I mailed the jextract list and Jorn Vernee explained that wayland use
opaque types, which are just defined as such:
struct wl_registry;
I guess you just pass it around and it's defined in the internal .c file.
Those are not supported by jextract.
I'll find a way to get around it.
But I've been playing with it all day, it seems very good. I was able to
generate bindings for:
GMain - for the main loop;
GSettings - for reading settings;
XDG Portal - for screen capture, screenshot, file dialogs
It looks like this:
1) To get a setting
try(var a = Arena.ofConfined()) {
var mouseSettings =
g_settings_new(a.allocateUtf8String("org.gnome.desktop.interface"));
int size = g_settings_get_int(mouseSettings,
a.allocateUtf8String("cursor-size"));
g_object_unref(mouseSettings);
return new Size(size, size);
}
2) Callbacks
@Override
protected void _invokeLater(Runnable runnable) {
MemorySegment call = GSourceFunc.allocate(p -> {
runnable.run();
return 0;
}, Arena.ofAuto());
g_idle_add(call, MemorySegment.NULL);
}
It looks correct to me, but untested.
