Re: gtk application getting stuck in g_mutex_unlock

[Lokesh Chakka <lvenkatakumarchakka gmail com>]

emmanuele,

thanks for your quick response.

As per your suggestion, I added gdk threads init/enter/leave. Still I am facing the same problem.

Regarding the context,

I am working on a proprietary software which analyses network traffic and plots that info as a graph. you can visualize this as similar to system monitor.

This software takes configuration from end user. For configuring, we are using spin buttons, combo boxes, buttons, tool bar, pan, notebook, file chooser, scrolled windows etc.

For plotting the graph, I am using color buttons, cairo graphics etc.

please let me know if I have to give any more related to context.

Thanks & Regards

I bet that started happening because you updated GLib but not GTK+…

No, it's very likely an issue in your application. Let me guess:
you're initializing threading support, but you're not acquiring the
lock before calling gtk_main().

You probably want to read this:

If acquiring the GDK lock does not fix the issue, you'll have to
provide more context.

Ciao,
