'''Python wrapper for the tkdnd tk extension.
|
||||
|
||||
The tkdnd extension provides an interface to native, platform specific
|
||||
drag and drop mechanisms. Under Unix the drag & drop protocol in use is
|
||||
the XDND protocol version 5 (also used by the Qt toolkit, and the KDE and
|
||||
GNOME desktops). Under Windows, the OLE2 drag & drop interfaces are used.
|
||||
Under Macintosh, the Cocoa drag and drop interfaces are used.
|
||||
|
||||
Once the TkinterDnD2 package is installed, it is safe to do:
|
||||
|
||||
from TkinterDnD2 import *
|
||||
|
||||
This will add the classes TkinterDnD.Tk and TkinterDnD.TixTk to the global
|
||||
namespace, plus the following constants:
|
||||
PRIVATE, NONE, ASK, COPY, MOVE, LINK, REFUSE_DROP,
|
||||
DND_TEXT, DND_FILES, DND_ALL, CF_UNICODETEXT, CF_TEXT, CF_HDROP,
|
||||
FileGroupDescriptor, FileGroupDescriptorW
|
||||
|
||||
Drag and drop for the application can then be enabled by using one of the
|
||||
classes TkinterDnD.Tk() or (in case the tix extension shall be used)
|
||||
TkinterDnD.TixTk() as application main window instead of a regular
|
||||
tkinter.Tk() window. This will add the drag-and-drop specific methods to the
|
||||
Tk window and all its descendants.
