  Hi,

  Didn't before but may be check the following:

  g_object_set(G_OBJECT(layout),
app-paintable\0, TRUE, 
NULL);

 Hmm, I hadn't noticed that property. It is presumably set ok since I can
 draw and place widgets on the GtkLayout. It was the configure and scroll
 events that I didn't receive.
 BTW why do you have two NULL bytes at the end of the property name
 (AFAIK only one is needed)?

Assumed you get annoyed by warnings, you can slightly disable it. It's
distribution depend what flags are per default on. For further reading:

You should ask why I forget to add GDK_SCROLL_MASK

gtk_widget_set_events (GTK_WIDGET (layout),
  GDK_EXPOSURE_MASK 
  | GDK_LEAVE_NOTIFY_MASK 
  | GDK_BUTTON_PRESS_MASK 
  | GDK_BUTTON_RELEASE_MASK 
  | GDK_POINTER_MOTION_MASK 
  | GDK_POINTER_MOTION_HINT_MASK 
  | GDK_SCROLL_MASK
  );

then you have to

g_signal_connect(G_OBJECT(layout), scroll-event\0,
  G_CALLBACK(layout_callback), NULL);


gboolean
layout_callback(GtkWidget *widget, GdkEvent *event, gpointer user_data)
{
  /* do your thing */

  return(FALSE);
}

Do you have an other thread?
May be concurrency problems?

 I'm writing an app, that among a lot of other stuff, has three mutually

 C, etc., resulting in a bottomless recursion.  So, what I need to do is, 
 while I'm in A's callback, block the B and C callbacks; while in in B, 
 block A and C and so on.
 
 Every combination of g_signal_handler_block(), 
 g_signal_handlers_block_matched(), etc, I've tried just results in seg 
 faults--all that stuff works fine outside the callbacks, but the moment 
 I stick them in a callback, death happens.
 
 Any suggestions?
 
 Thanks.

 You should ask why I forget to add GDK_SCROLL_MASK

Well, I didn't ask because I already tried it. The GtkLayout didn't
receive that nor the configure signal even with setting
GDK_ALL_EVENTS_MASK. What *did* work is receiving the events on the
parent.
But I am still curious why you have two NULL bytes termination your
signal name strings, the extra one must surely get ignored...

debugging broadway

2014-03-10 Thread Stefan Sauer

hi,

I wanted to see the broadway backend in action. Using gtk+3.8 I run
broadwayd --address=ipaddr --port=8080 :5
and
BROADWAY_DISPLAY=:5 GDK_BACKEND=broadway ./my-gtk3-app

On the browser side, all I get is a blank window with a title containing
broadway 2.0. Tested with chrome 33.0 and firefox 27.0.

Firefox has this in the firebug console:
NetworkError: 404 File not found - http://xxx:8084/socket-test;
socket-test
Firefox can't establish a connection to the server at
ws://xxx:8084/socket-test.
ws = new WebSocket(loc, broadway);
broadway.js (line 2625)
NetworkError: 400 Bad websocket request - http://xxx:8084/socket-bin;
socket-bin
Firefox can't establish a connection to the server at
ws://xxx:8084/socket-bin.
ws = new WebSocket(loc, broadway);

Chrome shows:
WebSocket connection to 'ws://xxx:8084/socket-test' failed: Error during
WebSocket handshake: Unexpected response code: 404 broadway.js:2625
WebSocket connection to 'ws://xxx:8084/socket-bin' failed: Error during
WebSocket handshake: Unexpected response code: 400 broadway.js:2625
'KeyboardEvent.keyLocation'' is deprecated. Please use
'KeyboardEvent.location' instead.
event.returnValue is deprecated. Please use the standard
event.preventDefault() instead.

According to http://websocketstest.com/ both browsers have full
websocket support.
 
Any ideas?

Yes :/ I'ved played a bit with the js debugger in the browers but still
not success.
Is there any order for launching stuff? Like
1) broadwayd, 2) connect from browser, 3) launch gtk-app?

Also, there is a keyboard handler handleCommands() on the js side. But
pressing keys in the browser window seem to not show any effect. When I
set a breakpoint on handleCommands() its not called, which makes me
thing that the handler is not active.
