Hi, here is a simple example. From the appearing Dialog I want to
disable or hide some of the settings on the second page (page setup).

The reason why I want to disable some elements is, that I'm writing a
label editor (see at https://github.com/detlefreichl/etti ). And for
such a program it is really not useful if you i.e. can print double sided.

Cheers, detlef


#!/usr/bin/env ruby

require 'gtk3'

class Printer
    def initialize
        printOperation = Gtk::PrintOperation.new
        printOperation.n_pages = 1
        
        printOperation.signal_connect('draw-page') do |widget,
printContext, pageNumber|
            cc = printContext.cairo_context
            # drawing code
        end

        ret = printOperation.run :print_dialog
    end
end

printer = Printer.new
