Just a FYI.
I have no experience with 64bit assembler.
I did a little Linux 32bit jwasm testing with gtk eons ago :)
I want to get at least a basic understanding of the 64bit implementation.
My interest is sparked because I am working on a new cross platform Basic -> c/c++ translator with Glib/Gtk as the base.
I have run into many inconsistencies with the Gtk2/3 platforms on both Linux and Windows.
I have spent many hours with the assorted documentation scattered around the internet, but my old brain ......
You might want to revise your demos to not use depreciated gtk functions.
It took zetcode (
http://zetcode.com/gui/gtk2/) until this past July to update their offerings.
Looking forward to more info.
Am I correct there is not a working INVOKE for 64bit (Windows or Linux)?
