Hi Christian,

Thanks for the reply.  The exact problem I am facing is the destruction of the Socket & Plug widgets.
Currently what I am doing is:
- While creating the plugin, I am creating the plug using gtk_plug_new(). I am adding my plugin windows & controls to the plug.
- At the time of deletion of plugin, I am freeing all the resources allocated during the usage of plugin.
- At this time, I am calling for gtk_widget_destroy(plug).
- The problem is at this point. After the last step, the plug is destroyed, but what about the socket created for holding this plug? I am catching the "plug-removed" signal, but that callback is never getting called.

As a result, according to me, the socket created is getting accumulated. So, if I open 5 plugins, I am accumulating (leaking) 5 socket widgets. So, I wanted to know, whether there is any special way of deleting the plug, so that "plug-removed" signal is automatically invoked. Also, how do we destroy socket by calling gtk_widget_destroy(socket) call?

I was going through gtk+ code and I found there are functions "_gtk_plug_remove_from_socket()" & "gtk_plug_get_socket_window()". Can I use these functions as I didnt found these functions reference anywhere in Gtk documentation? If I can, should I use these functions to complete the destruction process? Please let me the exact protocol.

Thanks in advance,
Ravi Phaneendra K

Hi all,

I am creating a plugin for a browser based on webkit, using the xembed
protocol i.e. using GtkSocket & GtkPlug. I have been successfully able to
create the plugin & show the content required on the plugin window, but I am
facing problem when I try to delete the plugin. At the time of deletion of
plugin, I want to delete the plug created, so as to free the resources
allocated to the plug while creating plugin. Can anyone tell me how to do
it, including how to do the cleanup on the GtkSocket side created in the
browser?

It would be of great help if anyone could let me know on this ASAP, as I am
in urgent need of this information. I tried to find any resource telling
more on XEmbed protocol usage and the cleanup process when using XEmbed
protocol on the web, but couldn't get anything concrete help on this topic.

Thanks & Regards,
Ravi Phaneendra K

Hey Ravi,

so what problem are you facing exactly? From what I understand you have
an nsplugin that creates a socket and loads a plug from somewhere.
Please correct me if I misunderstand the scenario. And I assume you are
in charge of the socket and plug code. So both are GtkWidgets which
have the usual finalize, dispose and destroy, plus the "plug-removed"
signal on GtkSocket.

I haven't used this in a while since it is somewhat messy, so it would
be good if you could provide more context about what you are doing and
what is not working.

Yours,
   Christian
