Hiding transition in Gtk

This is a continuation of a previous question on the Gtk.SearchEntry widget.

In that question I manage to reveal the entry widget upon clicking in the icon, now I want the widget to disappear after it loses focus.

The approach used now was with:

    search_entry.icon_release.connect (hide_search)

And defined hide_search as:

def hide_search()
    search_button_revealer.set_reveal = true
    search_entry_revealer.set_reveal = false
    show_all()

However, this does not solve the problem. The entire code can be found here.

You seem to be grabbing the wrong signal. The one you have is for when you click the button inside the entry while the one you need is focus_out_event, this is the vala code that makes what you want :)

search_entry.focus_out_event.connect (() => {
    // Make sure the entry is empty so you don't 
    // close it out on the user
    if (search_entry.get_text () == "") {
        hide_search ();
    }

    return false;
});
