glib network connection example

阅读更多关于 glib network connection example

问题 Can you advice some network connection example made with glib/gio libraries. There is quite a good reference manual, but no full example even for basic things. It will be used for simple sending and receiving files as a part of program. 回答1: How about like this? There is similar question at Fetch a file from web: in GTK using C #include <gio/gio.h> int main() { const gchar *uri = "https://stackoverflow.com/questions/5758770/"; GFile *in; GFile *out; GError *error = NULL; gboolean ret; g_type

Within Python, what is exactly a sequence of strings? (or else Glib bug?)

阅读更多关于 Within Python, what is exactly a sequence of strings? (or else Glib bug?)

问题 I know the question may looks stupid, but I am really not able to figure it out. I naively though a sequence of strings is a list of strings. However, this fails: (pid, stdin, stdout, stderr) = glib.spawn_async( argv=["foo", "bar"], envp=None, flags=glib.SPAWN_SEARCH_PATH + glib.SPAWN_CHILD_INHERITS_STDIN, standard_input=True, standard_output=True, standard_error=True) Fails with this error: TypeError: glib.spawn_async: first argument must be a sequence of strings I tried with a tuple, which

Is glib usable in an unobtrusive way?

阅读更多关于 Is glib usable in an unobtrusive way?

问题 I was looking for a good general-purpose library for C on top of the standard C library, and have seen several suggestions to use glib. How 'obtrusive' is it in your code? To explain what I mean by obtrusiveness, the first thing I noticed in the reference manual is the basic types section, thinking to myself, "what, am I going to start using gint , gchar , and gprefixing geverything gin gmy gcode gnow?" More generally, can you use it only locally without other functions or files in your code

Possible to run multiple main loops?

阅读更多关于 Possible to run multiple main loops?

问题 I'm working with both libfuse and the glib event interface and I've run into an issue where I need to run multiple main loops concurrently (glib's g_main_loop_run and fuse_loop_mt ). I've already attempted to created a detached thread for glib's event loop under a secondary context, e.g.: static void * event_loop(void *arg) { GMainLoop *event_loop; GMainContext *context; context = g_main_context_new(); g_main_context_push_thread_default(context); event_loop = g_main_loop_new(context, FALSE);

Is it possible to define GTK+ type using gtkmm?

阅读更多关于 Is it possible to define GTK+ type using gtkmm?

I would like to define a new subclass of some gtkmm type, implementing interface of underlying GTK+ object. Then, i want to compile it into some kind of dll and use in pure C code (GTK+, no gtkmm) through this interface. Is it possible? The followings are required to use gtkmm widget in GTK+ : implement the desired custom widget in gtkmm create a library from the widget for Glade design the user interface containing the custom widget with Glade declare the C interface for the application written in GTK+ build the user interface from XML with GtkBuilder Details can be found in my blog post . 来源

How do I register a profile with bluez using dbus/gio?

阅读更多关于 How do I register a profile with bluez using dbus/gio?

问题 I'm trying to register a profile with bluez through D-Bus/Gio. When I call RegisterProfile everything goes OK. I check my GError and it's NULL and my return value is an empty GVariant. I've tried many things, but here is my latest code. When I run it, it prints "g_dbus_connection_call_sync succeeded", but I can't see my new profile in D-Bus using d-feet and I cannot connect to it using a my test device. I know the code on the test device works, or at least did work with straight bluez, but I

问题 I am attempting to use pynotify for a small project, but am having a strange problem on my Fedora 13 machine. It appears that when pynotify is run programmatically it crashes when show() is called - however if I type that line myself it runs fine! I have tested it also on my Ubuntu box, where it runs absolutely fine. My testing code is: import pynotify pynotify.init('someName') n = pynotify.Notification("Summary", "Body") n.show() And the results of running this: $ python -i test.py Traceback
