GTK4 ListView non-homogeneous entries

[phragment]

Thank you everybody for your work on GTK4.
I’m currently messing around with ListView and trying different applications for it.
Putting composite widgets in it etc.
I find it really nice overall, but I have a question regarding the sizing of ListViewItems:
Is it possible to have them non-homogeneous?

Minimum Working Example

#!/usr/bin/env python3

import time

import gi
gi.require_version(“Gtk”, “4.0”)
from gi.repository import Gtk, GLib, Gio, GObject

class Application:

def __init__(self):
    self.app = Gtk.Application.new(None, 0)
    self.app.connect("activate", self.activate)

def run(self):
    self.app.run()

def activate(self, app):
    self.win = MainWindow(app)

class MainWindow:

def __init__(self, app):
    self.win = Gtk.ApplicationWindow.new(app)
    self.win.connect("close-request", self.on_window_close_request)

    self.win.set_title("Test ListView")
    self.win.set_size_request(300, 200)

    self.test_view = TestView()
    self.win.set_child(self.test_view.get_widget())

    self.win.show()

def on_window_close_request(self, window):
    self.win.close()

class Entry(GObject.Object):

def __init__(self):
    super().__init__()

def set_string(self, text):
    self.text = text

def get_string(self):
    return self.text

def create(self):
    return None

class TestView:

def __init__(self):
    self.sw = Gtk.ScrolledWindow()
    self.sw.props.hscrollbar_policy = Gtk.PolicyType.NEVER

    self.list_view = Gtk.ListView()
    self.sw.set_child(self.list_view)

    self.factory = Gtk.SignalListItemFactory()
    self.factory.connect("setup", self.on_factory_setup)
    self.factory.connect("bind", self.on_factory_bind)
    self.list_view.set_factory(self.factory)

    self.selection = Gtk.SingleSelection()
    self.model = Gio.ListStore()
    self.selection.set_model(self.model)
    self.list_view.set_model(self.selection)

def get_widget(self):
    return self.sw

def add(self, text):
    obj = Entry()
    obj.set_string(text)
    self.model.append(obj)

def on_factory_setup(self, factory, listitem):
    sw = Gtk.ScrolledWindow()
    label = Gtk.Label()
    sw.set_child(label)
    listitem.set_child(sw)
    listitem._label = label

def on_factory_bind(self, factory, listitem):
    label = listitem._label
    pos = listitem.get_position()
    item = listitem.get_item()
    text = item.get_string()

    label.set_label(text)

    sw = listitem.get_child()
    label.props.xalign = 0

    if pos % 2 == 0:
        label.props.wrap = Gtk.WrapMode.WORD_CHAR
        sw.props.hscrollbar_policy = Gtk.PolicyType.NEVER
    else:
        label.props.wrap = Gtk.WrapMode.NONE
        sw.props.hscrollbar_policy = Gtk.PolicyType.AUTOMATIC

def run_tests(app):

time.sleep(1)

text = "Jeder wackere Bayer vertilgt bequem zwo Pfund Kalbshaxen."

for i in range(1000):
    app.win.test_view.add(text)

#time.sleep(2)
#app.win.win.close()

if name == “main”:

app = Application()

GLib.idle_add(run_tests, app)

try:
    app.run()
except KeyboardInterrupt:
    pass

To maybe clarify things:
In the given example the entries are all the same size wether they are truncated or wrapped.
As such this probably does not make much sense. But it is only an example to show case my question.

Is it possible to make each entry only take up its “minimal size”?
