Just checked the source for 2.4.13 and 2.5.5. Both use a GtkToggleButton...
Check the following "scan" function - should print a list of found object types:
static void scan_children( GtkWidget *w, gpointer data ) { g_print( "%s\n", G_OBJECT_TYPE_NAME( w ) ); }
For me it finds:
GtkToggleButton GtkEntry
Unfortunately I only get GtkEntry :-(
I've checked that the first argument to gtk_container_forall() is a GtkComboBoxEntry
And according to printout from the callback it has only one child which in an GtkEntry.
According to the documentation on my machine it should be 2.4.13 I have on my FC3 - this is really strange!
The test you ran was that on a 2.4.13 or 2.5.5 or both?
About GTK_IS_... macro:
There are six std macros defined by every Gtk+ "class". They are used for: 2* type checks (GTK_IS_...[_CLASS]) 2* obj casts (GTK_...[_CLASS]), e.g. GTK_BIN( my_combo )->child 1* the type system internal type (GTK_TYPE_...) 1* get the objs class (GTK_..._GET_CLASS)
Thanks for the explanation.
E.g. if you look into the code, you will find a lot of
g_return_if_fail( GTK_IS_...( combo ) );
For more information read the Gtk+ tutorial and http://www.le-hacker.org/papers/gobject/
I think these six macros should also be in the reference manual.
I expect to be able to find any (public) available function/macro in the reference manual.
And be sure you use gtk_container_forall not gtk_container_foreach!
I checked in the reference manual before use - and know the difference! But thanks for pointing it out.
