Since you use gnomeprint, I understand that you want to print this stuff out. pango_layout_set_width() is what you want to use. Something like this perhaps: (width, margin_left and margin_right comes from gnome_print_config) pango_layout_set_width (pango_layout, (width - margin_left - margin_right) * PANGO_SCALE / 2); Stian Skjelstad ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

pixel is internal value against Xlib. It makes a lot of sense when for

When you are linking the program, do you use `gtk-config --libs` or `gtk-config --libs --cflags` then. Both those two should set options you need to link gtk itself. If you do, you need to manually send a -L/path/to/where/searchforlib to gcc or ld when linking. You can have as many -L options as you would like.

I'm not an expert but: Events that are queue'd are not scheduled until glib iterates again, so they will be "lost" yes. Even signals you emit by hand will be "lost" after the handler is unhooked. Atleast logic should be like that.

Naughty boy :-p setitimer can be very nasty if the signal handler
interacts with gtk code. However, you can do it more nice by doing a
trylock() call and just exit silenty if that fails. Glib has a
timer-callback, but it requires that you are within the gtk_main context
when it times out, else it will linger until it does, and then send the
g_signal.

GDK_THREAD_LEAVE() and GDK_THREAD_ENTER are macroes that tests if
threading is enabled or not before lock/unlock. You can look up those
macroes and check if threading is enabled by poking the functions it uses.

Use two threads. One for perl and one for the rest of the program. Unless

Read the threads section of the api-manual of gtk and gdk, and the usage
of gdk_threads_enter() and gdk_threads_leave(). Sounds very like thread
race problem. For all glib events, you need to call
gdk_threads_enter()/gdk_threads_leave by hand. Events that comes from gtk,
already holds this lock.
gtk main looks like this
while (!quit)
{
gdk_threads_leave(); /* unlock */
let_glib_run_until_we_have_a_event;
gdk_threads_enter(); /* lock*/
handle_events;

You can however copy out the widget from the gtk source tarball and modify it after your own specifications, and make the edited signal return an iter instead. I did this for one my projects (even made it using a different model than the treeview uses). Only one problem, and that is that you can't detect that a user cancels the edit, since it uses a private function (atleast in 2.6.0) to detect this. That should be fixed, if it isn't that already.

The store_model's work indepentently of the views.

Read the thread-section in glib and gtk reference manual, they describe the usage og gdk_threads_enter/gdk_threads_leave. Any thread can update any widget, since a change will enqueue a draw event that will be executed in the gtk_main() thread. A classic example for mvc is to store your data in a gtk_list_store og gtk_tree_store. You can even filter and sort, by stacking models. And Treeview is the presentation.

Where does GTK look for the 'sufficiently new > FreeType'. freetype-configwill reveal the freetype version you are using. But you need pango between. gtk talks with pango, and pango talks to whatever font-system is available at the host. What gtk version are you trying to compile?

To find symbol-definations etc, you can use objdump. objdump -r -R -t -T test.sowill give you all symbols (provided, and needed).

Re: Newbie Question about installing GTK+-2.6

Or to a filesystem that doesn't have filemodes like fat. Or you are not the same user as uncompressed it (but it should not be a problem, since the script has mode 755) Stian ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

You need to have the development packages installed aswell. On debian I recall that they have the same name, byt suffixed by -dev, so if you have binary package "foo" you would install "foo-bar" aswell. Install the development package to X and fontconfig and you can compile pango. But doesn't debian woody already provide binary-packges for pango 1.8.0 etc?

A code example would be really > welcome! thx Increase your buffer to be 4096 bytes atleast even much bigger like a megabyte to lessen the number of iterations you need and number of syscalls done. You will need to loop reading/writing until you aren't able to read any more data. If you are in Gtk it can be a good ide to call g_main_iterate inside the loop, so the program doesn't freeze for the user.

Correct, the configure flags are to determine if you want to make static and/or dynamic/shared libraries. If you add -shared or -dynamic, you make gcc/ld have a preferred choice if it finds both shared and dynamic libraries. -shared is the default.

Hello there
You probably hate threading questions by know, so bare with me.
Are you supposed to use gdk_threads_enter() and gdk_threads_leave from
within a glib callback?
I have this code
static gboolean pollin(GIOChannel *source,
GIOCondition condition,
gpointer data)
{
gdk_threads_enter();
do some stuff to a GtkListStore to append some info the source gave me
gdk_threads_leave(); <- here it hangs
return TRUE;
}
I'm now recompiling glibc, glib and gtk in order to get symbols in gdb,
back-traces.
