Re: [Texmacs-dev] alpha-transparency

[Sam Liddicott]

Speaking mostly blindy, I think QT is what killed kylix (Delphi for Linux).  
wxWidgets (mostly seen by me with wxPython). Is what kylix should have used 
because it wraps native widgets on most platforms and presents a full platform 
API for gui apps.

However I don't think that is very relevant to texmacs but more of interest to 
those interested in this thread.
