[Extension] written by [Donal Fellows] which allows arbitrarily shaped windows on [X%|%X11%|%] and [Windows] to be created. [MacOS] and [MacOS X] are not yet supported ''(but you can paint the appropriate areas with a transparent colour in [Tk] 8.5, and it should work anyway)''. http://www.man.ac.uk/~zzcgudf/tcl/#scripts/shape This is getting very interesting as it "homes in" on full cross-platform functioning. I found no instructions for building the Windows version. I suppose it blindingly obvious, but could you drop a few hints for us extension building neophytes? Or even post a dll? - [Roy Terry], 6Dec2003 [TkTrans] is a Windows-specific alternative. ---- 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] ''[DKF]: 27-Mar-2003 -'' It's on the [Tk 9.0 Wishlist]. ---- The extension appears to have moved to: http://www.cs.man.ac.uk/~fellowsd/tcl/shapeidx.html ---- 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. ====== wm overrideredirect [toplevel .some] 1 wm geometry .some 800x600+40+20 wm attribute .some -transparentcolor #C1C2C3 canvas .some.c -wid 800 -hei 600 -bg #C1C2C3 \ -bd 0 -relief flat -highlightthickness 0 pack .some.c -padx 0 -pady 0 -ipadx 0 -ipady 0 .some.c create oval 20 20 780 580 -width 1 -fill #ff0000 frame .some.c.w pack [label .some.c.w.t -text "Bonjour!
