self.area.window.draw_rectangle(gc, True, x, y, w, h)
self.area.window.draw_rectangle(gc, True, x, y, w, h)
The arguments for ''alloc_color'' are between 1-
The arguments for ''alloc_color'' are between 0-65535 and the ''set_source_rgb'' method from cairo are between 0-1, so we have to convert these values as well:
cr.set_source_rgb(0.762, 0.762, 0.762)
cr.set_source_rgb(0.762, 0.762, 0.762)
cr.fill()
cr.fill()
Note that the second attributo of ''draw_rectangle'' tells us about if the rectangle is filled or not. In this case is True, so we use ''cr.fill()'' in the new way but if we want just the outside lines of the rectangle we should use ''cr.stroke()''
