2d image manipualtion in a gtk widget.

Hello, i need to do some 2D image manipulation in a GTK+ widget (well, actually i'm using gtkmm, but it should not matter).. Which is the best 2D canvas to use? I would like to use some acceleration method like OGL Pixmaps. Greeting, Luca ___ gtk-app-

g_main_context_unref

Hello, I would like to unref the default main context after use for proper cleanup. However, this leaves a dangerous invalid pointer in default_main_context. Should this be fixed? I am not quite sure about the locking/atomic issues though. Carsten --- gmain-orig.c2004-11-08 19:49:35.0

static build

Greetings all! I am trying to do a static link of my application using the gtkmm library. Yeah, I know: why Bob? Well, I have installed the gtkmm package using ./configure --enable-static; but the output of `pkg-config --libs gtkmm-2.4` continues to start with the "-Wl,--export_dynamic" option.

GtkTextBuffer: how to insert new line?

Hi, how do I insert a new line after I inserted text into a GtkTextBuffer? I am using gtk 2.4 (with win32/mingw) and got gtk errors when I tried to insert "\n" into the text (this fist approach is probably completely wrong, I suppose ...). I read that there are bugs in gtk -- could not find anyt

Re: GtkTextBuffer: how to insert new line?

I just tried this: gtk_text_buffer_insert_at_cursor(buffer, "\n\n\n\n", 4); and works fine here (gtk 2.4.10). What call are you using? Felix Kater wrote: Hi, how do I insert a new line after I inserted text into a GtkTextBuffer? I am using gtk 2.4 (with win32/mingw) and got gtk errors when I tri

how to make a function thread safe?

Hi, is a function thread save when all inside code is wrapped into a static mutex? What is with this function: Could a second thread influence the first thread while it is looping (because of the pointer argument)? void f(gint* my_gint){ static GStaticMutex my_mutex = G_STATIC_MUTEX_INIT;

Re: Compile line options for a libglade project?

Thanks to the people who have replied so far. Attached is the glade file and the c file. I've check and rechecked the glade and c files for syntax errors, etc. I found one typo that I corrected: I had "int main (int argc, *argv[])" which I changed to "int main (int argc, **argv)". My compile l

You cannot use -1 for the length, at least according to the documentation. voidgtk_text_buffer_insert_at_cursor (GtkTextBuffer *buffer, const gchar *text,

Paolo Costabel: > You cannot use -1 for the length, at least according to the > documentation. [...] > Plus, why are you adding a NULL terminator? Thanks, that's it. I took the -1/NULL terminator thing from the function above in the doc where that is possible (gtk_text_buffer_insert). Felix __

"gtk+" + "omniORB" ( corba )

Is it possible ( and a good idea ) to code a program with GTK+ and omniORB at the project ? I heard issues about this ( something about thread incompatabilities ), but I'm not sure about that. I could do what I want with Bonobo, but I don't want to be "attached" to Gnome libraries ( libGnome a
