plain description about gir when you implement node-gir?

Thanks.

New Maintainer

I'm looking for a new maintainer. I don't have time to even review pull requests for this project. Who wants to take over? @swick @daball
