Re: saving window size?
Look at GtkWidget::delete_event signal.

Hi all,
Suppose I have an app, and I would like to save the window size when
when quitting.
This is easy to do if the user selects File-Quit, but what if they
click window-close? By the time you get the destroy signal, the true
width/height values are gone. (You seem to get the default values.)
Is there a resize signal I can listen to?
Here's what I have, in vala:
window.destroy += quitSave;
//quit menu item
Action quit = (Action)builder.get_object(menubar_quit);
quit.activate += (quit) = {quitSave (window);};
...
private void quitSave(Window window)
{
var gc = GConf.Client.get_default ();
int width = 0;
int height = 0;
window.get_size (out width, out height);
if (width 0)
gc.set_int (/apps/moserial/ui/window_width, width);
if (height 0)
gc.set_int (/apps/moserial/ui/window_height, height);
Gtk.main_quit ();
}
Suggestions?

Re: How can I wrap or scroll text inside a GtkLabel to keep the width?
Guenther Meyer wrote: hi, I have GtkLabels packed inside some vboxes or tables, the width of the box is determined by the size of some other elements (buttons, listviews, ...). when the text inside the labels is changed, and this text is too long to fit, the box automatically resizes, which distorts the whole window layout and pushes some widgets off the screen. so how can I fix the width of the GtkLabel (which I don't know at creation), and let the text automatically wrap or scroll, if it doesn't fit? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list Hi. voidgtk_label_set_ellipsize (GtkLabel *label, PangoEllipsizeMode mode); Sets the mode used to ellipsize (add an ellipsis: ...) to the text if there is not enough space to render the entire string.

From giochannel.c:
guint
g_io_add_watch_full (
GIOChannel *channel,
gint priority,
GIOCondition condition,
GIOFunc func,
gpointer user_data,
GDestroyNotify notify)
{
GSource *source;
guint id;
g_return_val_if_fail (channel != NULL, 0);
source = g_io_create_watch (channel, condition);
if (priority != G_PRIORITY_DEFAULT)
g_source_set_priority (source, priority);
g_source_set_callback (source, (GSourceFunc)func, user_data, notify);
id = g_source_attach (source, NULL);
g_source_unref (source);
return id;
}
g_source_attach docs say:
Adds a GSource cid:part1.08000109.07070102@gmail.com to a /|context|/
so that it will be executed within that context.
/|source|/ :
a GSource cid:part1.08000109.07070102@gmail.com
/|context|/ :
a GMainContext cid:part3.06080301.01060802@gmail.com (if |NULL|
cid:part4.06010104.01000906@gmail.com, the default context will be used)
/Returns/ :
the ID (greater than 0) for the source within the GMainContext
cid:part3.06080301.01060802@gmail.com.
From gmain.c (g_source_attach func):
if (!context)
context = g_main_context_default ();
So, main loop is found throw GMainContext.

Re: Callback Question
Hi. Perhaps, this discussion was related to threads? Thank you all for this! Especialy for the long example, but, it was just an example. I've made an application that works perfectly on Linux but in Window$ it crashes a lot! I've been trying to find a solution (actually a clue of what the problem might be) in any discussion I was able to find about GTK crashes in the internet. In one of these discussions it was said that gtk functions can't be called inside callbacks, that it wasn't safe yet. That, if you call any gtk function inside a callback, it should be done using g_object_idle_add. Unfortunatly I didn't check the date of the discussion, maybe, it is too old. Thanks.

Re: Draw text to a GdkPixbuf
Why don't you want to draw the text you need in your expose function? You simply redefine the GtkWidgetClass expose-event and draw there.
