How to avoid freezing a rubygnome GUI?

Desktop Ruby-Gnome 2
1

Hi guys,

Here is my problem.

I have a GUI widget, in ruby-gnome, and I have buttons.

Each button plays a video file.

I use system() for this, and mplayer.

When I click the button, all works well, mplayer plays the
video.

The problem is that, while mplayer plays this file, the
rubygnome GUI “freezes”, until that mplayer window is
closed again.

Is there a way to somehow allow the background GUI frame
to not freeze? On the commandline I can play multiple
videos, from different KDE konsole tabs, so I wonder that
must be possible in a GUI too, perhaps via a thread or
something.

Thank you.

On an ancient version of ruby-gnome, I used this to do something
similar:

def threaded()
if(block_given?)
@_w_events = @window.events
@window.events = 0
@window.sensitive = false
@window.window.cursor=Gdk::Cursor.new(Gdk::Cursor::WATCH)

  Thread.new do
    begin
      yield
    rescue
      #error($!)
    end

    @window.window.cursor = nil
    @window.events = @_w_events
    @window.sensitive = true
  end
end

end

And then wrap whatever I needed to run like this.

threaded() do
play_video()
end

You might need to make a few modifications though, because it was on an
ancient version of ruby-gnome, and on Ruby 1.8.6.
