I am rather sure that this doesn't have anything to do with
Python/Tkinter, though I actually hadn't checked with wish before. Ok, so
I set up this little tcl script:
#############################################
frame .f -bg yellow -width 400 -height 300
pack .f -fill both -expand 1
bind .f <Button-1> {puts "Button-1 event"}
bind .f <Enter> {puts "Enter event"}
bind .f <Leave> {puts "Leave event"}
#############################################
As expected, it's the same as with Tkinter, when the mouse button is
pressed, Enter and Leave events are triggered. So far it has been
reported that this does _not_ happen with MacOs, Gnome, IceWm. It's been
observed so far on Xfce, Lxde and just now Openbox-session (no surprise
probably, since Lxde seems to use Openbox, too).
Other mouse buttons show the same behavior. The same thing happened on
various systems, like Stretch, Sid, Ubuntu 19.04, Ubuntu 18.04.
Since it only seems to happen with Xfce/Xfwm and Openbox/Lxde I think it
is more likely that it is the window manager's fault than that of Tk.
Regards
Michael
