Starting a Ruby GUI w/out showing the Klayout GUI

I am writing an application where I would like to use Klayout-supplied behavior but I don't need the normal Klayout user interface. I have written my GUI in
QT Designer as a .ui file that I load this way:

  module MyMacro
    include RBA

    HERE = File.dirname(__FILE__)
    UI   = File.join(HERE, '..', 'data', 'framebuilder5.ui')

    ui_file = QFile::new(UI)
    ui_file.open(QIODevice::ReadOnly.to_i)
    dialog = QFormBuilder::new.load(ui_file, Application::instance.main_window)
    ui_file.close
    dialog.show
  end

I don't know how to keep the Klayout GUI from appearing without taking away my
application's GUI capability. Can anyone suggest a solution?
My version of Klayout is 0.23.9 compiled with Qt 4.8.5 and Ruby 1.9.3 on RedHat Linux 5.6 (sorry I cannot update my OS).

Thanks,
Dave

    Hi Dave,

    The "-z" command line option is your friend. You can use it with "-r" to run a script without starting the application:

    Here is a sample:

    include RBA

dialog = QDialog.new(Application.instance.main_window)

dialog.setWindowTitle("Dialog Title")

dialog.resize(350, 300)

grid = QGridLayout.new(dialog)

windowlabel1 = QLabel.new(dialog)
windowlabel1.setText("Label")
edit = QTextEdit.new(dialog)
edit.enabled = false

ok = QPushButton.new("OK", dialog)
ok.clicked do 
  dialog.hide
end

grid.addWidget(windowlabel1, 0, 0, 1, 3)
grid.addWidget(edit, 1, 0, 3, 2)
grid.addWidget(ok, 4, 3)
grid.setRowStretch(3, 1)
grid.setColumnStretch(1, 1)

dialog.exec

    Save this to "dialog.rb" and run it this way:

    klayout -z -r dialog.rb
