Tk Source Code

I expected the canvas moveto subcommand to move a text item to the specified location. However it ends up at some offset. The following code returns something like 24.0 17.0 instead of 10.0 10.0, as I would have expected.

canvas .c
set id [.c create text 0 0 -text hello]
.c moveto $id 10 10
puts [.c coords $id]

It seems that moveto actually uses the bbox coordinates of the text item rather than the coordinates as returned by the coords subcommand, judging by the fact that [.c bbox $id] returns "10 10 39 24" after the moveto.

If that is the intended behavior of the command, it could at least do with a clearer description in the manual page.

Merged into core-8-6-branch and trunk.

Indeed the "canvas moveto" command computes the translation vector from the upper-left corner of the item bounding box to the given moveto coordinates.

I made that clearer in the documentation in [98f7055781].
