If you're using those calls, your combo box uses a list store as tree
model so the function below will suffice.
void remove_all (GtkComboBox *combo_box)
{
GtkTreeModel* model;
model = gtk_combo_box_get_model (combo_box);
gtk_list_store_clear (GTK_LIST_STORE(model));
}
Hope this helps.

Fullscreen application running?

It does help, thanks. No need for me to persue this on a more difficult

Signal Handling problems with own data
Hi, I am a newbie in gnome/gtk+ programming, and I have created a GUI that will perform some sign-in functions with a server. The user interface consists of a button called Sign-In and two text entries for username and password. I have inserted a g_signal_connect function in my program giving it as arguments the button, the clicked signal, and the function on_sign_in which I have written to perform the communication with the server. The problem I have is with the fourth argument of the g_signal_connect function. In the API it says that the last argument should be a gpointer to data. In my case I want to pass two widgets(the two text entries)so that when my function is called, to access the two text entries, grab their contents and validate the username and password with the server. How can I pass both the text entry widgets to the function that is called after the emission of the button click signal? I have read all the examples in the gtk tutorial, I have 3 books on gnome and gtk but I haven't found a single example which shows how to pass more that 1 widget to the function. Do I have to use the Gobject, which function of the API should I use? And if more than one widgets can be passed to the function, how can I access them ? I would appreciate your help very much, Nicolas. -- View this message in context: http://www.nabble.com/Signal-Handling-problems-with-own-data-tf2127300.html#a5869944 Sent from the Gtk+ - Apps Dev forum at Nabble.com. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

You can make a struct with the pointers to two widgets inside,
struct {
GetWidget *name, *pass;
} myTwoWidgets;
or an array of two pointers
GtkWidget *myTwoWidgets[2]
and pass a pointer to the struct/array as data. In both cases you will
have to typecast the gpointer in the handler to the corresponding type.
If you're using Glade, you can also pass the reference to the parent
window, and do lookup_widget (parent, ) for each widget inside the
handler.

Here you've got a full example:

int main(int argc, char **argv)
{
GtkWidget *dialog, *dialog_vbox;
GtkWidget *entry_name,*entry_password;
GtkWidget *button;
static GdkPixbuf *pixbuf;
GtkTreeModel *model;
TwoWidgets *widgets;
gtk_init (argc, argv);
dialog = gtk_dialog_new();
dialog_vbox = GTK_DIALOG (dialog)-vbox;
gtk_widget_show (dialog_vbox);
entry_name = gtk_entry_new ();
gtk_widget_show (entry_name);
gtk_box_pack_start (GTK_BOX (dialog_vbox), entry_name, TRUE, TRUE, 0);

button = gtk_button_new_from_stock (GTK_STOCK_APPLY);
gtk_widget_show (button);
gtk_box_pack_start (GTK_BOX (dialog_vbox), button, FALSE, FALSE, 0);
widgets = g_malloc(sizeof(TwoWidgets));
widgets-entry_name = entry_name;
widgets-entry_password = entry_password;
g_signal_connect ( button,
clicked,
G_CALLBACK (button_clicked),
widgets );
g_signal_connect ( dialog,
response,
G_CALLBACK (dlg_response),
widgets );
gtk_widget_show (dialog);
gtk_main ();
return 0;
}
Do I have to use the Gobject, which function of the API should I use?
You can use g_object_set_data and g_object_get_data on the button that
will be passed to the clicked callback:
// save as test2.c compile with:
// gcc -g test2.c -o test2 `pkg-config --cflags --libs gtk+-2.0`
// run with ./test2
#include gtk/gtk.h
void dlg_response (GtkDialog *dialog,
gint arg1,
gpointer user_data)
{
gtk_widget_destroy (GTK_WIDGET(dialog));
gtk_main_quit();
}
void button_clicked (GtkButton *button,
gpointer user_data)
{
gpointer *name, *password;
name = g_object_get_data (G_OBJECT(button), entry_name);
password = g_object_get_data (G_OBJECT(button), entry_password);
if( name password ){
g_print(Name: %s\nPassword: %s\n\n,
gtk_entry_get_text (GTK_ENTRY(name)),
gtk_entry_get_text (GTK_ENTRY(password)));
}
}
int main(int argc, char **argv)
{
GtkWidget *dialog, *dialog_vbox;
GtkWidget *entry_name,*entry_password;
GtkWidget *button;
static GdkPixbuf *pixbuf;
GtkTreeModel *model;
gtk_init (argc, argv);
dialog = gtk_dialog_new();
dialog_vbox = GTK_DIALOG (dialog)-vbox;
gtk_widget_show (dialog_vbox);
entry_name = gtk_entry_new ();
gtk_widget_show (entry_name);
gtk_box_pack_start (GTK_BOX (dialog_vbox), entry_name, TRUE, TRUE, 0);
entry_password = gtk_entry_new ();
gtk_widget_show (entry_password);
gtk_box_pack_start (GTK_BOX (dialog_vbox), entry_password, TRUE, TRUE,
0);
button = gtk_button_new_from_stock (GTK_STOCK_APPLY);
gtk_widget_show (button);
gtk_box_pack_start (GTK_BOX (dialog_vbox), button, FALSE, FALSE, 0);
g_object_set_data (G_OBJECT(button),
entry_name, entry_name);
g_object_set_data (G_OBJECT(button),
entry_password, entry_password);
g_signal_connect ( button,
clicked,
G_CALLBACK (button_clicked),
NULL );
g_signal_connect ( dialog,
response,
G_CALLBACK (dlg_response),
NULL );
gtk_widget_show (dialog);
gtk_main ();
return 0;
}
And if more than one widgets can be passed to the function, how can I access
them ?
This depends on the method you used.
