g_signal_handlers_block_by_func with gtk4-rs

[d47081]

I want implement following clang code with gtk4-rs. Is it possible using safe methods or this feature not implemented yet?

g_signal_handlers_block_by_func (entry, G_CALLBACK (editable_changed_cb), entry);
gtk_editable_set_text (GTK_EDITABLE (entry), new_url);
g_signal_handlers_unblock_by_func (entry, G_CALLBACK (editable_changed_cb), entry);

Well, found the answer in using RefCell with None combination, e.g.

signal_handler_id: Rc<RefCell<Option<SignalHandlerId>>>

then,

use gtk::prelude::ObjectExt;
if let Some(signal_handler_id) =
    signal_handler_id.borrow().as_ref()
{
    request.block_signal(signal_handler_id);
}
request.set_text(
    // change something
);
if let Some(signal_handler_id) =
    signal_handler_id.borrow().as_ref()
{
    request.unblock_signal(signal_handler_id);
}

• of course signal_handler_id should be captured somewhere outside, depending of app implementation.
