Re: Signal emitted when changing a combo selection?

[themac <themac club-internet fr>]

Hi,

Just check if your text entry is not empty

ex:

entry = GTK_ENTRY(GTK_COMBO(dwco__combo)->entry);
text = g_strdup_printf("%s", gtk_entry_get_text(entry));
if ( g_strcasecmp(text,"") )
{
... you 've got text
}
