Re: How to identify a particular checkbutton ?

[Flavio Alberto Lopes Soares <flavio maqplas com br>]

Hi all,

In file interface.c (generated by Glade) :

  gtk_signal_connect (GTK_OBJECT (checkbutton_ponto09_20), "toggled",
                      GTK_SIGNAL_FUNC (on_checkbutton_ponto_toggled),
                      &ponto_data);


and the callback function :

void
on_checkbutton_ponto_toggled           (GtkToggleButton *togglebutton,
                                        gpointer         user_data)
{

  const gchar *nm;

  nm = gtk_widget_get_name(GTK_WIDGET(togglebutton));

  printf("NAME = %s\n", nm);

}

But when I run the program and I click on some checkbutton it prints :

NAME = GtkCheckButton
NAME = GtkCheckButton
NAME = GtkCheckButton
NAME = GtkCheckButton
NAME = GtkCheckButton
NAME = GtkCheckButton
.
.
.


I thought that would print :

NAME = checkbutton_ponto09_20
NAME = checkbutton_ponto09_23  
NAME = checkbutton_ponto09_22  
NAME = checkbutton_ponto10_20  
NAME = checkbutton_ponto11_29
.
.
.

as you said that your program does.

What's wrong ???

If work I will manipulate this string to know what checkbutton was clicked.

PS: Excuse-me for horrible english.

  
Thanks for all help
