Just to tidy up: I've rewritten the drawing of all the glyphs that looked wrong and the new gtk3 version is now installed. As far as I can see, it works perfectly. In fact the stave interface is...

It compiles! Hallelujah! It's still rather buggy: the edit function doesn't work yet, but I'm sure I can fix that. The glyphs (other than actual notes) mostly look awful but they can be improved...

You'll laugh! We already have the GList of glyphs! I'd completely forgotten about it, which shows you how long ago it is that I wrote this bloody thing. Of course when you use a program habitually,...

You misunderstand. I need to do this in stages, because I shall get completely mixed up otherwise. So stage 1 will be a simple conversion from gtk2/gdk2 to gtk3/cairo without changing the logic of...

Ha ha! That's what I'm doing already. You can't write a program as complex as this without using a few structs. It's just impossible.

I use two in this program actually and I don't know what I'd...

Yes, that could be one solution. There are a couple of gdk-cairo interface functions to translate pixbufs into cairo surfaces and vice versa.

I think there's a slight misunderstanding here. pmwScribe is not a complete music-writing program. Such a thing would be far beyond my capacity. As its name suggests, pmwScribe is just a convenient...

Ok. I've rejigged everything so that all primary drawing is now on the drawing area itself and not the pixbuf. I found some code on Stackoverflow for getting a cairo context for the widget (you get a...

Thanks. Presumably I'll need a separate context for the transfer from the one I've been using for drawing on the pixbuf. Can I get the surface (now the source) from the old context (which I assume...
