RE: [gtk-list] Re: NEWBIE: Getting a Handle to an entry.

["Timothy M. Shead" <tshead sheaddataproc com>]

Maybe I'm misunderstanding the question, but it sounds like the "handle"
you're looking for is the widget pointer that's returned when you create the
widget ... why not store it, and use it in the callback for your "Clear"
button:

// Declaring the entries as globals
GtkEntry* entry1;
GtkEntry* entry2;
GtkEntry* entry3;

// Creating the entries
void CreateMyDialog()
{
	entry1 = gtk_entry_new();
	entry2 = gtk_entry_new();
	entry3 = gtk_entry_new();

	// Other initialization here
}

// The "Clear" button callback
void OnClearClicked()
{
	gtk_entry_set_text(entry1, "");
	gtk_entry_set_text(entry2, "");
	gtk_entry_set_text(entry3, "");
}

Cheerio,
