Category: Tkinter Group: Python 2.2.2 Status: Open Resolution: None Priority: 5 Submitted By: Roy Keir (newbieroy) Assigned to: Nobody/Anonymous (nobody) >Summary: Canvas origin is off-canvas in create_<item>(). Worka Initial Comment: The origin for x,y pairs sent to the Canvas items is off-screen by the sum of borderwidth bd and highlightthickness hT. The accompanying program shows this and includes three functions which can be used in workarounds. I just hope the upload facility works this time. A canvas with exaggerated values for bd and hT is shown to illustrate the problem. On it, a full-screen open rectangle ((0-to width-1) by 0-to-(height-1)) is shown in red, and it is partly off-screen. A blue rectangle of the same coordinates is sent through UsrToCnv(), which uses .cget() to fetch up-to-date values for bd and hT (which can of course be updated on the fly) and translates the user's canvas item back where it belongs. Clicking on the canvas illustrates the use of CnvToUsr, sending a tuple (event.x, event.y) through the reverse of the above translation so that it matches the user's expectations. If these functions or their equivalents are not already available, you have my permission to offer these as workarounds while someone investigates the problem. I recommend that similar trials be performed on Tcl/Tk or PERL/Tk to see if the problem lies in Tkinter or even deeper in the mass of code. I'm a Python beginner so can't help with a project to fix it, but I'd like to be kept informed of any progress or decisions, if that's not too much trouble.

If yes, in which version? Can you provide a test case? If the problem is solved, from which version? Note that if you fail to answer in one month, I'll close this bug as "Won't fix". Thank you! .
