I want to create a suggestions drop down for a SearchEntry object in Gtk4 using Python.
In Gtk3 I can do the following to achieve my desired result:
import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk as gtk, Gdk
urls = [
"http://www.google.com",
"http://www.google.com/android",
"http://www.greatstuff.com",
"http://www.facebook.com",
]
liststore = gtk.ListStore(str)
for s in urls:
liststore.append([s])
completion = gtk.EntryCompletion()
completion.set_model(liststore)
completion.set_text_column(0)
completion.set_minimum_key_length(0)
def match_anywhere(completion, entrystr, iter, data):
modelstr = completion.get_model()[iter][0]
return entrystr in modelstr
completion.set_match_func(match_anywhere, None)
entry = gtk.SearchEntry()
entry.set_completion(completion)
# Show completion suggestions when the entry is focused
def on_focus_in(widget, event):
widget.emit("changed")
entry.connect("focus-in-event", on_focus_in)
header = gtk.HeaderBar()
header.set_show_close_button(True)
header.set_title("Search Entry")
header.set_custom_title(entry)
# boilerplate
window = gtk.Window()
window.set_titlebar(header)
window.connect("destroy", lambda w: gtk.main_quit())
window.show_all()
gtk.main()
However, this does not work in Gtk4, with the following error:
AttributeError: 'SearchEntry' object has no attribute 'set_completion'
Is there another way I could achieve the same result in Gtk4?
