Hi, Cairo uses floating point values from 0.0 to 1.0 for colors, but apart from that your code should work with Clutter 1.16. For earlier versions you have to put the canvas into an extra actor instead of the stage. So long :wq buz On Thu, Oct 03, 2013 at 10:34:03PM +0200, Alessandro Re wrote:
Hello,
I was trying to draw with Cairo on a Content, but nothing shows up. I saw
some examples (included the one in the reference), but I can not see (what
I think are) notable differences.
Here's my code, can you please tell me what I am missing?
Thanks!
#!/usr/bin/env python3
import sys
from gi.repository import Clutter as clu
import cairo
def quit(*args):
clu.main_quit()
def draw_something(canvas, ctx, w, h):
ctx.set_source_rgb(0xff, 0x00, 0xff)
ctx.set_line_width(3)
ctx.move_to(0, 0)
ctx.line_to(w, h)
ctx.stroke()
return True
#def invalidate(canvas):
# canvas.invalidate()
# return True
if __name__ == '__main__':
clu.init(sys.argv)
black = clu.Color.new(0x00, 0x00, 0x00, 0xff)
stage = clu.Stage()
stage.set_color(black)
stage.set_size(200, 200)
stage.connect('destroy', quit)
stage.show()
canvas = clu.Canvas()
canvas.set_size(200, 200)
canvas.connect('draw', draw_something)
stage.set_content(canvas)
# clu.threads_add_timeout(0, 1000, invalidate, canvas)
canvas.invalidate()
clu.main()
