WxWidgets is a cross-platform GUI library.
escargo 2005-07-11: It would be interesting to know how well SWIG would gobble up the Wx Widgets code to produce an alternative binding that Tcl could use.
Maybe it is easier to make a binding to the wx-c.dll of the wx.NET-project on [L1 ]. This static library of the WxWidgets also exists for Linux and MacOS.
escargo 2005-07-11: It would be interesting to know the performance and complexity tradeoffs of the different methods for binding Tcl and the Wx Widgets. (I know that SWIG needs certain wrappers, but I don't know what the wx-c.dll binding would require.)
