You are welcome. I agree about that is what one expect found in "resizing" functions. I don't have time now, but on monday I will search on GtkContainer.

In Python,gtk.Widget.get_allocation() and gtk.Windget.allocation(as an attribute) return the same gtk.gdk.Rectange,which indeed is the actual size.
So i guess get the size is a solved problem now.
What i need about setting the size of the widget is not about the minimum one.It more like setting the 'allocation' size and not to prevent the widget from resizing to a smaller size by the user manually.
Maybe it's not clear,but i don't know how to explain myself better.

widget->allocation.{width,height}
To set the size (minimum size):
gtk_widget_set_size_request
Example:
static void _label_size_allocate(GtkWidget *a_widget, GtkAllocation *a_alloc, gpointer a_data) { printf("size %d %d\n", a_widget->allocation.width, a_widget->allocation.height); }
int main(int a_argc,char **a_argv) { GtkWidget *l_label; GtkWidget *l_window;
gtk_init(&a_argc,&a_argv);
l_window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
l_label = gtk_label_new("hello"); gtk_widget_set_size_request(GTK_WIDGET(l_label),800,600); // To see de changes with manual resize. g_signal_connect(G_OBJECT(l_label), "size-allocate", G_CALLBACK(_label_size_allocate), NULL);
gtk_container_add(GTK_CONTAINER(l_window),l_label); gtk_widget_show_all(l_window);
gtk_main();
return 0; }
gtk_widget_size_allocate doesn't work for me.

I find gtk.Widget.get_allocation() would work,even when the label is resized.It returns a gtk.gdk.Rectangle(x, y, width, height),like (0, 0, 74, 17).
And,how to set the size of gtk.Label?Is gtk.Widget.size_allocate() the answer?

Output: 31 17
Maybe in python is: gtk.Label.size_request()

There seems no answer in the pygtk API(me using Python currently). gtk.Label.get_size_request() only return (-1,-1).
Google doesn't give much information too. _______________________________________________
