Gtk4 Drawing Area Example

This is a translated Vala version from the example at main Gtk4 Documentation

the only problem I couldn't find solusion for is that closing the window don't exit the process. And I can't connect to destroy signal. I don't know if it's a bug with Gtk4 or my fault.

Thanks to Chris Williams @chrisawi on irc.gnome.org #vala for the hint solving this issue.

Note

You have to compile and install Gtk4 on your machin. On ArchLinx you can build the Gtk4 AUR package.

Compile

run meson build, cd build, ninja.
