[I originally posted this to gtk-app-devel-list, but I'm not sure that's the best place.] Is the Canvas on-topic for this list? If so, I have a few basic questions about it, which I hope are simple :) Firstly, which Canvas implementation should I be using? I've tried libgnomecanvas2, but I see there's also a FooCanvas, and a GtkCanvas (GTK+ 1.2 only?). Is the AA canvas still experimental and not recommended? I've been looking at George Lebl's "Piskvorky" canvas tutorial. (ftp://ftp.5z.com/pub/unix/gnome-piskvorky-1.tar.gz) After tweaking the Makefile to use pkg-config, this built fine with GTK+ 2.4/GNOME 2.8. However, I did find a problem: if I resize the window, the canvas viewable area becomes centred in the canvas widget, but the coordinates of button presses are still relative to the top left corner of the canvas widget, rather than the canvas view itself. How should I compensate for this in the code? Or is this a canvas bug, since the events are outside the drawable area? What I really want to do with the canvas is create a grid display system, similar to Gnumeric, but probably much simpler. What I want to do is achieve the same scroll behaviour as Gnumeric: the row and column labels scroll with the canvas, and scrolling is in discrete steps. How should I do this. I thought of two possible methods: - packing four canvas widgets into viewports in a GtkTable and tying their adjustments to the same scrollbars. - overlaying the row/column headings on top of the canvas relative to the scroll position. How does Gnumeric do this? I had a look, but couldn't find the relevant source files.
