Hi Everyone, I have a behavior associated with a default binding with Tkinter Listbox that I want to get rid of but I can't no matter if I return "break" on the binding or unbind it directly. If you have a Listbox where the bounding box is not completely revealed in the window that holds it and you use the mouse to drag the list box, the contents of the listbox will move in the X direction to reveal the area that's hidden. After searching the internet for hours I found the behavior I want to remove is a default binding as described here:
http://tcltk.free.fr/man/TkCmd/listbox.php3 "[3] If the mouse leaves the listbox window with button 1 down, the window scrolls away from the mouse, making information visible that used to be off-screen on the side of the mouse. The scrolling continues until the mouse re-enters the window, the button is released, or the end of the listbox is reached. " After further searching I found that the code for this in tcl is described here: http://www.openmash.org/lxr/source/library/listbox.tcl?c=tk8.3 50 bind Listbox <B1-Motion> { 51 set tkPriv(x) %x 52 set tkPriv(y) %y 53 tkListboxMotion %W [%W index @%x,%y] 54 } Now I've found no way to successfully unbind B1-Motion from the listbox, as I said above. Nor return "break" on receiving the event. I do want to eventually have my own B1-Motion binding applied to the listbox for a different reason (with add='+' if necessary). My next step was to see if I could just unbind B1-Motion then programmatically delete tkListboxMotion in my code but tkListboxMotion is not available in the Tkinter source (it's part of a compiled binary I can't reach?). Any help would be greatly appreciated. Thanks! Roger. -- http://mail.python.org/mailman/listinfo/python-list
