There is a very ugly bug in qtruby. The following connections are no
longer working if the program needs more memory.
QObject.connect(SIGNAL(:signal)) do
puts 123
end
QObject.connect(SIGNAL(:signal),myobj,:mymethod) do
puts 123
end
The reason is that the garbage collector seems to delete the
Qt::BlockInvocation / Qt::SignalBlockInvocation / Qt::MethodInvocation
objects which are generated by the methods Internal.signal_connect,
Internal.method_connect and Internal.connect (qtruby4.rb:2862).
A fix for this would be a static array where a reference to each object
is stored.
Any suggestions?
Alex
