GtkApplication? crash

Hi there. First of all, im new to Golang. I tried to make simple application with fake go "classes" abusing type structs and it always crashing after gtk_application_window_new. Regular hello world examples work just fine. However, GDB backtrace show something about gtk_style_provider_get_settings.
package main
import (
"github.com/diamondburned/gotk4/pkg/gio/v2"
"github.com/diamondburned/gotk4/pkg/gtk/v4"
"os"
)
type MainWindow struct {
window *gtk.ApplicationWindow
}
type App struct {
application *gtk.Application
mainWindow *MainWindow
}
func main() {
app := NewApp()
app.ConnectSignals()
app.Run()
}
//gtk.Application
func (a *App) init() *App {
a.application = gtk.NewApplication("com.example.test", gio.ApplicationFlagsNone)
a.mainWindow = NewMainWindow(a.application)
return a
}
func NewApp() *App {
return new(App).init()
}
func (a *App) ConnectSignals() {
a.application.ConnectStartup(func() { a.mainWindow.Construct(a.application) })
a.application.ConnectActivate(func() { a.mainWindow.Show() })
}
func (a *App) Run() {
if code := a.application.Run(os.Args); code > 0 {
os.Exit(code)
}
}
//gtk.ApplicationWindow
func (m *MainWindow) init(app *gtk.Application) *MainWindow {
m.window = gtk.NewApplicationWindow(app)
m.window.SetTitle("Test")
m.window.SetDefaultSize(300, 420)
return m
}
func NewMainWindow(app *gtk.Application) *MainWindow {
return new(MainWindow).init(app)
}
func (m *MainWindow) Construct(app *gtk.Application) {
var mainBox = gtk.NewBox(gtk.OrientationVertical, 8)
mainBox.SetMarginStart(8)
mainBox.SetMarginEnd(8)
mainBox.SetMarginBottom(8)
mainBox.SetMarginTop(8)
mainBox.SetVisible(true)
var topBox = gtk.NewBox(gtk.OrientationVertical, 8)
topBox.SetVisible(true)
var comboBox = gtk.NewComboBoxText()
comboBox.SetVisible(true)
mainBox.Append(topBox)
m.window.SetChild(mainBox)
}
func (m *MainWindow) Show() {
m.window.Show()
}

This code is really hard to read for me. Perhaps try looking at the hackernews example for how class-based applications are usually done. You're not really supposed to have an init() at all, and the Construct is kind of redundant.
Also, call NewApplicationWindow only within activate. All the examples should suggest that.
diamondburned commented
Examples are at https://github.com/diamondburned/gotk4-examples. Consider moving this issue there. I'm closing this one for now, since this issue doesn't really have to do with the bindings. Feel free to reopen it if you believe it's a bindings issue rather than something to do with your code.

Well i see now what's going on. GTKMM version has Gtk::ApplicationWindow no-param constructor version. And Gtk::Application pointer can be set via https://docs.gtk.org/gtk4/method.Window.set_application.html after.
