I would like to know how to manage (with QtRuby) the optional parameter from the constructor of a lot of classes (in Qt C++). I join a quick example. Thank you! Here is the code: require "Qt4" class Tree < Qt::TreeWidget def initialize parent # = 0 ??? (or something like that) # because I want this parameter to be # optional like in the parent class super parent end end class Window < Qt::MainWindow def initialize super # I have to use self whereas I want NO parameter setCentralWidget Tree.new self end end if __FILE__ == $0 a = Qt::Application.new ARGV g = Window.new g.show a.exec end -- Posted via http://www.ruby-forum.com/.
