Hello folks,

Recently I've discovered that calling

  widget.visible()

causes a memory leak on Ruby1.9.
(Using .isVisible works correctly though).

On Ruby 1.8 both methods works alright.


Here's a quick test case:

require 'Qt4'
a = Qt::Application.new(ARGV)
hello = Qt::PushButton.new("Hello World!")
hello.resize(100, 30)
hello.show

while 1
  hello.visible
end

a.exec


Run it under ruby1.9 and watch resident memory usage in top
growing.

Best regards,
