.Net 8 bindings for GTK 4
Gtk4DotNet uses a functional declarative approach to GTK4 similar to REACT or Kotlin Compose:
return Application
.New("org.gtk.example")
.OnActivate(app =>
app
.NewWindow()
.Title("Hello Gtk👍")
.SideEffect(win => win
.Child(
Grid
.New()
.Attach(
Button
.NewWithLabel("Button 1")
.OnClicked(() => WriteLine("Button1 clicked")), 0, 0, 1, 1)
.Attach(
Button
.NewWithLabel("Button 2")
.OnClicked(() => WriteLine("Button2 clicked")), 1, 0, 1, 1)
.Attach(
Button
.NewWithLabel("Quit")
.OnClicked(() => win.CloseWindow()), 0, 1, 2, 1)))
.Show())
.Run(0, IntPtr.Zero);
}
You don't have to use window.ui XML files for describing the UI, instead declare the UI declarative with C#.
Contained in this Repo are samples how to use Gtk4DotNet. All examples of the official GTK4 are transformed to C# with Gtk4DotNet.
if you want to use WebView (WebKitGTK) on Ubuntu 22.04:
- sudo apt install libwebkitgtk-6.0-dev
With LibAdwaita
- sudo apt install libadwaita-1-dev
Gtk4
- sudo apt install libgtk-4-dev
- sudo apt install libglib2.0-dev-bin
sudo install -D ./Test/org.gtk.example.gschema.xml /usr/share/glib-2.0/schemas/
sudo glib-compile-schemas /usr/share/glib-2.0/schemas/
Look at the sample programs (https://github.com/uriegel/Gtk4DotNet/tree/Main/Test)
To check if GObjects are being freed, just run
Widget.AddWeakRef(() => Console.WriteLine("... is being freed));
If this object is finalized, then the callback will be called.
