UIManager errors
I'm trying to create a simple menu for my app with the new UIManager
functions under GTK+ 2.6. I've copied most of my code for it from
the the gtk-demo.exe app and I still can't get it to work. Compiles fine,
but I get a long list of errors, all of which are like these (same error for
similar code fragments):
Gtk-WARNING **: FileMenu: missing action
Gtk-CRITICAL **: gtk_container_foreach: assertion
'GTK_IS_CONTAINER(container)' failed
Gtk-CRITICAL **: gtk_menu_shell_insert: assertion
'GTK_IS_MENU_SHELL(menu_shell)' failed
Gtk-CRITICAL **: find_menu_position: assertion
'GTK_IS_MENU_SHELL(menushell)' failed
Glib-GObject-WARNING **: invalid (NULL) pointer instance
Glib-GObject-CRITICAL **: g_signal_connect_data: assertion
'G_TYPE_CHECK_INSTANCE(instance)' failed
I've been over the example and the API docs and I can't work out why this is
happening. My code is below. If anyone can help I'd be very appreciative.

GtkList question
I have set the following code to form a list of text items called SPN:
enum { SPN_COLUMN, N_COLUMNS }
GtkListStore *listModel = gtk_list_store_new(N_COLUMNS, G_TYPE_STRING);
GtkTreeIter *iter;
gtk_list_store_append(listModel, &iter, NULL);
gtk_list_store_set(listModel, &iter, SPN_COLUMN, "1st SPN", -1);
gtk_list_store_set(listModel, &iter, SPN_COLUMN, "2nd SPN", -1);
gtk_list_store_set(listModel, &iter, SPN_COLUMN, "3rd SPN", -1);
GtkWidget *list = gtk_tree_view_new_with_model(GTK_TREE_MODEL(listModel));
GtkCellRendererText *renderer = gtk_cell_renderer_text_new();
GtkTreeViewColumn *column = gtk_tree_view_column_new_with_attributes("SPN",
renderer, "text", SPN_COLUMN, NULL);
gtk_tree_view_append_column(GTK_TREE_VIEW(list), column);
gtk_box_pack_start(GTK_BOX(vbox), list, FALSE, FALSE, 0);
which is from 2.0 API for Tree Widgets. Eric Harlow's book gives an example
that uses
gtk_widget_set_usize(list, 250, 250) which is now deprecated. What to I use
to set a minumum size for the displayed list since I
am going to be starting out with an empty list box and would like to set
some sort of minimum size to this widget even though it
is empty.

Re: simple question: are const gchar* arguments hold as copies internally?
Felix Kater wrote: Hi, these two functions take const gchar pointers: void gtk_label_set_text([...] const gchar *str); void g_key_file_set_value([...] const gchar *group_name, [...]) Does that mean that the arguments are *not* hold as copies internally so that I have to care for the allocated memory -- or can I savely pass a temporary character string as an argument to the functions which make a copy of the strings internally and also release their memory when necessary automatically? Generally, if a function takes `const gchar *' as an argument it just means that the said function garauntees that your string will not be modified by that function (whereas a `gchar *' argument is generally a return location for a single char). Here are some examples in GTK+ that do use static strings: http://developer.gnome.org/doc/API/2.0/gobject/gobject-Standard-Parameter-and-Value-Types.html#g-value-set-static-string http://developer.gnome.org/doc/API/2.0/glib/glib-Quarks.html#g-quark-from-static-string Usualy this behaviour is quite explicit :) Cheers, -Tristan ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
signal after form is built
It sounds like you are generating changed signals when you do not want to (ie when you are changing the text). I used the following to get rid of this problem: g_signal_handler_block_by_func(entryWidget, cb_function, data); gtk_entry_set_text(entryWidget, "newtext"); g_signal_handlers_unblock_by_func(entryWidget, cb_function, data); g_signal_stap_emissiona_by_name(entryWidget, "changed"); Sydney ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Gtk treeview use with large data sources
I have been searching for some time now to figure out how to approach using gtk treeview ( with a list model) with a sql database. I am using odbc on multiple platforms , hence gnomedb is not appropriate. Ideally the scrollwindow will behave as per using the standard list model. My questions: (1) should I write a custom list model that I can connect an odbc dsn & query to the treeview (2) should I disect gnome-db to find out the professionals approach it (3) should I give up and page the resultset into pages of 500 row that can be scrolled easily without Appreciate any sensible ideas Thanks Kim ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
