Hi all,
I hope I read (and understood) the former e-mails correct, so here it goes:
1. The gtk_entry should have the signal "changed" attached so that if this
entry is changed the event handler kicks in.
2. In the callbacks.c a function something like on_gtk_entry_changed()
should exist.
3. In this function a static variable (global scope) defined like "gboolean
gtk_entry_changed = FALSE;" should be set to TRUE.
4. In the function on_dialog_button_ok_clicked() this entry should be read
with gtk_editable_get_chars().
5. Do something with the chars you got from gtk_editable_get_chars(). Not
the silly stuff I wrote, but a full working user checking mechanisme, code
based on checking against a list of known valid users.
see the following snippet:
--8<--------------------------------------------------------------
static gchar *my_dialog_some_entry_text;
static gboolean my_dialog_some_entry_changed = FALSE;
void
on_my_dialog_some_entry_changed(GtkEditable *editable, gpointer user_data)
{
my_dialog_some_entry_changed = TRUE;
}
void
on_my_dialog_button_ok_clicked(GtkButton *button, gpointer user_data)
{
extern GtkWidget *my_dialog_some_entry;
if(my_dialog_some_entry_changed)
{
my_dialog_some_entry = lookup_widget(GTK_WIDGET(button),
"my_dialog_some_entry");
my_dialog_some_entry_text =
gtk_editable_get_chars(GTK_EDITABLE(my_and_dialog_some_entry), 0, -1);
}
if(my_dialog_some_entry_text == g_strdup("known user"))
{
gtk_entry_set_text(my_dialog_some_entry, g_strdup("you have entered:
__known user__"));
}
else
{
gtk_entry_set_text(my_dialog_some_entry, g_strdup("you have entered
something else"));
}
}
--8<--------------------------------------------------------------
Do NOT forget to "g_free(*char);" the strings no longer needed !!
also look at:
http://developer.gnome.org/doc/API/2.0/glib/glib-String-Utility-Functions.ht
ml#g-strdup
or
