Re: libseed-list GTK+3 example?

[august <august alien mur at>]

I just updated seed from jhbuild.

when I run connected draw signal, it prints the following for the two
parameters:

[object GtkDrawingArea]
[object seed_struct]


The function is: 

function draw_arc( drawing_area, cr ){
	print(drawing_area);
	print(cr);
	return false;
}


Do I need to updae WebKit or GIR files somehow?


thanks - august.
