Shape is an [Extension] written by [Donal Fellows] which allows arbitrarily shaped windows on [X%|%X11%|%] and [Windows] to be created. The latest release, Shape 0.4, was released in 2000. It supports X11 and Microsoft Windows only.

To this day, there is no known way to create shaped windows across all of X11, Windows and OS X.
''[DKF]: 27-Mar-2003 -'' It's on the [Tk 9.0 Wishlist].
***Windows***
[TkTrans] is a Windows-specific alternative.

In a discussion on https://groups.google.com/d/msg/comp.lang.tcl/X46x431qG3o/Qp47dRgyiOYJ%|%comp.lang.tcl%|% it is shown that you can get a shaped window even with plain Tcl on windows. However I would only use it for a splash screen.

[RLE] (2012-10-08): Note that the "-transparentcolor" option to [wm] attribute is documented as a Windows only feature (wm man page):
===
On Windows, the following attributes may be set.
...
-transparentcolor
Specifies the transparent color index of the toplevel. ...
===
***OS X***
tcltk-d: 2012-10-09
On MacOS10.6 wish V8.4
# (set w .anytoplevel)
$w conf -bg systemTransparent
wm attribute $w -transparent 1
may work!
weiwu: it doesn't on my OS X Sierra but it also doesn't through an error (where on Linux it would error that "systemTransparent" is an unknown colour.
*** Linux ***[[TkZinc]] used to support it. Now the project seems to have vanished.

Something like Shape needs to be combined with a '[drag and drop]' extension to allow proper dragging of arbitrarily shaped objects from, e.g. a [canvas] or a [text] widget (where you might want to drag a non-rectangular block of text).
Does anyone have plans to really add proper 'drag and drop' support to [Tk]? Any [TIP]s in the pipeline?
''[MGS]'' 2003/03/26 - I think the best bet may be [TkDND]
