#30 Toplevel Widget Cannot Be Drop Target

[Tim Tomkinson]

Starting in version 2.7, a toplevel widget can no longer be a drop target (tested on Windows only). A workaround is to create a frame inside the window which can act as the drop target, but this breaks all existing code.

For example, this works in 2.6 but not 2.7:

package require tkdnd
::tkdnd::drop_target register . DND_Files
bind . <<DropPosition>> {list copy}

Here is the workaround:

package require tkdnd
pack [frame .frame] -expand true -fill both
::tkdnd::drop_target register .frame DND_Files
bind .frame <<DropPosition>> {list copy}

Dear Tim,

Thank you for reporting this. It has been fixed, and the fix is in github:

It will be included in TkDND 2.8, which will be released shortly.
