[Kde-bindings] QT TextEdit refresh

[Carl Bourne]

Hi, 
 
I wonder if you can help. I'm currently exploring rubyqt in conjunction with the latest QT4 libraries. However, I can't seem to get a TextEdit widget to refresh properly. My code runs correctly when I click the button that has a ruby function assigned to it, but the TextEdit field does not update until the ruby function completes.
 
Here's the code I'm using:-
 
 
--------------------------------------------------------------------------------------------------
main.rb
----------
require 'Qt'
require 'dialog.rb'
app = Qt::Application.new(ARGV)
dialog = Dialog.new
dialog.exec
 
------
dialog.rb
-------
 
class MyWidget < Qt::Widget
  slots 'go()'
  def initialize(parent = nil)
    super(parent)
    setFixedSize(500, 500)
    @textedit = Qt::TextEdit.new(self)
    @textedit.setGeometry(5, 50, 480, 300)
 
    quit = Qt::PushButton.new(('Generate'), self)
    quit.setGeometry(5, 5, 100, 30)
    quit.setFont(Qt::Font.new('Arial', 12, Qt::Font::Bold))
    connect(quit, SIGNAL(:clicked)) {@textedit.clear();  go() }
  end
   
  def go
      #   @textedit.clear()
      @textedit.setText("Generating files:-")
      count = 0
      50.times do
        count+=1
        sleep 0.1
        @textedit.append("Generating file: "+count.to_s)    
        puts "hello"
      end
      @textedit.append("Done") 
  end
end
app = Qt::Application.new(ARGV)
widget = MyWidget.new()
widget.show()
app.exec()
