Embedding chaco in GTK

Question

Embedding Chaco into Qt and Wx seems to be no problem. Does anyone have an example or an idea how to embed Chaco into GTK?

Answer 1

I use python with matplotlib. To have a graphic inserted in the GUI, I need a "backend" : http://matplotlib.sourceforge.net/faq/installing_faq.html#backends

Code snippet :

from matplotlib.backends.backend_gtkagg import FigureCanvasGTKAgg as Canvas

Then, instance it (the add_subplot prepares a place for one plot) :

figsn  = matplotlib.pyplot.figure()
ax     = figsn.add_subplot(1,1,1)
canvas = Canvas(figsn)
...
snBox.pack_start(canvas, True, True)
canvas.draw()

So, what I want to say is that you need a "backend" from your package where you may be able to draw into, and that GTK can recognize. It suppose your chaco lib has to be compiled with GTK support. I can not install chaco here today, so please dig that way and let me know what you find !
