How Can I implement a Gtk.Widget snapshot func

[heloonihao]

i see gtk blog https://blog.gtk.org/2020/04/24/custom-widgets-in-gtk-4-drawing/ says ："To implement a widget that does some custom drawing, you need to implement the snapshot() function that creates the render nodes for your drawing" , it have same way in gir.core?

Do you have some minimal sample using some APIs?

You can check available APIs on the GirCore homepage too.

class CustomWidget ：Gtk.Widget
i think it shoud work like this,but ide tell me cant find func to override

[cameronwhite]

I think this involves overriding the snapshot() virtual function for a Gtk.Widget subclass, so it would be related to #182 ?

If overriding a virtual method is necessary then it is not yet supported like @cameronwhite pointed out.
