Use

  thecanvas.winfo_width()

This works for any widget, not just canvas.


Here's a list of all the winfo_... methods, taken from Tkinter.py:

	def winfo_atom(self, name, displayof=0):
	def winfo_atomname(self, id, displayof=0):
	def winfo_cells(self):
	def winfo_children(self):
	def winfo_class(self):
	def winfo_colormapfull(self):
	def winfo_containing(self, rootX, rootY, displayof=0):
	def winfo_depth(self):
	def winfo_exists(self):
	def winfo_fpixels(self, number):
	def winfo_geometry(self):
	def winfo_height(self):
	def winfo_id(self):
	def winfo_interps(self, displayof=0):
	def winfo_ismapped(self):
	def winfo_manager(self):
	def winfo_name(self):
	def winfo_parent(self):
	def winfo_pathname(self, id, displayof=0):
	def winfo_pixels(self, number):
	def winfo_pointerx(self):
	def winfo_pointerxy(self):
	def winfo_pointery(self):
	def winfo_reqheight(self):
	def winfo_reqwidth(self):
	def winfo_rgb(self, color):
	def winfo_rootx(self):
	def winfo_rooty(self):
	def winfo_screen(self):
	def winfo_screencells(self):
	def winfo_screendepth(self):
	def winfo_screenheight(self):
	def winfo_screenmmheight(self):
	def winfo_screenmmwidth(self):
	def winfo_screenvisual(self):
	def winfo_screenwidth(self):
	def winfo_server(self):
	def winfo_toplevel(self):
	def winfo_viewable(self):
	def winfo_visual(self):
	def winfo_visualid(self):
	def winfo_visualsavailable(self, includeids=0):
	def winfo_vrootheight(self):
	def winfo_vrootwidth(self):
	def winfo_vrootx(self):
	def winfo_vrooty(self):
	def winfo_width(self):
	def winfo_x(self):
	def winfo_y(self):
