[Kde-bindings] Why does this program stop ?

[Han Holl]

Hi,

I'm trying to construct a little program that shows the state of another 
computer (a mythtv recorder) in the systemtray.

After I click 'yes' the program stops, instead of hiding the dialog.

I have no idea why.

Cheers,

Han Holl

Here is the program, mercifully short:
#!/usr/bin/ruby -w
$KCODE = 'u'
$LOAD_PATH << File.dirname($0)
require 'Korundum'
class KdeTray < KDE::UniqueApplication
  k_dcop 'void set_state(int)'
  @@actions = %w{aan uit}
  @@buttons = %w{ button_cancel button_ok }
  slots 'yes()'
  
  def yes
    STDERR.puts "/usr/local/bin/tvr #{@@actions[@state]}"
    system("/usr/local/bin/tvr #{@@actions[@state]}")
    @w.hide
  end
    
  def caption
    "TVR #{@@actions[@state]}zetten"
  end
  
  def initialize
    super()
    @file = '/var/tmp/tvr-ready'
    @state = test(?f, @file) ? 1 : 0
    STDERR.puts caption
#    @main = Qt::HBox.new
    @caption = caption
    @w = KDE::DialogBase.new(@caption, KDE::DialogBase::Yes + 
KDE::DialogBase::No )
    @w.resize( Qt::Size.new(220, 50) )
    Qt::Object.connect(@w, SIGNAL('yesClicked()'), self, SLOT('yes()'))
    @tray = KDE::SystemTray.new(@w, 'tvr')
    setMainWidget(@w)    
    Qt::Object.connect(@tray, SIGNAL('quitSelected()'), self, SLOT('quit()'))
    @tray.setPixmap(iconLoader.loadIcon(@@buttons[@state], 
KDE::Icon::Toolbar))
    @tray.show
  end
  
  def set_state(state)
    @state = state
    @tray.setPixmap(iconLoader.loadIcon(@@buttons[@state], 
KDE::Icon::Toolbar))
  end
  
end
KDE::CmdLineArgs.init(ARGV, KDE::AboutData.new("tray", "", '', '', 0))
app = KdeTray.new
app.exec
